In The Roles and Functions of Atrocity-Related United Nations Commissions of Inquiry in the International Legal Order, Catherine Harwood explores the turn to international law in atrocity-related United Nations commissions of inquiry and their navigation of considerations of principle (the legal) and pragmatism (the political), to discern their identity in the international legal order. The book traces the inquiry process from establishment and interpretation of the mandate to legal analysis, production of findings and recommendations. The research finds that the turn to international law fundamentally shapes the roles and functions of UN atrocity inquiries. Inquiries continuously navigate between realms of law and politics, with the equilibrium shifting in different moments and contexts.
