- Abstract:
- This white paper addresses three questions that arise when a non-state actor that is receiving assistance from a state actor in a non-international armed conflict engages in detention activities: (1) Under international law, when does a non-state actor have the authority to detain individuals captured in the course of a non-international armed conflict? (2) When does a state providing assistance to a non-state actor become responsible under international law for the non- state actor’s actions? (3) Assuming such responsibility exists, what actions must the state take if it believes the non-state actor may engage in human rights abuses or violations of the law of armed conflict? In response to the first question, neither the Geneva Conventions nor customary international humanitarian law provides a legal basis for non-state actors to detain captured individuals in non-international armed conflicts. However, international humanitarian law also does not expressly prohibit non-state actors from detaining individuals. Instead, it regulates the conditions of detention. If non-state actors comply with Common Article 3 of the Geneva Conventions and relevant provisions of the Second Additional Protocol, detention by armed groups in non-international armed conflict does not violate an explicit provision of international humanitarian law. As long as detention is not arbitrary, internment by non-state actors is also unlikely to constitute the war crime of unlawful confinement. In response to the second question, under agency-based theories of the state responsibility doctrine, actions of non-state actors may be directly attributed to the state if (1) the state exercises either strict or overall control over the non-state actor such that the group operates as a de jure or de facto state organ or (2) the state exercises effective control over a specific operation undertaken by the non-state actor. Additionally, to the extent Common Article 1 requires states to ensure that all parties to an armed conflict respect the Geneva Conventions, it may create an alternative and additional source of state liability for the actions of non-state actors. Finally, in response to the third question, this white paper recommends a series of ex ante and ex post measures states can adopt when engaging with a non-state actor. These include, vetting, training, acquiring written agreements, providing punishment frameworks, and ceasing support when actors commit violations of IHL. Since existing jurisprudence does not contemplate mitigation of state responsibility for the conduct of non-state actors, it is difficult to assess to what extent any of the proposed measures would limit the state’s liability. Nevertheless, states adopting these recommendations will both make violations less likely and be more likely to discharge their duties under international humanitarian and human rights law. By taking ex ante measures designed to prevent violations and creating ex post incentives for non-state partners to comply with IHL norms, states reduce the risk armed groups will engage in detention practices that violate international law.
