The Puzzle of Atrocity Criminalization

Abstract

Why do governments take atrocity offenses, like genocide, war crimes, and crimes against humanity, from international law and legislate them into domestic criminal law, empowering national courts to prosecute their own, and sometimes other states’, government and military officials? The question is important, because the international community has constructed an international legal regime to prosecute the most serious human rights violations, but that regime is designed to rely primarily on domestic criminal courts to try offenders. To fulfill this role, domestic courts often require specific legislation that defines and criminalizes these offenses in national law. Yet, the adoption of national atrocity laws is puzzling, since in a number of ways, these laws appear to threaten states’ interests. This introductory chapter highlights the puzzle of atrocity criminalization and discusses its importance for the functioning of the international atrocity regime. It then situates this study in existing literatures and highlights the book’s contributions to research on atrocity justice, human rights, and international law. Next, it summarizes the book’s main arguments and details the study’s multi-method research design, which combines quantitative analyses of new, original datasets with in-depth qualitative case studies of Guatemala, Colombia, Poland, and the Maldives.
