Effective enforcement remains one of the greatest challenges for international bodies seeking to advance global human rights norms. Despite the rapid proliferation of intergovernmental organizations, regional systems, international treaties, soft-law declarations, and non-government organizations since the Second World War, human rights violations persist. Arguably, however, despite the prominent role played by institutions such as the United Nations and the International Court of Justice, the most effective human rights mechanisms do not operate at the global level. Rather, the greatest potential for effective enforcement lies within regional human rights systems and the tribunals they establish. By translating global human rights norms into local cultural terms, incentivizing domestic policy changes through the ratification of treaties, and encouraging compliance with institutionally transformative equitable remedies by facilitating pro-compliance intergovernmental coalitions, regional systems have the potential to become the most effective enforcement mechanism of international human rights norms. 

Regional human rights systems play a key role in bridging the gap between universalism and cultural pluralism by translating global human rights norms into local cultural terms, thereby increasing the likelihood of state compliance. Although global human rights institutions receive broad support, considerably more debate revolves around the value of regional systems. In particular, tension exists between those who believe human rights are universal and, as such, should be enforced by international bodies, and those who endorse regional approaches to enforcement that respect culturally pluralistic human rights practices. Such a false dichotomy not only overlooks the value of human rights treaties that reflect regional characteristics, but also ignores the fact that universalist and pluralist approaches are not antithetical but synergistic. Even a cursory examination of their major instruments reveals that regional systems acknowledge unique local characteristics within the broader context of international human rights norms. The preamble of the European Convention on Human Rights (ECHR) explicitly acknowledges that “the [Universal Declaration of Human Rights (UDHR)] aims are securing the universal and effective recognition and observance of the Rights declared therein” (italics added). The American Convention on Human Rights similarly acknowledges, “in accordance with the [UDHR], the ideal of free men enjoying freedom from fear and want”—a recognition of universal human rights that appears in numerous other Inter-American declarations. The African Charter on Human and People’s Rights not only gives “due regard to the Charter of the United Nations and the [UDHR],” but further reaffirms “adherence to the principles of human and peoples’ rights and freedoms contained in the declarations, conventions and other instruments adopted by… the United Nations.” Global human rights norms are deeply embedded into the text of regional instruments, and international precedents and soft law are frequently cited to lend legitimacy to the jurisprudence of regional courts. As Flávia Saldanha Kroetz notes in her critical analysis, regional human rights systems “[reflect] an attempt to strengthen the protection of basic rights while underlining regional characteristics and common values shared by certain States, as opposed to an overarching, central scheme accused of overlooking the features of each region.” Within the realm of human rights, universalism underpins pluralism, and pluralism bolsters universalism. In practice, if not in theory, the two are inextricable. 

Although the basic human rights principles within global and regional instruments largely align, regional instruments add nuance to broad normative standards that reflects local traditions and values. As the Twenty-Eighth Report of the Commission to Study the Organization of Peace noted, “[T]he regional instrument might go further [than the global instrument], add further rights, refine some rights, and take into account special differences in the region and between one region and another.” This is valuable not simply because it acknowledges cultural diversity, but, more importantly, because it increases the likelihood of domestic implementation and compliance. According to a recent study, both qualitative and quantitative data analyses reveal a correlation between social norms and implementation, noting that “populations resist the implementation of human rights when their provisions do not match social norms, and are supportive of implementation when provisions do match norms.” Resistance to implementation may be particularly pronounced in post-colonial regions where global human rights mechanisms can be perceived as a form of “pro-Western” cultural imperialism—and thus as an unwelcome interference. Decentralization to regional systems, however, empowers geographically and often culturally related state groups to translate global human rights norms into instruments that reflect their unique regional interests, approaches, and social milieux. The singular inclusion of “peoples’ rights” in the African Charter, borne out of Africa’s exploitative colonial history, provides a compelling example. Translating global human rights norms into local cultural language is fundamentally important, given the inability of either global or regional institutions to enforce compliance from the top down. As Saldanha Kroetz points out, “The applicability of human rights treaties that challenge local practices is often undermined by national or local authorities on the basis of the significance of traditions and beliefs for social cohesion and maintenance of the status quo.” Instead, mechanisms must be structured to facilitate compliance from the bottom up, beginning with domestic institutions and local actors. 

Within regional systems, human rights treaties are the cornerstone for incentivizing the compliance of domestic institutions. In their study analyzing the effects of ratification of the Convention on the Rights of the Child (CRC) in Ecuador, Chile, and Argentina, Jean Grugel and Enrique Peruzzotti observed that mere treaty ratification “can lead to pressure from organizations within global civil society to improve human rights records.” By opening up debate about treaty compliance and strengthening the legitimacy of civil groups, treaty ratification can open the door to broadened human rights awareness, the development of new legislation, and the establishment of a new language of rights. As Grugel and Peruzzotti go on to note, “compliance can be pushed by state and civil society actors… or led by either of them… [T]he agenda of compliance is broadest when a strong rights-based civil society network encounters state actors willing to embrace rights-based change.” External pressures further incentivize states to conform to treaty obligations. While diplomatic implications provide some deterrence to systematic treaty violations, regional human rights tribunals provide the strongest check on state behaviour. “Through their jurisprudence, fact-finding missions, consultations with states, and agenda-setting powers, human rights tribunals have the potential to exercise significant influence over member states’ human rights practices.” Measurable efficacy varies between tribunals, which experience significant disparities in compliance rates. According to a study by Courtney Hillebrecht, “ECtHR has a 49 percent compliance rate, which is remarkably high for an international tribunal. Meanwhile, the IACtHR has a 34 percent compliance rate.” Although she attributes this to the longer history, strongly developed enforcement mechanisms, and more interactive approach of the ECtHR, high compliance rates may also be attributed to the nature of its judgements. Where the ECtHR has broadly adopted the principle of a margin of appreciation when ordering remedies, the IACtHR “is the only international human rights boy with binding powers that has consistently ordered equitable remedies in conjunction with compensation.” This approach acts as a double-edged sword. On the one hand, such ubiquitous equitable remedies, if undertaken, would have far greater efficacy in protecting human rights and minimizing future impunity than mere compensation—which may well be regarded as a “slap on the wrist.” They can further, as Hillebrecht notes, “[change] the domestic human rights agenda and [provide] political cover for rights reform.” As such, equitable remedy orders by regional tribunals can be one of the most effective enforcement mechanisms to facilitate long-term human rights changes. On the other hand, if domestic actors lack the necessary political will and influence to implement such remedies, costly compliance measures will only be ignored. 

Such difficulties in ensuring compliance place tribunals in a challenging place. Do they heighten the likelihood of compliance by granting states a “margin of appreciation” to implement their own remedies (like the ECtHR), or do they order more specific equitable remedies which, if complied with, will foster the institutional change necessary for long-term human rights enforcement (like the IACtHR)? By strategically adjusting their engagements with responsible states, regional tribunals may be particularly poised to overcome this problem, as they are uniquely capable of cultivating domestic actors as “partners in compliance” and encouraging such actors to build “pro-compliance coalitions”: “the process of compliance depends on coalitions of domestic actors—executives, judiciaries, legislatures, and civil society—that are able and willing to push through human rights reform.” Robust domestic coalitions are central to the ECtHR’s high compliance rates, and their absence, coupled with its role as a remedial regime, may partially explain the high levels of impunity experienced by the IACtHR. An ideal approach arguably lies somewhere between the two, pairing the ECtHR’s successful interactive engagement with domestic actors, which considerably heightens the likelihood of state compliance, with the IACtHR’s practice of ordering equitable remedies, which would serve to strengthen the human rights practices of domestic institutions over the long-term. 

The ideal human rights enforcement mechanism shares qualities with African, American, and European human rights systems. Regional systems provide beneficial avenues to engage with domestic actors on their own terms (quite literally) by translating human rights norms into culturally compelling language. To increase the likelihood of local support and domestic implementation, systems must strike a delicate balance between engaging and challenging member states: “Rights need to be presented in local cultural terms in order to be persuasive, but they must challenge existing relations of power in order to be effective” (Sally Engle Merry, 16). While the ratification of regional treaties is likely to facilitate important internal pressures on states to discuss, legislate, and enforce new human rights norms, effective human rights tribunals are an important external enforcement mechanism. Existing human rights tribunals offer important insights into how courts can best engage with domestic actors to heighten compliance rates through strategic interactive engagement and judgements that move beyond recompense and towards valuable equitable remedies. Strong regional systems which incentivizing robust domestic institutions and bolster pro-compliance intergovernmental coalitions are perhaps the most fundamental and most easily overlooked lynchpin for successful human rights enforcement.
