This book theorizes the ways in which states that are presumed to be weaker in the international system use the International Criminal Court (ICC) to advance their security and political interests. Ultimately, it contends that African states have managed to instrumentally and strategically use the international justice system to their advantage, a theoretical framework that challenges the “justice cascade” argument. The empirical work of this study focuses on four major themes around the intersection of power, states' interests, and the global governance of atrocity crimes: firstly, the strategic use of self-referrals to the ICC; secondly, complementarity between national and the international justice system; thirdly, the limits of state cooperation with international courts; and finally the use of international courts in domestic political conflicts. This book is valuable to students, scholars, and researchers who are interested in international relations, international criminal justice, peace and conflict studies, human rights, and African politics.
