Introduction
Traditionally, international law has been understood as a system governing the relations between sovereign states. Consequently, international human rights law (IHRL) has primarily focused on the vertical relationship between the state and the individual, where states are the principal duty-bearers responsible for respecting, protecting, and fulfilling human rights. However, the landscape of international relations has changed significantly, with a variety of non-state actors (NSAs) now wielding considerable power and influence, often rivalling or even exceeding that of states. This essay will discuss the evolving role of these actors in IHRL. It will argue that while states remain the primary legal subjects, the activities of NSAs such as transnational corporations, armed opposition groups, and non-governmental organisations have created a pressing need for the law to adapt. This essay will demonstrate that while NSAs are increasingly recognised as having a significant impact on human rights, the legal frameworks for defining their obligations and ensuring accountability remain underdeveloped and contested.
The State-Centric Foundation of Human Rights Law
The modern international human rights system, established after the Second World War, is built upon a foundation of state consent and sovereignty. Major human rights treaties, such as the International Covenant on Civil and Political Rights (ICCPR) and the International Covenant on Economic, Social and Cultural Rights (ICESCR), are addressed to "States Parties." Article 2(1) of the ICCPR, for example, obliges each State Party "to respect and to ensure to all individuals within its territory and subject to its jurisdiction the rights recognized in the present Covenant". This language clearly establishes the state as the main holder of obligations. The state's duty is twofold: a negative obligation to refrain from violating rights (to respect), and a positive obligation to prevent and punish violations by private actors and to take steps to realise rights (to protect and fulfil). Under this traditional model, an NSA like a corporation that pollutes a community's water supply does not directly violate an international right to water; rather, the state violates its duty by failing to regulate the corporation and provide a remedy (Alston and Goodman, 2013). This state-centric model provides a clear, albeit limited, chain of accountability.
Transnational Corporations and the Accountability Gap
Among the most powerful NSAs are transnational corporations (TNCs), whose economic influence and global reach can have profound impacts on human rights. Issues such as labour exploitation in supply chains, environmental degradation, and complicity in abuses committed by state security forces have brought the conduct of TNCs into sharp focus. The central legal problem is that, as non-signatories to treaties, TNCs do not have direct, binding obligations under most international human rights instruments. This creates a significant "governance gap" where powerful actors can operate in jurisdictions with weak regulatory frameworks, leading to human rights abuses with impunity (Ruggie, 2008).
In response, the international community has moved towards developing non-binding standards of conduct. The most significant development is the United Nations "Protect, Respect and Remedy" Framework, proposed by Special Representative John Ruggie and endorsed by the UN Human Rights Council in 2008, and its accompanying Guiding Principles on Business and Human Rights (UNGPs) (OHCHR, 2011). The UNGPs are based on three pillars:
- The State Duty to Protect: This reaffirms the traditional state obligation to protect against human rights abuses by third parties, including businesses.
- The Corporate Responsibility to Respect: This introduces a standard of conduct for all businesses to respect human rights, meaning they should avoid infringing on the rights of others and address adverse impacts with which they are involved. This is achieved through human rights due diligence.
- Access to Remedy: This pillar highlights the need for effective remedies for victims, through both state-based judicial and non-judicial mechanisms and company-level grievance mechanisms.
While the UNGPs have been hugely influential, they are "soft law," meaning they are not legally binding. Their effectiveness relies on implementation by states into domestic law and voluntary adoption by corporations. Attempts to hold corporations accountable through domestic courts using international law, such as via the Alien Tort Statute in the United States, have had limited success, with courts often reluctant to apply international norms directly to corporate actors (see, for example, Kiobel v Royal Dutch Petroleum Co, 569 U.S. 108 (2013)). This leaves a persistent challenge in ensuring that corporate respect for human rights is a matter of legal obligation rather than corporate social responsibility.
Armed Opposition Groups: From IHL to IHRL
Another category of NSA that poses a major challenge to human rights is armed opposition groups or insurgents. In many contemporary conflicts, these groups control territory and populations, effectively performing state-like functions. They are also frequently responsible for some of the most severe human rights violations, including summary executions, torture, and sexual violence.
Traditionally, the conduct of such groups during conflict is regulated by International Humanitarian Law (IHL), also known as the law of armed conflict. Common Article 3 to the 1949 Geneva Conventions, for instance, sets out minimum standards of humane treatment applicable in non-international armed conflicts and explicitly binds "each Party to the conflict," which includes non-state armed groups. However, IHL's primary focus is on regulating the means and methods of warfare, not the full spectrum of human rights.
There is a growing, though contested, academic and policy movement arguing that where an armed group exercises stable control over territory and a population, it should also be bound by certain IHRL obligations (Clapham, 2006). The rationale is that if such a group acts like a state, it should bear similar responsibilities to protect the rights of those under its control, such as the right to a fair trial or education. However, a major objection is that this could be seen as legitimising such groups, and it remains difficult to determine the precise legal basis and scope of such obligations. For now, the primary route for accountability for individuals within these groups is through international criminal law, with tribunals like the International Criminal Court (ICC) having jurisdiction to prosecute war crimes, crimes against humanity, and genocide, regardless of whether the perpetrator is a state or non-state actor.
Non-Governmental Organisations as Human Rights Advocates
In contrast to actors who may violate rights, non-governmental organisations (NGOs) play a crucial and largely positive role in the IHRL system. International NGOs like Amnesty International and Human Rights Watch, along with countless national and local organisations, are fundamental to the promotion and protection of human rights. Their role is multifaceted.
First, they act as monitors and information-gatherers. By investigating and documenting abuses, they provide essential information to UN bodies, regional courts, and the global public, engaging in "naming and shaming" to pressure states into compliance. Second, they are powerful advocates. NGOs were instrumental in campaigning for the adoption of key treaties, such as the Convention against Torture and the Rome Statute of the ICC. Third, many NGOs provide direct assistance to victims, including legal aid to bring cases before domestic or international tribunals. For example, organisations frequently submit amicus curiae briefs to bodies like the European Court of Human Rights, providing valuable legal expertise. Finally, many have a formal role within the UN system, with bodies like the Economic and Social Council (ECOSOC) granting consultative status to NGOs, allowing them to participate in meetings and contribute to debates (De Feyter, 2005). In these ways, NGOs act as a vital part of the enforcement machinery of IHRL, helping to bridge the gap between legal norms and state practice.
Conclusion
The role of non-state actors in international human rights law is complex and continually evolving. The traditional state-centric model, while still the legal bedrock of the system, is no longer sufficient to address the reality of global power. Powerful NSAs, particularly transnational corporations and armed groups, are capable of committing widespread human rights abuses, yet often fall into an accountability gap. The international community has begun to respond through soft-law initiatives like the UNGPs and the application of IHL and international criminal law to armed groups, but these measures are partial and lack the force of direct, binding treaty obligations. At the same time, other NSAs, primarily NGOs, have become indispensable partners in the work of monitoring state behaviour and advocating for stronger protections. Ultimately, while states remain the primary addressees of international human rights law, the practical reality is that NSAs are now central figures in the field. The great challenge for the future development of the law is to create more robust and effective legal frameworks to regulate the conduct of all powerful actors, not just states, to ensure human rights are universally protected.
