This course will begin with an overview of the notion of international crimes, the fundamental principles of international criminal law and the sources of that law. Subsequently, the course will focus on the substantive legal elements of war crimes, crimes against humanity and genocide, modes of liability for such international crimes and the growth in international criminal jurisdictions for holding individuals accountable for atrocities. As such, the course will consider the Nuremburg and Tokyo trials in the aftermath of World War II and the proliferation, post-Cold War, of international and “mixed” criminal courts and tribunals for prosecuting atrocities committed in the former Yugoslavia, Rwanda, Sierra Leone, Cambodia, and East Timor, among other places. In addition to covering the development of substantive international criminal law, the course will trace the development of an international criminal procedure. Specific issues to be explored include the efficacy of international criminal jurisdictions for fighting impunity for international crimes while upholding due process norms; the development of a consistent body of international criminal law jurisprudence; the relationship of international criminal jurisdictions to prosecution of international crimes by national courts; alternative mechanisms for effecting justice for international crimes including truth commissions and awarding reparations; State responsibility for international crimes; and the future of international criminal law.
