The project considered how to maximize the impact of commissions of inquiry (COIs) that are established, usually by the Human Rights Council in Geneva but occasionally by the U.N. Security Council, to document the commission of international crimes in armed conflicts and repressive states. The project collated the various mandates, methodologies, outcomes, and impact of prior (and current) COIs with an eye toward developing best practices and recommending ways that future COIs can be designed to better contribute to processes of accountability for the crimes they document and the perpetrators they identify. In particular, the project generated proposals for better leveraging lists of perpetrators for accountability purposes and improving recruitment pathways for COIs.
