The Elgar Companion to the International Criminal Tribunal for Rwanda is a one-stop reference resource on this complex tribunal, established in the aftermath of the 1994 genocide in Rwanda, which closed its doors on 31 December 2015. This Companion provides an insightful account of the workings and legacy of the ICTR in the field of international criminal justice. Surveying and analyzing the contributions from different disciplinary angles, the Companion is comprised of four comprehensive parts. It begins with a detailed account of the establishment of the ICTR, covering the setting up of the tribunal, its mandate, structure and personnel. The second part explores substantive law and examines issues such as genocide, crimes against humanity, war crimes, sexual violence and modes of liability. The third part discusses procedural law and explores investigation, arrest, trial/appeal, evidence, rights of the accused, rights of victims and sentencing. It concludes with the fourth part, which considers the contribution of the ICTR to international criminal justice, as well as to the lives of Rwandans. An important contribution to the jurisprudence of international criminal courts, the Companion will appeal to academics, students and legal practitioners alike. It will be fascinating reading for anyone interested in international criminal law or the recent history of Rwanda. Contributors include: P. Akhavan, K. Ambos, S. Bock, C. Buisman, N.A.
