Responsibility for Epidemics

Article - Volume 97 - Issue 2

Epidemics are the result of the actions of multiple actors, which necessitates a comprehensive allocation of responsibility. However, the traditional framework for responsibility, as well as the emerging norm of the responsibility to protect, are inadequate for addressing epidemics. Both perpetuate the fallacy that states can, on their own, cope with the increased incidence of epidemics and fail to adequately allocate responsibility.

Given these limitations, this Article argues for a new vision of responsibility. It develops the theory underlying the norm of common but differentiated responsibility and makes the case for expansion of this framework to the challenges posed by highly-infectious diseases. This Article articulates the distinctive normative bases for differentiating responsibilities based on need, culpability, and capacity. The framework developed herein better distributes responsibility and is less state-centric than rival norms. It accounts for structural inequality in ways that other frameworks do not. Further, it does not reify the false hierarchy between civil and political rights and economic and social rights that exists in other frameworks. It recognizes and accounts for the significant role of nonstate actors and provides a basis for holding such actors responsible, as opposed to the nonattribution of responsibility that exists.

There is reason for cautious optimism about the prospects of success of this framework. First, it is consistent with theoretical and existing foundations of law where responsibility is tethered to an actor’s conduct and relationship to the harm through culpability. However, the framework does not treat the culpability model as a legal straitjacket and envisions a broad understanding of causation—direct, indirect, and historical. Additionally, the framework differentiates based on capacity, which is derived from human rights and global public health law. It also draws on extralegal incentives, building on moral and political conceptualizations of responsibility towards those in need. The common but differentiated responsibility framework is likely to gain approval and assist rapidly with the battle against epidemics. In fact, elements of it are already reflected in state practice. In sum, the theoretical framework developed in this Article serves not only to provide useful guidance to actors in the face of epidemics but also to shift extant conceptualizations of responsibility in significant ways.


I. Introduction

Worldwide highly-infectious diseases reflect global inequities: they make up five of the top ten leading causes of death in low-income countries, while constituting only one of the top ten causes of death in high-income countries.[1] Cholera is an infectious disease that impacts the poorest of the poor,[2] and like other highly-infectious diseases marked by poverty, such as Ebola, it has received inadequate attention. Cholera is now endemic in many countries.[3] Yet endemic outbreaks of Cholera are distinguished from epidemics, wherein a significant increase of cases occurs in an area.[4] While Cholera seems to have a relatively long and stable relationship with humankind,[5] major epidemics generally do not occur in the Global North[6] but continue to happen in the Global South. For example, in 1961 a Cholera pandemic began in Indonesia and spread to six continents,[7] touching South Asia (1963), Africa (1970), Latin America (1991), and the Caribbean (2010).[8] Peru’s outbreak took place 100 years after the disease had been eliminated from South America; its spread across the continent led to the death of 10,000 people.[9] Yemen is currently facing the largest documented Cholera epidemic in modern times, with over a million cases suspected and over 2,300 deaths reported.[10]

Highly-infectious diseases typically do not respect borders, posing transnational challenges that require cooperation and action through law. This was witnessed with HIV/‌AIDS, where one case in 1959[11] led to 36.9 million people worldwide living with the disease by the end of 2017.[12] Indeed, due to the increasing interconnectedness of the world and the influence of a warming climate on the spread of highly-infectious diseases, previously obscure viruses are unlikely to be contained to the periphery. As old infectious diseases increase in incidence and geographic distribution, or reemerge where they were previously under control, new epidemics continue to surface. Further, there is increasing resistance to current drugs. Accordingly, epidemics force us to consider: Who is responsible for combating highly-infectious diseases? How should that responsibility be allocated? What should such responsibility look like? These questions are especially important for vulnerable countries that are not able to cope with epidemic disease.

In January 2010, a massive earthquake hit Haiti, killing thousands, leaving hundreds of thousands homeless, and devastating already weak infrastructure in the country. The earthquake created ripe conditions for Cholera. Nepalese peacekeepers that were part of the United Nations Stabilization Mission in Haiti introduced the virus in October 2010 near the Arbonite River, a main source of drinking water in Haiti.[13] The source of the initial outbreak is no longer disputed; the viral strain in Haiti’s river was a “perfect match” to the Nepali strain.[14] Due to poor sanitation conditions, a twenty-eight-year-old Haitian man became exposed to Cholera while using the river near the peacekeepers’ camp;[15] he died shortly thereafter. Scientists labeled him “Patient Zero” because members of his family who assisted with his burial became ill themselves.[16] Within a year, approximately 4,000 people had died from Cholera.[17] The contamination resulted in an epidemic in Haiti that has caused the death of 9,603 people and the infection of over 812,000 people at the time of writing.[18] The epidemic in Haiti raises crucial questions about responsibility.

Comparable questions also arose during the largest Ebola epidemic in history, which occurred in 2014–2015 in West Africa. Epidemiologists identified Emile Ouamouno as “Patient Zero.” Emile was a two-year-old child in Guinea when he got infected with a mysterious fever that spread to his family members, a rural health facility, a health worker’s funeral, and—through related familial, social, and trading networks—to the Liberian, Guinean, and Sierra Leonean borders.[19] This pattern—where an infected person goes to an under-resourced health facility without clean needles, a supply of gloves, or other necessities for successful treatment and containment of the disease, rendering both the patient and healthcare providers vulnerable and susceptible to transmission—resulted in the Ebola virus inevitably being transmitted.[20] Gaps in core capacities were especially pronounced in Guinea, Liberia, and Sierra Leone[21] because, concomitant with structural factors, the subregion had a recent history of conflicts and narrow post-conflict reconstruction, which cumulatively hollowed out the health sector.[22] Due in part to the role of international laws and institutions, these states lacked the capacity to prevent the domestic and transnational spread of the disease.[23] The World Health Organization (WHO) estimates that this outbreak resulted in 28,616 cases of Ebola and 11,310 deaths in Liberia, Sierra Leone, and Guinea alone.[24]

This Article uses the Cholera and Ebola epidemics to demonstrate the limitations of the law of responsibility for addressing epidemics. Both epidemics are ideal for this study because they resulted in a lack of responsibility. While the Cholera epidemic implicates clear lines of causation, the Ebola epidemic involves more diffuse and indirect lines of causation. Both involve structural factors, multiple actors, as well as historical and more contemporary action. The case studies of the Ebola and Cholera epidemics demonstrate quite vividly why conventional and emerging responsibility frameworks fail to find purchase in the context of global public health.

This Article argues that a common conceptualization of responsibility is necessary to effectively deal with highly-infectious diseases given their potential to become worldwide pandemics. It maintains that the traditional framework for responsibility, as well as the emerging norm of the Responsibility to Protect (R2P)[25] are inadequate for addressing challenges posed by epidemics. This Article proposes a common but differentiated responsibility (CBDR)[26] framework to fight highly-infectious diseases. It recommends this as a new vision of shared responsibility for epidemics.


This Article recommends a common but differentiated framework of responsibility to:

(1) recognize special situations of need in one or more countries with epidemic diseases;

(2) assign greater responsibility to those who have contributed more to an epidemic; and

(3) assign greater responsibility to those who have more resources or capacity to deal with an epidemic.

It develops the framework of CBDR and extends and applies it to

highly-infectious diseases in a way that directly addresses the shortcomings of existing responsibility paradigms. First, both the traditional principles of responsibility and R2P perpetuate the fallacy that states can cope with structural problems on their own, including the increased incidence of epidemics. The framework developed herein better distributes responsibility and is less state-centric than rival norms. Additionally, it does not reify the false hierarchy between civil and political rights and economic and social rights that exists in other frameworks. It also recognizes and accounts for the significant role of nonstate actors and provides a basis for holding such actors responsible, as opposed to the lack of responsibility that otherwise exists.

While some scholarship exists on responsibility for highly-infectious diseases,[27] few have sought to relate this to why extant approaches to responsibility should be reconceptualized.[28] This author does so, drawing widely on criminal law, tort, and remedies principles to formulate the core argument that existing frameworks are insufficient to address global public health threats like highly-infectious diseases. This Article develops the theory underpinning CBDR as a framework based on insights gleaned from its application to the Cholera and Ebola epidemics. It develops a theoretical framework of responsibility for epidemics (an area where international consensus exists on its salience), cognizant that this framework could be expanded and applied to cover more diseases and adapted to apply to other fields outside of global public health in the future.

This Article is organized as follows: Part II covers the legal framework—examining global public health law, human rights law, and the law of responsibility. Additionally, it demonstrates that the emerging norm of R2P represents an incomplete vision of responsibility and is inadequate to combat epidemics. Part III proposes the expansion of common but differentiated responsibility and develops a framework for battling epidemics. Part IV discusses the theoretical and policy implications of this Article—resolving inter- and intra-axis conflicts within the framework and exploring the limits of diffusion, as well as the issues raised with operationalizing CBDR in hard and soft law. The CBDR framework is broad enough to resonate with diverse actors and assist quickly in fighting

highly-infectious diseases. For example, the Global Health Security Agenda (GHSA) is currently working to address threats posed by highly-infectious diseases through voluntary commitments made by members.[29] This initiative incorporates elements of the CBDR framework by differentiating based on capacity and need.[30] As such, elements of the framework are already reflected in state practice. This Article serves not only to provide useful guidance to actors in the face of epidemics but also to shift existing paradigms of responsibility in novel ways.


II. Legal Framework

States use international law and institutions to achieve common aims, solve shared problems, promote compliance with norms, reduce transaction costs, provide information, and coordinate orderly and peaceful dispute resolution. States also utilize international law to confront problems that overwhelm and transcend traditional boundaries. International law increasingly addresses every type of human activity, including those typically considered within the exclusive domestic jurisdiction of states—like public health and the treatment and prevention of epidemics. Prevention of epidemics is a shared concern of states. However, states have differential capacity to prevent and manage epidemics.

The legal framework for addressing pandemics is spread across multiple regimes. Global public health law is the most specific field regulating epidemics. The framework for determining responsibility for violations that arise during epidemics is governed by human rights law, while the regime for allocating responsibility for epidemics is located under principles of responsibility. Reconceptualizing responsibility is a project reflected in burgeoning shared responsibility norms like R2P. The below subparts indicate the limitations of each of these fields for combating epidemics and demonstrate why a new vision of shared responsibility is necessary.


A. Responsibility for Combating Epidemics in Global Public Health and Human Rights Law

1. Responsibility for Combating Epidemics in Global Public Health.—The primary regime for regulating disease is global public health law. The International Health Regulations of 2005 (Regulations)[31] is the core instrument. Its main purpose is to “prevent, protect against, control and provide a public health response to the international spread of disease . . . .”[32] The Regulations create a system of state surveillance and notification for certain infectious diseases, which would then trigger an international response.[33] The Regulations articulate the procedures and framework for emergency decision-making in the event of a public health emergency of international concern.[34]

Global public health law assigns principal responsibility for implementing health measures to combat highly-infectious diseases to national authorities and component parts.[35] The Regulations provide that states are to develop better functioning health systems to detect disease, surveil, report, verify, and respond, among others.[36] The state-centric nature of the Regulations fails to adequately recognize the structural conditions in the international system that give rise to states needing to develop core capacities. It is of limited utility because it does not assist with determining responsibility beyond the affected states. It also does not assist with how responsibility for capacity-building should be allocated. Overall, global public health law is an incomplete regime for conceptualizing and allocating global responsibility for combating epidemics.

 

2. Responsibility for Combating Epidemics in Human Rights Law.—Another important framework for addressing epidemics is human rights law. Under it, states have three kinds of duties—to respect (not to intrude on rights), to protect (to restrain third parties from violating rights), and to fulfill (requiring states to help realize positive rights).[37] The Ebola and Cholera epidemics implicate several fundamental human rights, including protections against the arbitrary deprivation of life[38] and the right of everyone to the enjoyment of the highest attainable standard of physical and mental health.[39] Under the International Covenant on Economic, Social and Cultural Rights, affected states are to take primary responsibility to prevent, treat, and control epidemic diseases.[40]

Additionally, a fundamental principle of economic, social, and cultural rights is that a state should “undertake[] to take steps . . . to the maximum of its available resources, with a view to achieving progressively” the right to health as well as other economic, social, and cultural rights.[41] “When the State has taken all reasonable steps to the maximum of its available resources, but for reasons beyond its control . . . is still unable to implement its obligations, then it bears no responsibility . . . .[42] It is more likely that human rights bodies will find states to be unwilling and in violation of their obligations as opposed to unable in the vast majority of cases.[43] This is because even where resources are strained, a state cannot justify noncompliance with any of its core obligations, which include the provision of essential levels of healthcare.[44] The Committee on Economic, Social and Cultural Rights, the enforcement body responsible for interpreting the Covenant on these rights, has found that a state claiming that it is unable to carry out its obligations for reasons beyond its control has the burden of proof.[45] Further, that state must also demonstrate that it has unsuccessfully sought to obtain international support.[46] Thus, human rights law does not absolve states that are incapable from responsibility; instead, it requires that they progressively develop capabilities to secure socioeconomic rights. Given the above, it should be the rare case that a state affected by an epidemic would be able to shield itself from responsibility.[47]

Nonetheless, states and other international actors tend to perceive civil and political rights violations as more severe and deserving of responsibility and action. Thus, no matter how prolonged or systematic socioeconomic violations are, these violations tend to “recede drably into the background” without external obligation or action.[48] In part, this is due to the erroneous position that determining accountability for breaches of civil and political rights is more straightforward than for economic and social rights.[49] Some countries have not recognized socioeconomic rights as legally binding primary obligations.[50] Accordingly, violations of socioeconomic rights are perceived as less amenable to attribution of responsibility and subsequent accountability efforts. This neglect of the importance of the economic and social sector in international law has rendered already vulnerable countries in the Global South ill-equipped to deal with public health crises posed by epidemics.

While the Committee has held that “all members of society—individuals, including health professionals, families, local communities, intergovernmental and nongovernmental organizations, civil society organizations, as well as the private business sector—have responsibilities regarding the realization of the right to health,[51] this is not reflected in people’s lived experiences. Only state parties to the Covenant on Economic, Social and Cultural Rights are accountable for compliance with it.[52] While states’ international obligations include ensuring that their actions as members of international institutions take due account of the right to health,[53] this does not always occur. Unfortunately, the law on the books is not always reflected in reality. For example, state actors tend to regard economic and social rights as territorial,[54] even though the Committee has found that member states are also to respect the enjoyment of the right to health in other countries.[55] The Committee has stipulated that states are also to prevent third parties from violating the right to health in other countries if states are able to influence third parties by way of legal or political means that do not conflict with other international obligations.[56] The Committee has also opined that state parties should provide an environment that facilitates the discharge of responsibilities on the right to health.[57] Yet, this similarly does not pertain. One of the salient issues that arises when the obligation to realize the right to health shifts to the international community is that “an undistributed duty . . . to which everybody is subject is likely to be discharged by nobody unless it can be allocated in some way.”[58]

Human rights law is an inadequate regime for conceptualizing and allocating responsibility for epidemics. First, the hyper-prioritization of the protection of civil and political rights over social and economic rights frustrates efforts aimed at combating highly-infectious diseases. Human rights law assigns responsibility for combating epidemics to the affected state primarily and to everyone else secondarily. This presents substantial challenges for providing full redress for violations witnessed with epidemics. The law of responsibility hypothetically fills the gaps where the above regimes leave off, but the next section demonstrates its limitations.


B. Allocating Responsibility for Epidemics

When dealing with indivisible harms like epidemics, there are inevitable challenges in attributing responsibility under traditional principles because it is difficult to determine what specific actor caused the exact action that subsequently produced a definite aspect of the damage witnessed.[59] Indivisible harms can be caused by governments—acting individually or collectively—international and regional organizations, civil society, corporations, community-based actors, and individuals, amongst others.

Yet, conventional understandings locate responsibility solely at the level of the state.[60] The traditional view of state responsibility under Article 2 of the International Law Commission’s Draft Articles on Responsibility of States for Internationally Wrongful Acts holds that states are responsible only for conduct attributable to them through action or omission.[61] The general rule is that conduct is attributable to the state when it is committed by an organ of the government or when a person or entity is acting as an agent of the state and exercising elements of governmental authority.[62] However, a state can also be responsible to the extent it fails to take necessary measures to prevent harm, imposing a standard of due diligence.[63]

States generally resist principles of responsibility that would hold them responsible for conduct other than their own—whether those other actors are private, international organizations, or other state actors.[64] The way the International Law Commission attempts to deal with situations where there are multiple state actors responsible for wrongdoing is unsatisfactory. It does not clarify how responsibility is to be allocated.[65] Moreover, states are no longer the only relevant actors in the international order. The law of responsibility obscures the activities of international organizations, as well as other nonstate actors and the harm that results from their actions.

Accordingly, “responsibility gaps[66] can occur in many ways. First, a responsibility gap may persist during pandemics because it is not obvious who should respond. This may lead to a bystander effect where no actor responds.[67] A responsibility gap may also occur because the individual actions of multiple actors may be distributed in a way that does not meet the legal requirements, which provide that responsibility is only assigned to actors whose individual contributions are significant enough to pass the minimum threshold.[68] Notably, in other areas of law, problems of overdetermination[69] are dealt with by a number of doctrines—joint and several liability in tort law and joint criminal enterprise in international criminal law, by way of example.[70] These principles have not been incorporated into the law of responsibility.[71] This likely reflects the practical consideration that the higher the risks of responsibility, the more cautious actors will be in accepting obligations.

Even if actors are willing to accept higher obligations, all international dispute settlement mechanisms are premised on state consent, and most do not have jurisdiction over other international institutions or corporations.[72] Thus, a responsibility gap will likely be maintained where a harm occurs during an epidemic because adjudication of a claim may not be able to proceed against the state if it withholds its consent to jurisdiction and, in any event, would not include other international actors involved.

The law of responsibility is the extant framework for determining secondary obligations. It is also an imperfect regime for conceptualizing and allocating responsibility for combating epidemics because to address many of the most pressing problems, states acting alone will be powerless to make any significant difference.[73] The state-centric nature of the law of responsibility leaves important nonstate actors outside the circle. The law of responsibility, like other areas of law, is not neutral, as even the non-attribution of responsibility is a method of distributing responsibility. It reflects choices and practices of states. The sections below examine the conventional law of responsibility and illustrate its limitations as applied to addressing highly-infectious diseases.

1. Cholera & Allocating Responsibility.—“Cholera is an acute diarrhoeal infection caused by ingestion of food or water contaminated with” the Cholera bacteria.[74] Most infected people display only mild symptoms and recover with minimal treatment.[75] However, in some infected individuals the disease can lead to severe dehydration and death if treatment is not promptly administered.[76] The WHO estimates that every year there are approximately 1.3 to 4 million cases of Cholera and an estimated 21,000 to 143,000 deaths worldwide.[77]

In October 2010, Cholera tragically reemerged in Haiti for the first time after a century. Following the outbreak, the U.N.’s Panel of Independent Experts found that its peacekeepers and its failure to establish proper sanitation systems in its camps were not the but-for causes of the epidemic. Instead, the organization blamed “water and sanitation and health care system deficiencies . . . coupled with conducive environmental and epidemiological conditions” for allowing Cholera to spread.[78] The U.N. blaming conditions in Haiti—which has prompted it to repeatedly intervene in the country for the spread of the epidemic—is illuminating. This is especially so when one considers that reconstruction efforts following the earthquake neglected the importance of reviving and building robust institutions aimed at the detection, prevention, and control of communicable diseases.

Scholars have criticized the U.N.’s response for being both a public relations and public health disaster.[79] A U.S.-based NGO working with lawyers in Haiti sent a petition to the U.N. Secretary General with 5,000 signatures presenting a number of legal arguments.[80] After over a year, the U.N. responded by dismissing those arguments as “not receivable” given the organization’s immunity under the General Convention on the Privileges and Immunities of the United Nations.[81] Three separate class action lawsuits were also brought in New York against the U.N.[82] Its response in the face of these claims is heartbreaking but unsurprising.[83] On September 26, 2018, Haitian human rights lawyers requested an emergency injunction before the Tribunal de Première Instance de Port-au-Prince against the State of Haiti, which would compel it to trigger the creation of a standing claims commission.[84] If created, the commission could potentially address claims arising from the Cholera epidemic in Haiti. A standing claims commission is envisioned as the primary means for the settlement of disputes based on the Status of Forces Agreement in effect between the United Nations and Haiti.[85]

To date, the U.N. has continued to skirt responsibility[86] and has not compensated those harmed for its role in enabling the spread of Cholera in Haiti. A potential remedy to this responsibility gap is the International Law Commission’s proposal to make states responsible in certain situations where they delegate authority to an international organization, which then violates rights.[87] The proposal would hold states responsible even where the injury was solely attributable to the international institution.[88] The International Law Commission has also proposed that an institution can be responsible in connection with the wrongful acts of states where, for example, the organization adopts a decision that requires states to commit acts that contravene international obligations.[89]

Notably, the Draft Articles on the Responsibility of International Organizations recognizes that in situations of internationally wrongful acts where there is concerted action between international organizations and states, both the states and the organizations have shared responsibility.[90] The Draft Articles also provide for shared responsibility between international organizations.[91] While the Draft Articles potentially improve upon the status quo, they still fail to account for cumulative action. They also do not clarify how responsibilities are to be allocated amongst multiple actors.[92] For example, international institutions increasingly also have public–private partnerships and rely on private actors, especially in the field of global public health.[93] It is unclear how responsibility is to be apportioned in instances of violations of the right to health with public–private partnerships. Furthermore, the Draft Articles do not yet have the status of law. Even if they are interpreted as binding, most international organizations and private actors, like corporations, may not necessarily be bound by international law obligations or even soft law in many areas, and if they are, their obligations may not be the same as those of states.

Relatedly, the regime governing jurisdiction over international institutions is meek—they are immune from suit domestically, and typically, no court has jurisdiction. International organizations like the U.N. have been found to have legal personality,[94] which enables them to make claims and to have claims made against them. Under the current regime, international organizations are legally responsible only for the wrongs they choose to be responsible for.[95] Thus, notwithstanding the clear, causal relationship between the action of an identifiable actor that is one of its agents, the U.N. has refused to accept its legal, moral, and political responsibility for the resulting harm of the Cholera epidemic in Haiti.[96] Responsibility should not turn on whether an organization assents to jurisdiction or not.[97]

Indeed, numerous actors can be considered responsible for the release of the deadly Cholera epidemic in Haiti. First, the Nepalese military deployed personnel to Haiti using a problematic medical screening process, which failed to detect or prevent Cholera in the deployed troops and can be considered directly causally responsible for the transmission of Cholera into the population.[98] Additionally, the U.N. had inadequate sanitary facilities for treatment of waste at the camp and insufficient monitoring of its bases and contractors.[99] As such, the U.N. was either vicariously liable through its mission’s failure or more indirectly causally responsible for the Cholera epidemic by failing to provide adequate guidelines.[100] Also, a Haitian contractor disposed of waste improperly near the base and at the river[101] and is causally responsible for the resulting Cholera epidemic. In addition, the Haitian government did not have proper procedures in place to trigger an early warning system and, more generally, failed to provide a secure and safe system for providing drinking water.[102] As a result, the Haitian government is also causally responsible for the Cholera epidemic.

How is responsibility allocated amongst these various actors?[103] The most common answer is that no actor is held responsible.[104] An alternative would be to have only the state actors be jointly and severally responsible for the resulting harm irrespective of their own contributions. However, the law of responsibility does not allow for this possibility. Another is that one state actor is held responsible for the harm irrespective of the size of the individual contribution of the Haitian or Nepalese governments. Conduct is attributable to the Nepalese state under the law of responsibility because it was committed by an organ or agent of the government, as the military personnel were on the base. Alternatively, the Haitian government is responsible because it failed to exercise due diligence and take necessary measures to prevent harm. The analysis above illustrates the state-centric nature of allocating responsibility under the conventional paradigm.

The current proposals for international organizational responsibility contemplate making states responsible where they delegate authority to an international organization that then violates rights.[105] For one or more states to assume vicarious responsibility, when some actors were acting through international organizations, hardly seems satisfactory here. Penalizing states for delegations of authority to international organizations that result in international law violations does not sufficiently account for the independent actions of international institutions. Another proposal for responsibility of international organizations concerns situations of internationally wrongful acts where there is concerted action between international organizations or between international organizations and states.[106] This proposal also fails to capture the actions of the U.N. in Haiti. There is no evidence of a prior plan or agreement between the actors to introduce Cholera into Haiti. The failure to provide for cumulative but nonconcerted action by multiple actors potentially allows states, and especially nonstate actors, to engage in blame avoidance and blame shifting for harmful consequences of highly-infectious diseases and to shield themselves from responsibility.[107]

The Cholera epidemic in Haiti illustrates why the allocation of responsibility is critical for successful implementation of the right to health and for bridging the gap between law, policy, and reality. The traditional doctrine relies on a narrow conceptualization of causation and would lead to inappropriately discounting the role of actors that have contributed indirectly to the epidemic in Haiti. Under traditional principles, responsibility cannot be determined for some, and other actors would be judgment proof.[108] It is also not possible to bring an effective claim against the collective.

Due to the challenges discussed above, where massive violations result—like the avoidable deaths during the Cholera epidemic—injured parties will be without redress. The state-centric nature of the law of responsibility means that the legal requirements are not met for some actors implicated in the Cholera epidemic. One of the underlying principles of attributing responsibility is that every legal injury deserves a remedy to ensure justice to victims. The Cholera epidemic in Haiti indicates that much more needs to be done to reform how international actors are held responsible for highly-infectious diseases. The traditional framework of responsibility is inadequate because it only apportions blame to culpable actors narrowly defined and ignores broader conceptualizations of culpability. Also, if it is not possible to hold culpable actors responsible in clear cases of but-for and proximate causation for any resulting violations of public health, as occurred with the Cholera epidemic in Haiti, what happens when the lines of causation are even more fraught, as with the Ebola epidemic in West Africa?

2. Ebola & Allocating Responsibility.—Ebola is an infectious disease that manifests as a severe hemorrhagic fever, which is often fatal without proper clinical care, such as providing fluids and maintaining blood pressure and oxygen levels.[109] Because the early symptoms resemble common diseases like malaria, many do not realize they are infected and do not seek treatment at a hospital.[110] The virus is spread in humans through direct contact with broken skin, blood, bodily fluids, or contaminated objects, and possibly through sexual contact.[111] The full toll of the epidemic in West Africa is still being uncovered, with reports showing that Ebola can linger in survivors’ eyes, causing painful disease, cataracts, and potential blindness in the young and old.[112] Ebola first appeared in 1976 in separate outbreaks in South Sudan and the Democratic Republic of Congo.[113] Whatever the biological or ecological origin of the virus in West Africa, it was the sociopolitical and legal landscape that influenced whether the virus would lead to a couple of isolated cases or become a full-scale outbreak.[114] This subsection seeks to foreground the indirect factors—the human-made laws, policies, actions, and omissions that gave rise to the Ebola epidemic. It does so to expose the fallacy of infectious diseases as purely biological or naturally occurring events[115] by focusing on one of the many factors that contributed to the spread of the epidemic.[116] This subsection illuminates the role of “structural adjustment” reforms in undermining already compromised health systems in the subregion.[117]

Structural adjustment refers to the loan conditionalities imposed by the International Monetary Fund (IMF) and the World Bank. Structural adjustment aims to contract certain areas of the formal sector with an eye towards improving specific macroeconomic indicators.[118] The structural adjustment of an economy occurs through compliance with the conditions embedded within the terms of loans, like reducing budget deficits, devaluing currency, reducing domestic credit expansion, freeing controlled prices and interest rates, reducing trade barriers, and privatizing state enterprises.[119] These well-known austerity measures aim to cut budget deficits and improve the balance of payments, which often entails budget ceilings and wage caps.[120] The IMF has been active in West Africa for decades with its structural adjustment programs. For example, its first loan in Liberia began in 1963,[121] and since 1984, the IMF has given consistent support to Sierra Leone and Guinea.[122] The IMF’s structural adjustment programs prioritized short-term macroeconomic objectives over longer term investments in public health, and the result predictably hollowed out the flailing health sector.[123] For example, an independent evaluation of the IMF’s structural adjustment programs surveyed twenty-nine countries in sub-Saharan Africa between 1999 and 2005 and found that 37% of all annual aid increases were diverted to beefing up currency reserves, with another 37% going to repay debts in line with the dictates of structural adjustment—leaving only 27% for health and other pressing developmental needs.[124]

Irrespective of the labeling that the IMF used to describe its programs—from structural adjustment, to good governance, to poverty reduction—the underlying logic and macroeconomic policies remained the same.[125] Although the IMF has attempted to respond to the criticism leveled against it, it continues to prioritize “macroeconomic stability” above all else.[126] Indeed, prior to the Ebola outbreak, although all three countries had successfully met the IMF’s macroeconomic policy prescriptions, they all failed to meet targets for social spending, including health.[127] This would render the health systems in Liberia, Sierra Leone, and Guinea ill-equipped to arrest the spread of Ebola when the outbreak began in 2014.

Moreover, to keep government spending low, the IMF placed limitations on public-sector wages, which meant money to employ and remunerate doctors, nurses, and other health care professionals was limited.[128] As health care employment opportunities lessened, health care quality and a capable health care workforce concomitantly decreased.[129] Additionally, depressed wages in the public health system contributed to the brain-drain problem in the health sector (where indigenous talent leaves for greener, more prosperous pastures).[130] For instance, even before the Ebola epidemic began in 2014, in a survey of health care workers for every 1,000 persons found, Guinea could only count 0.097 doctors, Liberia, 0.023, and Sierra Leone, 0.024.[131] In Sierra Leone, the structural adjustment policies of the IMF between 1995 and 1996 required the reduction of public employment, which resulted in the retrenchment of 28% of governmental employees, with limits on wages continuing into the 2000s.[132] This directly affected health, as a study provided by the WHO shows a reduction in community health workers from 0.11 per 1,000 population in 2004 to 0.02 in 2008.[133] While it is impossible to isolate how much of the lack of health workers was caused by structural adjustment, it seems plausible that these reform policies were at least a substantial factor in producing this result.[134] Accordingly, the effect of structural adjustment reforms—by insisting on cuts in health spending to manage public expenditures—was detrimental to the supply of health services. Thus, when the outbreak occurred in 2014, not enough trained health workers were readily available to help combat the spread of Ebola.

Additionally, structural adjustment reforms also had a negative impact on the demand for health services by reducing household income, leaving people with less money for health. Due to the IMF’s structural adjustment policies, public health was transformed into a “commodity and an individual responsibility.[135] For example, in Sierra Leone, despite the government’s introduction of a free health care initiative, health care providers continued to charge fees for services, thereby limiting access.[136] It was likely influenced by the IMF’s admonition to “carefully assess the fiscal implications” of providing free health care services.[137] Indeed, studies have shown that the IMF’s policies have slowed down improvements in, or worsened, the health status of people in countries implementing them.[138] Given this, it is not difficult to see how the depletion of investment in health services contributed towards higher incidences of Ebola in the subregion. In the 2000s in Guinea, the IMF promoted fiscal and administrative decentralization, which made it difficult to plan a coordinated response to Ebola. Five years after Guinea complied with IMF dictates to transfer budgetary responsibilities from the central government to the local level,[139] an IMF mission to the country found governance problems, ineffective decentralization, and deterioration of the quality of health-service delivery.[140] While the IMF programs cannot be blamed entirely for this result, it nonetheless indicates that the collective effects of the structural adjustment programs potentially made survival from an epidemic in the impacted countries less likely. IMF programs made it more likely that individuals would rely on communities of care as opposed to public health systems, which in turn impeded the ability to have a coordinated approach to Ebola.

The IMF belatedly recognized the connection between its policies and the outbreak. IMF Director Christine Lagarde said at a meeting on Ebola in 2014, “It is good to increase the fiscal deficit when it’s a matter of curing the people, of taking the precautions to actually try to contain the disease. The IMF doesn’t say that very often.”[141] Indeed, the IMF had been requiring the exact opposite for decades preceding.

The IMF’s structural adjustment programs are illustrative of how action by international institutions can facilitate epidemics and how the temporal distance between the initial action and the resulting outbreak can lead to the disremembering of structural factors. For example, the Ebola epidemic in West Africa was the result of historical vulnerability from slavery, colonialism, neocolonialism, bad governance, and neoliberal reform policies like structural adjustment, amongst others. When institutions like the IMF contribute to indivisible harms as witnessed with Ebola, the dominant paradigm of responsibility is unable to provide redress and fails to capture these violations.

The conventional law of responsibility depends on a clearly identifiable actor who acts to produce injury.[142] However, the traditional approach typically fails to capture the harms caused by highly-infectious diseases due to the multiplicity of actors causally contributing directly and indirectly to the harm. Thus, the increased rates of morbidity and illness from infectious diseases like Ebola are unaccounted for. This makes it incredibly “difficult to secure effective legal measures for prevention, restitution, and redress”[143] for epidemics using the traditional framework of responsibility.

The law of responsibility is inept. It privileges the status quo and directs attention towards individual claims against specific actors for identifiable proximate harms and away from broader conceptualizations and concepts of shared responsibility.[144] It is inadequate for combating highly-infectious diseases because it focuses on state actors often to the exclusion of international organizations and other important nonstate actors. The analysis above indicates that a reexamination of the current doctrine of responsibility is needed more generally and especially as applied to combating highly-infectious diseases.


C. Reconceptualizing Responsibility: Whither the Responsibility to Protect

A rival principle that challenges the traditional view of state responsibility is the emerging norm of the responsibility to protect. This section examines what the norm entails and demonstrates why R2P offers an incomplete vision for reconceptualizing responsibility. The foundational principles of R2P provide that the state has the primary responsibility for protecting its people, but if a state is unwilling or unable to stop or prevent war crimes, genocide, and crimes against humanity, the principle of nonintervention in the internal affairs of states is to yield to the international responsibility to protect.[145] R2P is not settled law, and the extent to which it influences state behavior is sporadic at best.[146]

The U.N. Secretary General has indicated that there are three components of implementing R2P. Pillar I emphasizes that states have the primary responsibility to protect their own populations and suggests ways states can improve their capacity to do so.[147] Pillar II focuses on the responsibility of the international community to assist states in building capacity to protect their populations through development assistance, preventative deployments, rule-of-law aid, and similar peaceful measures.[148] Lastly, Pillar III stresses the responsibility of the international community to take timely and decisive action to prevent genocide, ethnic cleansing, war crimes, and crimes against humanity when a state is manifestly failing to protect its population.[149] Pillar III has effectively overshadowed Pillar II in practice. It also seems useless to extricate Pillar II from the rest of the doctrine because, if the objective is to assist states in building capacity, this could be achieved without the rest of R2P’s baggage.

Most of the debate on R2P centers less on what satisfies the duty to cooperate[150] and more on fears of its misapplication. The International Law Commission states that cooperation in R2P situations can take place through international organizations or be noninstitutionalized.[151] The institutionalized form of R2P is most often affiliated with the United Nations Security Council (Council)[152] or regional organizations. The role of the Council in implementing R2P[153] must be approached with trepidation as it could improperly exceed its mandate and potentially violate respect for state sovereignty. The noninstitutionalized form of R2P is also potentially subject to misuse by powerful states, since they can use R2P as a pretext for military intervention and to sustain global hierarchies.[154] Because R2P assigns duties to all outside states with little differentiation, it faces some of the same challenges with undistributed duties not being discharged that the law of responsibility does.

In sum, R2P offers an insufficient shift in reconceptualizing responsibility. As one of the most radical challenges to traditional principles of responsibility, it still falls into predictable hierarchies that privilege civil and political rights over and above economic and social rights. R2P is a modest improvement on the completely state-centric nature of the law of responsibility because it hints at responsibility beyond the state. However, R2P embeds state-centricity in other ways, for example, by pretending as if the conditions that give rise to crimes against humanity, war crimes, and genocide in any given state are divorced from international actors. It also fails to adequately distribute responsibility and comes with the additional danger of exploitation and advancing imperialistic tendencies of powerful states. The next subsection demonstrates why R2P is flawed as applied to combating highly-infectious diseases.


The Inappositeness of the Responsibility to Protect for Combating Epidemics.—R2P’s original conceptualization was much broader. For example, the International Commission on Intervention and State Sovereignty argued that it included protection from starvation.[155] Some scholars argue for a return to first principles, beyond R2P’s historical association with crimes against humanity, war crimes, and genocide.[156] This expanded approach would theoretically allow for R2P to have broader significance and address serious socioeconomic violations caused by structural processes.[157] This author is unconvinced that R2P can be rehabilitated or expanded in meaningful ways.[158]

First, it does not appear that R2P has any real utility for responding to highly-infectious diseases. For example, applying the R2P framework to epidemics would mean that each state would be expected to reduce the number of highly-infectious diseases within its borders; the international community would be expected to assist states towards meeting its goals; and where a state or other actors are unable or unwilling to do their part toward fulfilling or supporting a state’s duty to protect its population from

highly-infectious diseases,[159] the state and/‌or other actors could be subject to serious consequences. However, states are not self-sufficient, and the distribution of highly-infectious diseases is fundamentally conditioned in part by transnational actors and global institutions.[160] Accordingly, an expanded conceptualization of R2P would still problematically place primary responsibility on countries that are the least equipped to combat epidemics effectively.

Thus, for R2P to have any relevance for altering the conditions that led to underlying structural issues,[161] it must be permanently divorced from the blunt coercive measures utilized under it. Given R2P’s primary association with the use of force,[162] its value in combating epidemics is inherently suspect. Indeed, the use of force to arrest epidemics would lead to more damaging socioeconomic consequences.[163] Allowing for potentially selective military enforcement is a precarious method for preventing the spread of diseases. And, even with a Council authorization, military intervention would still only aggravate direct and structural harms. Changing the underlying systems, institutions, laws, and policies that facilitate epidemics would not be furthered by allowing for military intervention.

Additionally, economic sanctions as a means of addressing highly-infectious diseases and global health inequities also seem particularly unfitting. Economic isolation would only exacerbate the problems of countries with epidemics in attempting to marshal resources to provide treatment and to prevent further contagion.[164] Such measures will prove counterproductive and increase tensions at a time when greater international cooperation is needed.

Problematically, there is no limiting principle within R2P that would prevent the Council or other international actors from utilizing one of these unsuitable means to implement R2P as opposed to more pacific measures. Accordingly, R2P might allow for sovereignty incursions whether states in the Global South want or need health assistance and could open the floodgates for pretextual interventions.[165]

Finally, because the international community has not been able to successfully deal with problems of direct mass personal violence in R2P situations, it may be even less equipped and willing to address problems presented by epidemics. Given the above considerations, R2P is patently unsuitable for addressing challenges posed by pandemics. Accordingly, the next Part demonstrates why the CBDR framework offers a more compelling vision of shared responsibility and why it will more effectively address epidemics than extant regimes.


III. Common but Differentiated Responsibility and Epidemics


A. Understanding Common but Differentiated Responsibility

1. CBDR in Theory.—CBDR reflects the effort to achieve equity between richer countries in the Global North and poorer states in the Global South.[166] Under it, richer countries agree to take on higher obligations to combat environmental concerns to reflect consumption and production patterns, as well as the unequal distributions of risks that result in more devastating environmental consequences for poorer countries.[167] It is based in part on the principle of solidarity[168] and reflects the role of the Global South in shaping international law by demanding more equitable rules.[169]

The first step in understanding the CBDR framework requires clarity on the meaning of “common.” The principle of CBDR in international environmental law evolved from resources that were considered part of the “common heritage” or of common concern to humans.[170] The rhetoric of “common interest,” “common concern,” and “common heritage of mankind” was originally conceived to deal with deep seabed resources and issues of the utilization of outer space.[171] The aim of these treaties was to further conservation and protection efforts.[172] The use of “common” in the CBDR framework suggests that certain resources “affect and are affected by every nation on earth.”[173]

The second part of understanding the CBDR framework necessitates precision on the meaning of “differentiated responsibility.” This element of CBDR in international environmental law focuses on a range of different burden-sharing arrangements that take into account each nation’s particular circumstances,[174] especially “each State’s contribution to the evolution of a particular problem and its ability to prevent, reduce and control the threat.[175] CBDR focuses on the state’s historical contributions to environmental degradation and takes this into account when fashioning legal commitments.[176] The idea of differentiated responsibilities in environmental law was aimed at promoting “substantive equality between developing and developed States within a regime, rather than mere formal equality.”[177]


2. CBDR in Practice.—CBDR reflects the belief that while all states are responsible for global environmental problems like ozone depletion, some states are more responsible than others.[178] In light of this principle, countries in the Global North have committed to joint projects in developing countries to assist with issues like emissions reductions.[179] Developed countries have also been asked “to take the lead” in mobilizing finance for tackling environmental challenges.[180] These initiatives recognize that developing countries will need major assistance from developed countries if they are to mitigate the detrimental effects of ozone depletion and climate change.

CBDR in international environmental law is premised on the logic that the countries responsible for polluting the global commons should utilize the resources gained from those activities and have primary responsibility for cleaning up the environment, as well as help other countries adapt clean-development technologies.[181] For example, the most recent climate-change-mitigation effort, the Paris Agreement, acknowledges the specific needs and concerns of developing countries arising from implementation measures.[182] Under the Paris Agreement, each party makes self-determined emissions reductions with climate change adaptation plans that are to be in place by 2020.[183] CBDR is still reflected in many aspects of the treaty, from the preamble[184] to the differentiation between developing and developed countries in the Annex, as well as provisions that stress the importance of financing and technology transfer for developing nations.[185]

The principle of CBDR is also reflected in the ozone protection regime. Important developing countries like China and India were initially not members of the Montreal Protocol on Substances that Deplete the Ozone Layer.[186] They argued that they had not caused the problem and were unwilling to forgo using cheaper products with ozone-depleting substances, or to use more expensive substitutes to enrich the industry responsible for the problem.[187] Legal obligations in conventions reflecting CBDR are not just based on differentiated mitigation actions for developing and developed states.[188] For example, the London Amendment to the Montreal Protocol of 1991 incorporates the principle of CBDR through the creation of a Multilateral Fund, which provided for differing contributions to adaptation measures for developed and developing states.[189] The ozone treaty regime reflects the equity arguments made by developing countries and provides additional incentives for developing countries to ratify and comply with their obligations under the treaty. The ozone regime is one of the biggest success stories in international law. Since 2005, the ozone hole has been shrinking.[190] By 2014, the ozone treaties had resulted in the phasing out of 98% of all ozone-depleting substances.[191] Scientists anticipate that the hole in the ozone will close completely by around 2060.[192]

The principle of CBDR has met with mixed results in mitigating climate change but has been usefully applied to address ozone depletion in practice. While the ozone regime has served to mostly eliminate the production and use of ozone-depleting substances, the climate-change regime has produced only modest steps at stabilizing greenhouse gases. However, climate change is a vastly more complex problem than ozone depletion. It involves virtually every form of human activity that contributes to greenhouse gases and presents more difficult distributional and equity issues than ozone depletion. Overall, the analysis above indicates that CBDR has continued vitality.


B. Expanding the Common but Differentiated Responsibility Framework

This section develops and expands the theory underlying the framework of CBDR. It applies this framework to the Cholera and Ebola epidemics, which in turn yields important implications for the theory of CBDR. This section fleshes out aspects of the CBDR framework that are undertheorized. It does this by drawing on concepts of criminal law and tort law, as well as corrective justice and remedies. The below subsections set out the case for expanding “common” and the case for expanding “differentiation” based on need, culpability, and capacity within the CBDR framework.

1. The Case for Expanding “Common.”—The first element of CBDR, “common,” conventionally describes the shared obligations of two or more states towards the protection of an environmental resource.[193] But, there is no reason why “common” could not apply to other resources that are shared, like global public health, either because the resource is not sufficiently under the control of a state, or is under the sovereign control of a state but subject to a common legal interest.[194] Indeed, the ordinary meaning of “common” highlights the public aspect of the term and defines it as “of or relating to a community at large.”[195] Similarly, legal definitions also indicate that, when used as an adjective, “common” is something that is “shared amongst several” or “owned by several jointly.”[196] Thus, we could conceive of the shared good of environmental protection being akin to the shared good of protection from disease.

Both environmental protection and protection from disease are global public goods[197] that are subject to common legal interests. Certainly, disease eradication has been identified as a “weakest link global public good” because international cooperation can be undermined by a single weak link or uncooperative actor.[198] Yet, disease eradication shares several similarities with aggregate effort public goods, like ozone layer protection, in that participation of all states is required for effective provision. Despite the different typology for conceptualizing disease eradication and ozone protection as public goods, the two areas have much more in common than the weakest-link and aggregate-effort public good categories indicate.[199] Namely, aggregate efforts like ozone fortification “can be undermined by weak links,” and for public goods like “disease eradication, efforts short of total success will still yield benefits, meaning that . . . aggregate effort matters.”[200]

States are beginning to recognize that highly-infectious diseases pose severe risks for the entire world.[201] States have also recently recognized that highly-infectious diseases present serious challenges to developmental goals.[202] In addition, states have acknowledged that certain “diseases and other emerging health challenges require a sustained international response.”[203] Stakeholders are also starting to identify the linkages between infectious disease and climate change given the anticipated escalating costs of addressing infectious diseases known to be climate sensitive, such as Cholera, malaria, Dengue fever, and other viral diseases.[204] Certainly, warmer weather linked with climate change allows mosquitos and other insects to breed and transmit diseases faster. This means that new diseases will show up in places that they have not been, like Zika, and that other established infectious diseases will continue to grow in places where they have been.[205] In the United States alone, the number of insect-borne illness cases that individuals reported to the Centers for Disease Control and Prevention tripled from 2004 to 2016.[206] The increase in the number of reported cases may simply reflect the increase in testing and reporting or the increase in jet travel that facilitates the easy transmission of diseases, but the influence of a warming climate on these trends cannot be easily discounted. Indeed, studies have shown that warmer weather is assisting the spread of infectious diseases in other wealthy countries as well.[207] When facing common risks in other contexts, states have recommended that all actors “cooperate in a spirit of global partnership.[208] Thus, a CBDR framework for highly-infectious diseases is a logical conceptual expansion and provides a method for addressing mutual risks posed by epidemics.

2. The Case for Expanding “Differentiation.”—The second element of CBDR is “but differentiated responsibility.” The plain meaning of “but” is “except for the fact,”[209] while the ordinary meaning of “differentiate” is “to mark or show a difference.”[210] Legal definitions of “responsibility” speak to “the obligation to answer for an act done, and to repair any injury it may have caused.”[211] Reading all the definitions of the component parts of CBDR together yields: something relating to a community at large or that is shared amongst several, except for the fact to mark or show a difference in the obligation to answer for an act done, and to repair any injury it may have caused. Nothing warrants restricting this definition to the realm of international environmental law.[212] In fact, the second element of the principle of CBDR is reflected in many areas of international law. For example, under the General Agreement on Tariffs and Trade, the enabling clause inculcates a system of preferences wherein “parties may accord differential and more favourable treatment to developing countries, without according such treatment to other contracting parties.”[213] Additionally, the Agreement on Sanitary and Phytosanitary Measures allows developing countries to request time-limited exemptions from their obligations geared towards food safety and animal and plant health, and it requires developed countries to consider providing technical assistance to exporting countries in order to allow them to meet any standards set by the importing developed country.[214] Differential obligations are also found in the intellectual property regime to address public health problems posed by epidemic diseases. For example, the Doha Declaration reaffirms the commitment of countries in the Global North to provide incentives to corporations and other institutions to promote and encourage technology transfer to countries in the Global South.[215] The Declaration also allowed for the phasing in of obligations under the Trade-Related Aspects of Intellectual Property Rights Agreement[216] with respect to pharmaceutical products for the least-developed country members until January 1, 2016, without prejudice to their right to seek further extensions.[217] Consequently, the second element of the CBDR framework is already influential in many areas of law and is ripe for further development.

Undoubtedly, there are several norms underpinning the differentiated-responsibility element of CBDR that need elaboration. Particularly instructive is the Rio Declaration on the Environment and Development, which states that developed countries shall acknowledge the “special situation and needs of developing countries, particularly the least developed and those most environmentally vulnerable, [and that they] shall be given special priority.[218] The Declaration provides that:

In view of the different contributions to global environmental degradation, States have common but differentiated responsibilities. The developed countries acknowledge the responsibility that they bear in the international pursuit of sustainable development in view of the pressures their societies place on the global environment and of the technologies and financial resources they command.[219]

The Declaration mentions three distinct normative bases for differentiation: need, culpability, and capacity. The next subsections will take up and develop each axis of differentiation and make the case for expansion of the CBDR framework to global public health.

a. Differentiation Based on Need.—The first rationale for differentiation in the Rio Declaration distinguishes the needs of developing, the least developed, and vulnerable countries from developed countries.[220] Expanding this rationale of differentiation to combat highly-infectious diseases means there would be disparate levels of responsibility for addressing epidemics, which would correspond with varying levels of social, economic, and health needs.

Undeniably, need-based claims for differentiation are hardly new; much legal and philosophical ink has been spilled on claims grounded in the duty to rescue.[221] The normative justification for differentiation on this ground is straightforward—morally, we have a responsibility to help those in need. Need-based claims often run headfirst into the so-called slippery slope, in that vulnerable countries are faced with many needs, not just risks posed by epidemics. If need-based claims for differentiation were accepted, the practical implications for law-and-policy making in global public health would be substantial, but surmountable, as the status quo distribution of need is avoidable under a more just international order. Although the political appetite may be low, the effort to do so would be minimal. For example, a mere 0.1% of the gross national income of sixty-six high-income economies is all that would be needed to meet the core obligations of the right to health.[222] Certainly, eliminating deprivation globally is achievable collectively, as substantial improvements in the living conditions in the Global South are possible at small opportunity costs to those in the Global North.[223]

The countries where the Cholera and Ebola epidemics occurred certainly meet the criterion of need. In the aftermath of the conflicts in Guinea, Liberia, and Sierra Leone and before the 2010 earthquake in Haiti hit, many vital state institutions were nonexistent or significantly weakened.[224] The epidemics were able to wreak such havoc in large part because these are some of the poorest countries in the world.[225] For example, even though Liberia and Sierra Leone had some of the highest growth rates globally, the vast majority of people’s lived experiences were defined by continued or growing poverty prior to Ebola.[226] Liberia ranks 177 out of 188 countries on the U.N. Development Program’s Human Development Index (HDI)[227] for 2014, in front of Sierra Leone at 181 and Guinea at 182.[228] Comparatively, prior to the Cholera epidemic in Haiti in 2010, the HDI ranked Haiti 145 out of 169 countries.[229] The level of susceptibility in all four countries to infectious diseases when the outbreaks occurred was dismal. The percentage of public health expenditures relative to gross domestic product that all four countries spent on health prior to the epidemics paled in comparison to countries with the highest human development.[230] Examining the relative deprivation and susceptibility to outbreaks in all countries prior to the Cholera and Ebola epidemics reveals a key insight for the theory of CBDR. The CBDR framework must also consider relative health needs, that is, a determination of the resources (or lack thereof) to mitigate the risks from epidemics, as opposed to simply focusing on absolute need.

Differentiation based on need within the CBDR framework would mean that states, international organizations, and other nonstate actors would have a moral and undoubtedly contested legal duty to recognize and act upon the threats posed by epidemics like Cholera and Ebola. This legal duty as applied to highly-infectious diseases could be based in part on norms of international cooperation that already exist in international law. Arguably, the U.N. Charter requires member states to provide international assistance and cooperation. Under Article 56 of the Charter, members are “to take joint and separate action in cooperation with the Organization for the achievement of the purposes set forth in Article 55.”[231] And Article 55 provides that the U.N. shall promote “solutions of international economic, social, health, and related problems; and international cultural and educational cooperation.”[232] Article 55 also provides in relevant part that the U.N. should promote higher standards of living and conditions of economic and social progress and development as well as universal respect for and observance of human rights.[233] Reading these provisions together provides a basis to argue that states are obligated under the Charter to cooperate with the U.N. and other actors to prevent, detect, and arrest pandemics. Several scholars are of the view that the Charter does not legally empower the U.N. to force member states to aid.[234] That states are not subject to compulsion, however, does not mean that they are not under an obligation to act.

Notwithstanding the ostensible lack of binding obligations, there are promising recent developments that reflect the expanded CBDR approach. For instance, the Global Health Security Agenda was created in 2014 in the midst of the Ebola epidemic and endorsed by the Group of Seven Nations (G-7).[235] Its goal is to “advance a world safe and secure from infectious disease threats, to bring together nations from all over the world to make new, concrete commitments, and to elevate global health security as a national leaders-level priority.”[236] Membership in the GHSA is open to all countries, and currently nearly 50 nations are members,[237] along with international organizations like the WHO, the Economic Community of West African States, and the European Union, as well as nongovernmental stakeholders.[238] It is a completely voluntary initiative wherein countries endeavor to make commitments to prevent, detect, and respond to threats whether naturally occurring, deliberate, or accidental that arise from highly-infectious diseases. One of the key aspects is the external evaluation tool’s ability to highlight gaps and needs for current and prospective donors, as well as to inform and assist country-level planning and priority setting.[239]

The GHSA differentiates based on need. The countries most impacted by Ebola—Liberia, Sierra Leone, and Guinea—joined and have experienced improvement.[240] For example, during the Ebola epidemic in Sierra Leone in November of 2015, only 35% of health facilities reported to their respective districts.[241] By September 2016, with the help of the GHSA, this increased to 96% of health facilities.[242] Early indications similarly show the initiative’s impact in Liberia. Prior to the 2014 Ebola outbreak, Liberia had very few trained “disease detectives,” but with the initiative’s support at the end of 2016, it had approximately 115 trained “detectives” covering all fifteen counties and ninety-two health districts.[243] This progress will likely assist with early detection of epidemic diseases in the sub-region. The GHSA incorporates an important aspect of the CBDR framework.

Differentiating based on relative health needs makes intuitive sense because while public health risks are distributed across all nations, some nations are more needful of assistance than others and are especially vulnerable to epidemics. Differentiating responsibility based on need makes clear that the basis for obligations of international assistance and cooperation does not depend on whether an actor has contributed to the resulting harm. At the same time, meeting the global need required to address epidemic diseases requires more than the resources of any one state, as such obligations to cooperate must be shared and differentiated not only based on need[244] but also based on culpability and capacity. The next subsections take up both in turn.

b. Differentiation Based on Culpability.—The second rationale for differentiation in the Rio Declaration recognizes countries’ responsibility for different contributions to global environmental degradation.[245] Expanding this rationale to global public health affords a basis for differentiation based on an assessment of those who contributed to highly-infectious diseases and calls for a concomitant apportionment of responsibility to repair the harm caused. Under a CBDR framework to combat epidemics, dissimilar levels of responsibility would be allocated based on the culpability of actors.

Under a culpability analysis, the emphasis changes from a focus on the obligations to succor to the conditions that created the epidemic. Differentiating based on culpability would not leave states solely responsible for addressing health inequities that exist, in part because of the structuring of the international system like other frameworks.[246] CBDR would necessitate determining the culpability of international actors in facilitating global health inequities. This is particularly important when one considers that a fundamental norm that is being violated with epidemic diseases is the failure to comply with an obligation to assist and cooperate internationally.[247] Accordingly, a culpability analysis under CBDR should look to such factors like the power an actor wields to influence international affairs and its ability or inability to shape the international trade, investment, finance, intellectual property, development, and global public health regimes, among others, that create conditions for epidemics to spread.

The culpability analysis should be wide-ranging. As such, it cannot be limited to situations where it is the actor’s purpose or conscious objective to perform an action that causes harm. Additionally, it cannot simply contemplate situations where an actor has knowledge that its conduct will cause a result, but the actor is indifferent to that result. Nor can the analysis be restricted to reckless actors that are aware of the strong possibility that their behavior will produce harm but discount the risks and proceed. A thorough culpability analysis must also account for situations of negligence where the actor is unaware and inadvertently creates a substantial and unjustifiable risk of harm. Objectively, negligent actors are deemed responsible because they fail to perceive risks, and their failure is a gross deviation from the standard of care that a reasonable actor in the same situation would exercise. A culpability analysis that accounts for the above mental states will sufficiently capture direct and indirect action witnessed with structural harms like epidemics.

Notably, the broad culpability analysis proposed herein is not a method for imposing a form of strict liability that merely requires an action and a harmful result. Strict liability is an exceptional form of responsibility domestically and internationally, reserved for actors who act without a culpable mental state. Strict liability may seem attractive because it is a method of ensuring that an individual actor’s behavior complies with the law and causes no harm to others. But it is unduly harsh and runs against the main purpose of the framework by allocating responsibility for every harm without distinction. Embedded within differentiating responsibility based on culpability is the implicit understanding that more culpable or blameworthy actors should be assigned more responsibility, and less blameworthy actors should be assigned less responsibility. Thus, strict liability is inapposite because it fails to distinguish between levels of culpability.

There may still be trepidation that increasing culpability in this manner may create perverse disincentives for actors to render voluntary assistance or consent to more robust responsibility norms. However, the conclusion that a more wide-ranging conception of culpability should not be imposed does not follow from this concern. That is, society may be better off when more care is taken in the provision of public benefits like aid.[248] Accordingly, an expanded CBDR framework that causes negligent and other culpable actors to internalize the detrimental effects of external costs imposed would be better overall for society because it would incentivize more careful policies and actions.

The following subsections address two related issues: the need to account for the multiplicity of actors causing an epidemic and the need to account for historical culpability.

i. Culpability and Too Many Hands.—CBDR must consider the multiplicity of actors that may or may not act in concert to produce an epidemic. Instances of concerted and independent but cumulative action are termed “the problem of too many hands” to characterize the difficulty that arises when too many actors are involved in the process that caused the harm.[249] The problem of “too many hands” may also lead to challenges in identifying what actor is responsible for what due to lack of information or knowledge about a given situation.[250]

A narrow reading of causation would stop at the following inquiry: if the actor refrained from action, would the result have occurred anyway? However, causation so narrowly understood cannot offer the primary basis for attributing responsibility under this framework, especially because epidemics involve structural causes. Due to overdetermination, different questions apply than the traditional but-for test. Instead, the inquiry should consider the following:

(1) whether the actors’ actions were a substantial factor in producing the result, regardless of whether the outcome might have occurred anyway;

(2) whether the actors’ actions hastened the result; or

(3) whether the actors’ actions make survival less likely as a result.[251]

These queries are important because without examining them one would tend to stop at the first-level question—whether the result would have occurred but for the actors’ actions.

The avoidable deaths and the infringement of the right to health that took place during the Cholera epidemic were the result of cumulative action from too many hands.[252] If the traditional but-for test is used, it appears the outcome would have occurred regardless of most actors’ actions. Such a causal analysis would consider the Nepalese government for the actions of its military personnel, the U.N. for insufficient monitoring of its bases and contractors, the Haitian contractor for disposing of waste improperly near the base, and the Haitian government for failing to provide a safe system for providing drinking water. Under a superficial but-for analysis, perhaps only the Nepalese government is determined to be the but-for cause. The substantial actions of the U.N., Haitian government, and contractor seemingly made no difference to the resulting epidemic. That analysis would elide the realities of highly-infectious diseases. Instead, considering whether the above actors’ actions were a substantial factor in producing or hastening the result, or made survival less likely, regardless of whether the outcome might have occurred anyway, are more appropriate inquiries. Because epidemic diseases are characterized by overdetermination, it is critical to delve deeper than when ordinarily conceptualizing causation. Failure to ask the right queries may lead to inaccuracies in identifying what actors are responsible.[253] Similarly, simply focusing on the bad governance of countries or the recent history of conflicts in the West African subregion may obscure the role of international actors who championed neoliberal reform policies like structural adjustment, which contributed to the Ebola epidemic amongst others.[254] This legacy, concomitant with narrow post-conflict reconstruction efforts, combined to marginalize the health sector and undermine state capacity to respond to epidemic diseases.[255]

When determining responsibility, causation cannot be established if the result is so remote that it makes holding the actor accountable illegitimate.[256] The requirement of a direct causal link that is foreseeable or proximate to hold an actor responsible for an injury is a fundamental principle of international law.[257] Direct factors that should be relevant under an expanded CBDR framework include the contribution that an actor has made to the emergence of an epidemic. A thorough culpability analysis also considers the direct actions or omissions—be they international or internal with extraterritorial effect—that had reasonably foreseeable consequences—that resulted in an epidemic. For instance, it was clearly foreseeable that Cholera would result from the Nepalese government’s failure to properly screen its troops for Cholera before deployment, the U.N.’s inadequate supervision of contractors and insufficient monitoring at its base, the Haitian contractor’s improper disposal of waste, and the Haitian government’s failure to provide safe drinking water. Accordingly, it is fair to find the above actors as proximate causes for Cholera in Haiti and hold them responsible. The broader conceptualization of culpability articulated above allows for responsibility to be attributed to multiple actors.

ii. Lengthening the Historical Gaze of Culpability.—The CBDR framework must also necessarily lengthen the causal gaze temporally to fully account for historical harms, as opposed to pretending that the status quo distribution of highly-infectious diseases is simply due to erratic nature or bad luck. This approach would assign contemporary obligations not only because of today’s harms but also based on historical responsibility for past exploitation, as well as the persistence of the deprivation of the right to health. “While undeniably the spread of [epidemics] is due to a combination of domestic factors,” both current and historical, “the tendency has been to focus almost exclusively on local actors and [more contemporary] factors as a way to distance, differentiate, and other the spread of disease.”[258]

This subsection demonstrates how international actors are historically responsible for the vulnerability of the West African subregion that enabled the spread of Ebola.[259] Following the implementation of structural adjustment programs beginning in the 1980s, NGOs overtook most of the basic welfare functions of public health provision.[260] The beleaguered health systems enabled by structural adjustment were further degenerated following conflicts in the subregion. U.N. agencies, donor countries, and several international NGOs spearheaded the post-conflict recovery process in the subregion in the 2000s. They neglected restructuring the economic and social sectors in the subregion, which rendered already fragile countries ill-equipped to deal with Ebola and indirectly facilitated its spread. The United Nations missions in Liberia and in Sierra Leone led the loose coalition of organizations, which became responsible for managing the state and the health care sector.[261]

In many ways, this network voluntarily assumed care and functioned as the de facto government during post-conflict reconstruction. The fragility of this system of health care provision was apparent in 2007 when Doctors Without Borders left Liberia following the conflict. The lack of the vital services they provided resulted in the immediate closure of regional and urban hospitals.[262] This, concomitant with the closure of thirty NGO-run clinics in the country, undermined the already teetering system.[263] Following the conflicts, aid organizations delivered more and more services to the poor because some of the governments in the subregion were shrinking their spending on public health.[264] This meant that prior to the epidemic, public health facilities were regarded as places to be avoided and even resisted in the subregion.[265]

This fractured system of health care delivery created conditions that facilitated Ebola’s spread by accelerating the harm caused by the virus and/‌or reducing the likelihood of survival due to the lack of resilient health systems. The counterargument is that one can never know what would have happened if international actors had not intervened in the subregion. On this view, it is possible the epidemic might have been much worse but for structural adjustment or post-conflict reconstruction efforts. It is futile to attempt to disprove a counterfactual given the impossibility of knowing what would occur in this alternative universe and the inability of conducting a social experiment. More importantly, it seems clear that these interventions were at least substantial factors in producing the increased susceptibility to Ebola in the subregion and contributing to serious adverse consequences.

A crucial theoretical insight gleaned from the analysis above is that epidemics require more than simply a tort- or criminal-law evaluation of causation. Accordingly, the theoretical framework developed herein considers a global historical perspective, as well as moral and political evaluations of responsibility.[266] A nonexhaustive list of factors that should be considered in determining historical responsibility includes whether the harmful effects of past actions are traceable to current epidemics and/‌or whether the external actor gained unjust enrichment or benefit as the result of its past misdeeds.

Unsurprisingly, actors in the Global South will be the most vocal proponents of historical responsibility as a ground of differentiating culpability,[267] while actors in the Global North will tend to be the most hostile or ambivalent to it. There are numerous studies that have demonstrated the long-term detrimental consequences of the legacies of slavery and colonialism on the current economic performance and position of countries in the Global South.[268] For actors in the Global South, the way things are—the status quo—remains the key issue.[269] While in practice former colonial powers tend to direct international assistance towards former colonial territories,[270] it is not evident that this is out of a sense of historical responsibility for the position of former colonies. A common argument against claims of corrective justice is that the actors of today should not be held responsible for the sins of their predecessors. However, history must be owned. As far as historical responsibility can be traced to a common lineage, the bearers of that lineage must face the “future in the shadow of the collective past.”[271]

To the extent that more backward-looking arguments for differentiating based on historical culpability are likely to meet resistance, a more forward-looking approach might be more appealing. The alternative normative basis for differentiation based on historical responsibility would be to deter actors from engaging in harmful action in the future. Normative support can be located in the principle that actors should not benefit from their wrongdoing and should compensate those that have been harmed as a result of their actions.[272] It may be easy for actors in the Global North to assert that bygones should be bygones when they continue to benefit from those bygones, while the detrimental consequences are experienced primarily elsewhere in the Global South. For example, countries in the industrialized North have contributed to huge disparities in historic emissions, which has led to substantial environmental degradation that is forecasted to increase if the current rate of emissions continues. The damage from a warming climate includes the increase in epidemics, as well as the exacerbation of already established infectious diseases. It is unjust for actors to benefit from the production and consumption of greenhouse gases and then diffuse the external harms. While the increased incidence of epidemics affects both industrialized and developing states, the detrimental consequences of these diseases will be more severe in the Global South. If the objective is to contribute to global justice,[273] then we must create proper incentives and disincentives for actors such that they do not benefit from unjust enrichment.[274] In some sense, historical responsibility as a basis for differentiation requires that actors internalize the detrimental effects that they impose on others.[275] A deterrence rationale posits that it is only when actors take responsibility for their actions that future harm is likely to be avoided. Indeed, detrimental action without consequences does not usually get the incentives right.[276]

In sum, the framework developed herein accounts for direct, indirect, and multiple causal factors, as well as historical responsibility as bases for culpability. Differentiation based on culpability shifts the framework from what the vulnerable need to an analysis of the actors that caused the contagion. This section demonstrates why differentiating responsibility based on culpability is justified. However, under international human rights law, states are under a positive obligation to act towards the fulfillment of socioeconomic rights irrespective of issues of causation.[277] States also have a duty to address epidemics in global public health law, irrespective of a causal link. As such, a CBDR framework is warranted not only based on culpability but also based on capacity.

c. Differentiation Based on Capacity.—The final rationale for differentiation in the Rio Declaration disaggregates states with distinct capacities.[278] Expanding CBDR in this vein would necessitate diverse levels of responsibility based on capacity to combat highly-infectious diseases. Capacity as used in this framework refers to the ability of an actor to detect, prevent, and control communicable diseases, as well as assist others in accomplishing these objectives. Differentiating based on capacity is reflected in human rights and global public health law. The normative justification for differentiation of responsibilities based on capacity is intuitive—if we want a reduction in epidemics, then we should allocate responsibility to those that are best placed to do so.[279] Thus, under a CBDR approach, stakeholders in the Global North would be expected to take on special leadership roles based on their industrial development, experience with public health protection policies, greater wealth, technical expertise, and capacity to influence global decision-making.

An expanded CBDR framework should encapsulate prospective obligations to cooperate in the provision of international aid.[280] The International Covenant on Economic, Social and Cultural Rights stipulates that it is the obligation of all state parties, especially those with economic and technical capacity, to take steps towards the full realization of rights in the Covenant individually and through international assistance and cooperation.[281] The Committee responsible for interpreting this Covenant has emphasized that “States parties should recognize the essential role of international cooperation and comply with their commitment to take joint and separate action to achieve the full realization of the right to health.”[282] It asserts that states have an obligation subject to the availability of resources to “facilitate access to essential health facilities, goods and services in other countries, wherever possible, and [to] provide the necessary aid when required.”[283] Additionally, this Committee has found that states have a “joint and individual responsibility,” under international law, “to cooperate in providing disaster relief and humanitarian assistance in times of emergency.”[284] It has also found that states should contribute to this task to the maximum of their capacity, and should prioritize the provision of international medical aid, distribution and management of resources, and financial aid to the “most vulnerable or marginalized groups of the population.”[285] Thus, the enforcement body responsible for ensuring compliance with the Covenant on Economic Social and Cultural Rights explicitly recognizes parts of the CBDR framework, namely differentiation based on need and capacity. The following subsections address three related issues—the affected state’s capacity, external states’ capacity, and global capacity.

i. The Affected State’s Capacity.—Ideally, the affected state would have the most capacity to respond to epidemics. Global public health law provides states with a couple of years to make this ideal a reality. For example, the International Health Regulations require that each state party develop, strengthen, and maintain the capacity to detect, assess, notify, and report certain diseases within five years of its entry into force.[286] States not able to meet their capacity obligations must show good cause and, in exceptional circumstances, are to receive an extension of up to four years.[287] States are to develop capacities seemingly by fiat—“utiliz[ing] existing national structures and resources to meet their core capacity requirements.”[288] States also have specific public health response capacities to develop under the International Health Regulations (IHR). This includes rapidly determining the control measures to prevent the domestic and international spread of disease; providing support and logistical assistance; providing an efficient means of communication with relevant stakeholders; and establishing, operating, and maintaining a public health emergency response plan.[289] In 2005, the WHO found that health capacities were nowhere near “a path to timely implementation worldwide.”[290] By 2013, prior to the Ebola outbreak, no African state had fully implemented the IHR’s core capacity requirements.[291] These gaps in core capacities were especially pronounced in the Ebola-affected countries.[292]

Even in circumstances where states lack capacity, like with Ebola[293] or Cholera,[294] states still have obligations under human rights law. These obligations include monitoring the nonrealization of the right to health and devising strategies to promote the right,[295] as well as protecting persons within their jurisdictions from infringement of the right to health by third parties.[296] The determination of whether a state has taken all adequate and reasonable steps towards the progressive realization of the right to health includes the affected state seeking international cooperation to ensure the protection needed from highly-infectious diseases.[297] All of the affected governments sought international assistance for combating Cholera[298] and Ebola.[299] Accordingly, the Haitian, Liberian, Sierra Leonean, and Guinean states met their human rights obligations relating to epidemics. The determination regarding the affected state’s inability or unwillingness to take steps to prevent, treat, and control epidemics should not be overstated—its legal relevance goes to the affected state’s failure to meet its primary human rights obligations.[300] It is not dispositive as to the assignment of secondary duties to external states, which is to be determined by the failure of the rightsholders to exercise their rights.[301] In other words, “the principles governing the determination of responsibility are irrelevant for the determination of attribution of obligations.”[302]

ii. External Actors’ Capacity.—The responsibility of international actors to protect people from gross violations of human rights presented by pandemics is triggered by the manifest failure of national authorities to afford that protection, and not whether that failure is due to a government’s incapacity or unwillingness. International action to prevent, treat, and control epidemic diseases by actors other than the affected state, where required, is based on a subsidiary duty in circumstances where the primary duty bearer lacks capacity or is unwilling to fulfill its obligations.[303] This secondary duty is best understood as complementary to those of the rightsholder’s own state because any other reading would render meaningless the duty to cooperate in order to realize socioeconomic rights.[304]

Thus, the proper inquiry once we have attributed the obligation to cooperate to an external actor is whether it had the capacity to abide by this obligation.[305] If the external actor had the capacity to do so and failed to cooperate, then it can be held responsible. For example, the United States became the single largest government donor responding to Ebola by appropriating USD 5.4 billion in emergency funding, “the greatest amount of emergency funding ever provided by Congress for an international health emergency.[306] Almost all of this funding (USD 3.7 billion) was directed toward international activities for both the initial response and ongoing recovery and rebuilding efforts.[307] When the Zika epidemic occurred, a significant amount of U.S. Ebola assistance was clawed back and repurposed for Zika.[308] Despite the reduction of Ebola aid, this example is illustrative of an external state with capacity acting to cooperate towards combating a highly-infectious disease. It is emblematic of the special responsibility that economically developed states in the Global North have to assist poorer states in the Global South with epidemics.[309] Indeed, the International Covenant on Economic Social and Cultural Rights provides that special duties rest with actors that have more influence to conclude treaties and to make recommendations that can help to galvanize international action towards the achievement of socioeconomic rights.[310]

A preliminary objection to this special responsibility is the problem of “insatiable entitlements.” Differentiating based on capacity may require social spending “long past the point where additional spending will do much good” and under circumstances where a claim can never be satisfied.[311] This would present challenges where a state has not broadly secured the right to health at home but is expected to take steps to fulfill the right to health abroad. Nonetheless, highly-infectious diseases like Cholera and Ebola are not characterized by problems of too much spending. Limited resources for health, given other commitments, are already built into the current framework for socioeconomic rights. One way of addressing the “insatiable entitlements” problem is to require that any country that has realized the minimum essential levels of health domestically is then duty-bound to contribute to the realization of the same standard elsewhere before attempting to achieve the next highest attainable standard of health at home.[312] Another solution would place the duty earlier, requiring any state that has not met the minimum levels of health domestically to comply with its obligations to others elsewhere so long as there are, objectively, resources to do so, and no retrogression as to the rights of people within its territory occurs as a result of foreign assistance.[313]

iii. Global Capacity.—The treaty-body responsible for interpreting the Covenant on Economic, Social and Cultural Rights has stressed that because some diseases are “easily transmissible beyond the frontiers of a [s]tate, the international community has a collective responsibility to address this problem.”[314] Responsibility for remedying highly-infectious diseases through the CBDR framework should take the form of capacity building (research and information sharing), technical assistance (training and the provision of expertise), and financial and material assistance through special funds with contributions from members to help defray costs. Private foundations and public–private partnerships will also be instrumental in capacity-building efforts. These initiatives are especially needed where states lack the infrastructure necessary to address epidemics domestically.

The West African Ebola epidemic provides several illustrations of international actors demonstrating capacity to fulfill their collective responsibility. For example, the U.N.’s General Assembly called on “Member States, relevant United Nations bodies and the United Nations system to provide their full support to the United Nations Mission for Ebola Emergency Response,”[315] which was an attempt to coordinate the response to the epidemic through a unified international structure.[316] This was the institution’s first system-wide, emergency health mission. Its primary objective was to contain and prevent the spread of Ebola through case management and safe burial services, to treat infected individuals, and to provide services to affected communities.[317] The U.N. praised it as an innovative approach, which will likely increase “as the nature of global responses are reshaped to meet the complex challenges of this century.”[318]

During the peak of the Ebola epidemic, the Global Health Security Agenda was also created to facilitate collaborative capacity-building efforts.[319] These efforts were aimed at achieving specific targets tied to the core capacities under the International Health Regulations.[320] While the Regulations require the 196 state parties to cooperate to help build health capacities,[321] they do not articulate how this is to work in practice. The GHSA fills in this lacuna by creating a system for countries to address their commitments. There are eleven action packages that are designed to help build state capacity to prevent, detect, and respond to threats posed by highly-infectious diseases.[322] Under the GHSA, member countries can utilize a tool that helps to assess baseline national health security capacity. An action plan can then be tailored with a five-year target for states to meet, along with a set of indicators to measure progress and activities to support successful implementation.

The GHSA reflects the CBDR framework by differentiating based on need,[323] as well as capacity. Under it, member countries can reach their commitments by building capacity in their own nation, regionally, or globally. For example, the United States made a commitment to assist thirty-one countries and the Caribbean Community.[324] The United States has invested $1 billion in resources across seventeen of these countries, which need the most assistance with capacity building to detect and respond to future infectious disease outbreaks.[325] The United States’ rationale for participating is simple: “[T]he most effective and least expensive way to protect Americans from diseases and other health threats that begin abroad is to stop them before they spread to our borders.”[326] There is evidence suggesting that investments in promoting protective and primary care services in the Global South lead to large improvements in public health, generating benefits for other states like containment of epidemic diseases.[327] Additional donors, including the G-7 and G-20 leaders, as well as other donor countries and organizations, have provided a collective commitment to assist seventy-six countries to reach the capacities outlined in the International Health Regulations.[328] The GHSA is based on the view that “[g]lobal health security is a shared responsibility that cannot be achieved by a single actor or sector of government.”[329] However, neither the GHSA nor the Regulations determine how responsibility for capacity building should be allocated.[330] The CBDR framework can step in to fill in these gaps.

Significant theoretical insights for the framework can be drawn from the analysis above. A nonexhaustive list of the factors that should be considered in distinguishing the capacity of actors includes economic, technical, and technological capacities and available resources, but also influence and ability to impact international decision-making.[331] An additional factor that should be considered when differentiating capacity is the geographic distance of the external actor from the affected state.[332] Thus, relative capacity, as opposed to absolute capacity, to act will be crucial in determining responsibility.

This subsection makes the normative case for differentiating responsibility based on capacity. Differentiating based on capacity makes intuitive sense and is derived from human rights and global public health law. As with the other bases for differentiation examined above, this subsection maintains that capacity should not be considered in a vacuum when determining responsibility.


IV. Theoretical and Policy Implications of Expanding CBDR to Combat Epidemics

This Part resolves the inter- and intra-axis conflicts within the framework and explores the limits of diffusion, as well as the issues raised with operationalizing CBDR in hard and soft law.


A. Differentiating Within CBDR

1. Resolving Inter-Axis Conflicts.—It is not clear which axis of differentiation, if any, should be determinative when allocating responsibility. Does one have precedence over the others? For example, if capacity alone was determinative, then actors that are especially capable would carry more burden even if their involvement to address a given epidemic would lack legitimacy. Action to remedy the harm caused by the Cholera epidemic in Haiti would be viewed as more sociologically legitimate were it to be the U.N. paying financial compensation to victims as opposed to say the EU, which has a more tenuous causal link to the Cholera epidemic. Should culpability have superiority? It may be nonsensical to privilege one axis for all time and in all places. Yet, leaving the framework entirely indeterminate may lead to similar problems with allocating responsibility witnessed with the conventional law of state responsibility and R2P.

Accordingly, it is essential that further elaboration take place on whether the framework envisions a hierarchy. To this end, differentiating based on capacity must take precedence over other methods of differentiation. Differentiating based on capacity reflects obligations under human rights and global public health law. The positive duties that states have under both bodies of law to combat highly-infectious diseases are not based on a causal link or culpability. Differentiating based on culpability is secondary. The law of responsibility depends on a formal determination of culpability.[333] However, the CBDR framework does not, due to the numerous limitations for seeking redress internationally for violations experienced during epidemics through formal channels. For example, finding a venue with jurisdiction over actors implicated in pandemics that can exercise authority over relevant actors will be challenging in the best of circumstances. This is not to mention the difficulty that victims will have in recovering from respondents when seeking accountability for instances of shared responsibility. For instance, the contractor that improperly disposed of waste in Haiti likely did not have deep pockets, rendering it functionally judgment-proof for its share of responsibility. The Cholera epidemic in Haiti indicates that not all culpable actors will be capable. Additionally, this framework is not simply concerned with the allocation of responsibility as a theoretical matter. The objective is to further legal and institutional reform, rather than responsibility being purely punitive or even restorative. As such, culpability may be sufficient but not necessary for invoking CBDR.

The culpability framework envisioned herein is extensive, going beyond what is legally required. It is not evident that this expansion of culpability to account for direct, indirect, and multiple causal factors, as well as historical culpability, will gain traction with stakeholders given propensities for blame avoidance and blame shifting. Yet, the aim is to involve not only those held legally responsible but also a wider community of culpable actors. The framework is deeply concerned with the practicalities of combating highly-infectious diseases. Culpability as a secondary basis of differentiation reflects that normative judgment.

The status of each axis of differentiation in law helps to impose hierarchy on the CBDR framework. As such, differentiation based on need is ranked last due to the hyper-contested nature of these duties. The normative justification for differentiation based on need is morally clear and sound. However, the legal duty to render aid or rescue has not been widely accepted. Differentiating based on need is also logistically difficult since the need may be acute in many places. Indeed, what of situations where there is capacity to act to combat a highly-infectious disease, but the need is not yet acute? Differentiating based on need should not be used as a straitjacket to limit preventative actions that could forestall greater calamity. Such a restrictive view may undermine capacity-building efforts aimed at the development of a comprehensive public health system with the surveillance needed for epidemic prevention. For example, the Global Health Security Agenda provides a useful model that incorporates both need and capacity as means of differentiation, while singling out Ebola and other highly pathogenic infectious diseases as its focus.[334] As such, considering both the need to act, as well as another axis of differentiation will be instructive moving forward.

The above analysis presents significant insights for the theoretical framework. Mainly, all the bases of differentiation should be considered cumulatively together. To this end, actors with capacity will be allocated the most responsibility towards combating highly-infectious diseases, then actors with culpability. Actors with capacity and culpability are to direct their efforts at combating highly-infectious diseases where there are the greatest health needs. The more capacity and culpability actors have, the more responsibility for combating epidemics and vice versa. Additionally, need is the only form of differentiation that should be paired with another aspect of the framework in practice. This is because the details of which actor(s) has the most responsibility for a given epidemic and how inter-axis conflicts should be resolved will necessarily be context-dependent.

2. Resolving Intra-Axis Conflicts.—Another area for elaboration is how to resolve intra-axis conflicts within the framework. For example, it may be more socially desirable and legitimate for actors that have high capabilities (but are not the most capable globally) to act to remedy the harm caused by an epidemic disease. Otherwise, requiring action from only the most capable actors could reify geopolitical hierarchies in ways that allow for powerful actors to exercise oversight over programs aimed at highly-infectious diseases because they have more capacity than less powerful actors. This could serve to immunize more well-resourced actors from necessary health interventions, which would sustain a problematic role between countries in the Global South and Global North. To protect actors from unwarranted sovereignty incursions, the framework should require state consent for the provision of external assistance, with a stipulation that states cannot withhold consent without good cause.[335] There is a rich foreign-aid literature that discusses the mismatch between donor and recipient countries’ priorities, with aid supplanting local needs.[336] Donor governments and NGOs often direct aid to specific health projects and diseases through vertical projects like the Global Fund to Fight AIDS, Tuberculosis, and Malaria.[337] The role of the affected state in being able to articulate its needs and priorities is crucial.[338]

Consequently, the framework must be flexible and sensitive to local conditions and should not be applied in a rigid fashion. The framework must be cognizant of local priorities for combatting epidemics to formulate contextually appropriate responses. Much more experimentation needs to be done to determine how the framework would work in practice.


B. Diffusing CBDR to Combat Epidemics

The Limits of Diffusion.—The policy diffusion literature is vast.[339] Policy diffusion describes the phenomenon where policy choices made in one place are influenced by the policy choices made elsewhere,[340] which aptly characterizes the expansion of CBDR proposed herein. The policy diffusion literature cautions against the tendency to adopt policies from the “leaders even in the absence of evidence of the efficacy of those policies.”[341] Yet, there are several reasons to be cautiously optimistic about the value of CBDR as a policy matter.

First, disease eradication and ozone protection have similar problem-and-solution structures. One of the reasons for the ozone regime’s success is because it involved a handful of chemicals with a small number of producers located primarily in the U.S. and Europe. These chemical companies quickly developed reasonably priced substitutes for ozone-depleting substances because the ozone treaties banned their trade and required their phasing out.[342]

Similarly, disease eradication efforts should also target the producers. The global pharmaceutical market is expected to reach USD 1.3 trillion by 2020,[343] mostly from revenue generated and controlled from companies with headquarters in the Global North. The international intellectual property regime’s grant of monopoly rights to pharmaceuticals for twenty years[344] impedes pharmaceutical research and the development process for highly-infectious diseases that are not profitable. Pharmaceutical companies depend on charging monopoly prices to recover their investment in experimental drugs and technologies. This system does not incentivize the development of drugs to treat diseases that disproportionately impact people in the Global South.

Patent holders charge varying prices in different jurisdictions. The intellectual property regime places limits on parallel importation, which occurs where parties purchase goods in one state and then resell them in a second state without the patent holder’s consent.[345] This prevents countries in the Global South from accessing essential medicines at more affordable prices. The flexibilities in the intellectual property regime that allow for compulsory licensing are also insufficient.[346] Indeed, compulsory licensing is of little use to states with limited-to-no manufacturing capabilities to produce essential generic drugs at more affordable prices for their home markets.[347]

Changing the incentive structures for the research and development of drugs, as well as making generic and affordable versions of drugs more widely available, should aid efforts to eradicate highly-infectious diseases. The ozone regime indicates that changing the incentive structures prompted companies to develop cheaper substitutes, and with these substitutes, more countries stopped using ozone-depleting substances and traded in products that contained them. For example, the ozone treaty regime was initially focused on sharing information and scientific research.[348] Later, the obligations became more stringent with strict timetables for phasing out dependence on harmful ozone-depleting substances, as well as adding new substances to be phased out.[349] In the future, it is possible that the CBDR framework to combat highly-infectious diseases might develop along the same lines. Thus, there is reason to be enthusiastic about the potential efficacy of an expanded CBDR framework for combating epidemics.

Furthermore, CBDR may resonate more in global public health than in the international environmental regime. While environmental problems like climate change can be slow-moving with the most harmful effects predicted for generations from now, epidemic diseases tend to engender visceral fear in the present. Indeed, the tendency for some pandemics to take on a hyper-visible or spectacular quality means that an expanded CBDR approach may be especially useful for highly-infectious diseases. For example, the Global Health Security Agenda was shaped during the height of the Ebola epidemic not only to combat that disease but also other “highly pathogenic infectious diseases.”[350] The success of this initiative indicates that state practice is evolving to recognize the importance of a coordinated response to highly-infectious diseases. Thus, it is likely that the specter of other epidemics may similarly galvanize actors towards additional international action.


C. Operationalizing CBDR Utilizing Hard and Soft Law

1. Towards a Comprehensive Treaty Regime.—Concerns about the usefulness of CBDR may be heightened because its status as binding law is robustly debated.[351] Whether a customary international law norm[352] has formed on CBDR—separate from treaty law—or whether CBDR is a form of soft law that is nonbinding is irrelevant for this project. This Article draws inspiration from the under-theorized norm of CBDR in international environmental law and substantially develops it as a framework to inform progressive developments in global public health. Thus, clarity on the legal status of CBDR in international environmental law is unnecessary for its expansion, development, and application.

Although a CBDR framework for combating highly-infectious diseases might seem attractive on a theoretical level, skeptics may believe that it is impossible for this approach to be operationalized. First, there are few treaties regulating infectious diseases.[353] Also, states seem to have little appetite for additional treaty-making in global public health as compared to the international environmental regime.[354] In addition, due to the responsibility gaps discussed above,[355] many of the relevant nonstate actors would fall outside of any potential treaty regime and would not be bound by any such obligations.

Additionally, if the climate change regime’s negotiations on emissions levels are an indication, resulting decisions would be based on what was politically feasible and would have little to do with ethical or scientific considerations.[356] As such, treaty negotiations for an expanded CBDR framework would likely lead to a lowest common denominator not necessarily reflective of scientific best practices. It may be that linking the three bases of differentiation erects a substantial hurdle to subsequent legal adoption. Thus, one might expect any deliberations concerning diffusing the CBDR framework to privilege the status quo, given the international community’s limited willingness to mandate the redistribution of economic resources as a political matter. Accordingly, this Article does not advocate for the development of a treaty regime as an initial matter. However, because so much of the expanded CBDR framework is derived from existing law, a comprehensive treaty to implement the framework may not be necessary.

 

2. Towards a Soft-Law Regime.—A myriad of explanations exists as to why a soft-law regime makes sense as a starting place. First, operationalizing the framework through norms of conduct understood as legally nonbinding, or soft law, is achievable in the immediate future. Soft-law commitments may be more politically realistic because they do not require that all actors be incorporated into a single treaty. Soft law also does not necessarily have to accommodate the varying positions of different actors. When there are disagreements among states or uncertainties about how to achieve an agreed-upon goal, a comprehensive treaty regime could result in a race to the bottom to get the most parties on board, while a soft-law approach would not.

Moreover, soft-law commitments also offer significant advantages, such as flexibility and adaptability, when compared to comprehensive treaty regimes. Because the expanded CBDR framework is still in its infancy, a soft-law approach can act like a “trial balloon.” Soft law allows actors to maintain some freedom of action should situations change, since soft law can be easily amended and adapted to meet the needs of parties. For instance, soft law is far less cumbersome than the treaty amendment process. The treaty negotiation process can be long and unwieldy with lags in the development of implementation mechanisms. Yet, because soft law does not require formal domestic approval or ratification, discussions can be less contentious than treaty making, which requires the approval of domestic actors. Thus, soft-law commitments can develop quite rapidly and be used quickly to address highly-infectious diseases immediately.

The normative underpinnings of the CBDR framework have been expressed in soft law in the pledge to “leave no one behind,” the central theme of the 2030 Agenda, which seeks to place an obligation on everyone to reach those in situations of conflict, disaster, vulnerability, and risk.[357] CBDR has also been referenced in World Health Assembly committee meetings regarding the health effects of air pollution.[358] The most concrete instantiation of the CBDR framework is reflected in the Global Health Security Agenda, discussed above.[359] The GHSA has been operating since 2014 and capitalizes on the more participatory nature of soft law. Conventionally, formal treaty making and customary-law creation in international law are both state-centric enterprises. Soft law allows for the participation of nonstate actors, which would be highly desirable for addressing epidemics due to the significant role that nonstate actors play in global public health. The GHSA reflects soft law’s quick adaptability to respond to highly-infectious diseases, given its formation during the Ebola outbreak.

Also, soft law could work to create expectations that influence the actions of state and nonstate actors towards compliance. The main disadvantage presented by relying on soft law is that there could be less credible commitments by states since it is nonbinding. The framework can be shaped to reflect, and hopefully help form, a standard of appropriate conduct. Soft law would allow participants to determine what aspects of the framework are worth keeping and what needs to be modified before the expanded CBDR framework is completely memorialized.

The informality of soft law presents both an opportunity and a challenge for progressive development. Powerful actors can apply and enforce their preferred aspects of the framework to try to push the development of the law in one direction. This can occur even without a clear consensus on which aspects of the framework are favorable or unworkable. However, if the CBDR framework develops as soft law only, this may hinder the development of binding obligations because actors may be disincentivized to do more when they can do less. It is not evident that adopting a CBDR framework for combating epidemics would necessarily lead to that outcome. Indeed, it could also create expectations that impact the activities of actors in a way that fosters commitments without treaties, or treaty bodies, to coerce compliance.

Most optimistically, the CBDR framework could eventually induce meaningful change in the behavior of relevant stakeholders, which could lay the groundwork for a comprehensive treaty or the development of a customary international law obligation. Otherwise, at a minimum, compliance can be obtained through the framework via cooperative, interactive processes of justification, discourse, and persuasion. Whether the law will develop along the lines proposed is an open question. Notwithstanding, this Article demonstrates that an expanded CBDR framework for combating epidemics is worthy of progressive development in law and practice.


V. Conclusion

Epidemics are the result of the actions of multiple actors, which necessitates the comprehensive allocation of responsibility. Yet, the traditional framework for responsibility and the emerging norm of R2P are inadequate for addressing highly-infectious diseases. First, both the traditional principles of responsibility and R2P perpetuate the fallacy that states can cope on their own with structural problems, including the increased incidence of epidemics. Conventional approaches to responsibility are untenable for the realities of today’s world wherein responsibility needs to be distributed to several states and nonstate actors.[360] The traditional framework is also wanting due to its narrow conception of causality. Moreover, the traditional responsibility doctrine is too state-centric in terms of both accountholders and power wielders.[361] The state-centric nature of R2P similarly fails to recognize that the structural conditions that give rise to R2P situations are not divorced from the “international community.” R2P also privileges direct harms occasioned by civil and political violations over and above structural harms occasioned by socioeconomic violations. Moreover, both the traditional principles of responsibility and R2P fail to adequately distribute responsibility.

Given the limitations of the law of responsibility and R2P, this Article argues for a new vision of responsibility. It develops the theory underlying CBDR and makes the case for expansion of the framework to the challenges posed by epidemics. This Article articulates the distinctive normative bases for differentiating responsibilities based on need, culpability, and capacity. This framework better distributes responsibility and is less state-centric than rival norms of responsibility. It accounts for structural inequality in ways that other frameworks do not. It also does not reify the false hierarchy between civil and political rights and economic and social rights that exists in other areas. Moreover, it recognizes and accounts for the significant role of nonstate actors and provides a basis for holding such actors responsible, as opposed to pretending that only states are responsible for the increased incidence of epidemics. The CBDR framework is superior for dealing with highly-infectious diseases. It does not come with R2P’s baggage or the risks of the extraordinary responses utilized under R2P. Furthermore, the CBDR framework distributes responsibility far more comprehensively than extant regimes.

The expanded CBDR framework represents “part of a broader normative” push that “requires action on the part of those in a position to assist.[362] CBDR also hints at an emerging requirement for states to coordinate their efforts with each other to effectively “discharge their respective obligations to cooperate.”[363] The expanded CBDR framework is significant for the progressive development of global public health law. It also shifts the conceptualization of responsibility in fundamental ways.

There are valid concerns about diffusing this framework from addressing environmental problems to combating epidemics. States are not consistently adhering to capacity-building commitments in international environmental law. This generates uneasiness because it may be that they will be even less willing to address problems presented by epidemics through the framework. In the end, it may be that state and nonstate actors are roused to address highly-infectious diseases, not necessarily because of an acknowledgement of the need. Undeniably, the idea that actors should help others in need is not new.[364] Mobilization in the Global South has taken place for years to get actors in the Global North to address global inequities in health and other areas.

Moreover, actors may not even necessarily be motivated to action because of a recognition of culpability for an epidemic. This has certainly been witnessed with the U.N. in Haiti. Yet, motivation may similarly be lacking to combat epidemics even with the recognition of capacity to act and ameliorate harm. Certainly, actors in the Global North routinely reject an obligation to provide foreign assistance,[365] irrespective of capacity. For example, while states express support in principle for the notion that 0.7% of their GNI should routinely go towards development assistance, few states meet that goal.[366] Given this, there may be skepticism about the traction the expanded CBDR framework will have with relevant stakeholders.

Nonetheless, there is reason for cautious optimism about the prospects of success of this framework. CBDR is consistent with theoretical and existing foundations of law where responsibility is tethered to an actor’s conduct and relationship to the harm through culpability. However, the framework does not treat the culpability model as a legal straitjacket and envisions a broad understanding of causation—direct, indirect, and historical. Additionally, the framework differentiates based on capacity, which is derived from human rights and global public health law. It also draws on extralegal incentives, building on moral and political conceptualizations of responsibility towards those in need. In this way, the approach functions as a three-headed dragon, with multiple methods of galvanizing action to attack epidemics.

Through interactive processes, the norms underlying the CBDR framework can be invoked, interpreted, and elaborated in ways that generate pressure for compliance through soft law. Most hopefully, a CBDR approach to combating epidemics could be accepted as a normative framework that could serve as a precursor for the later creation of “hard” or binding international law.[367] The world is contending with the increasing incidence and severity of a wide range of highly-infectious diseases. The ease with which these diseases can spread in the wake of disasters and without makes it likely that state and nonstate action will be stimulated in this area out of a common self-interest. The GHSA is currently harnessing states’ shared self-interest to work to address the threats posed by highly-infectious diseases and is differentiating based on capacity and need. As such, a CBDR approach to epidemics is already functioning in practice. The findings from this Article will hopefully be used to help inform wider discussions in this area to aid with developing law and policy governing responsibility for, and risk reduction of, pandemic diseases.

  340. .Compare policy diffusion to legal transplants, which were originally defined as “the moving of a rule or a system of law from one country to another, or from one people to another.” Alan Watson, Legal Transplants: An Approach to Comparative Law 21 (1974). The legal transplant literature is wary of the notion that the law can be transplanted to further policymaking and legal reform efforts without regard to context. See Daniel Berkowitz et al., The Transplant Effect, 51 Am. J. Comp. L. 163, 168, 171 (2003) (observing that “the social, economic and institutional context often differs remarkably between origin and transplant country” and that “transplants either adapted the law to local conditions and/or had a population that was familiar with the transplanted law”). This Article does not advocate a simple cut-and-paste of a principle from one area of law to another. Indeed, Part III went through great length to develop and expand the framework sensitive to the uniqueness of highly-infectious diseases. As such, the expanded framework of CBDR is not a “classic transplant” and should not suffer from problems associated with them. For example, when transplants are not adapted to local conditions, a “transplant effect” happens, wherein less effective legal institutions persist when compared to the origin country. See Karen J. Alter, Laurence R. Helfer & Osvaldo Saldías, Transplanting the European Court of Justice: The Experience of the Andean Tribunal of Justice, 60 Am. J. Comp. L. 629, 634–35 (2012) (discussing the contention of Berkowitz et al., supra, that a mismatch between local institutions and the transplanted law arises absent adaptation to local needs).
