International criminal justice: reflections on the past and the future

While Nuremberg constitutes a watershed in the evolution of international law with its establishment of the fundamental principle of individual criminal responsibility under international law it has not left much else by way of precedent for the subsequent international criminal tribunals. The adoption of UN Security Council Resolution 827 establishing the International Criminal Tribunal for the Former Yugoslavia, and Resolution 955 (1994) establishing the International Criminal Tribunal for Rwanda, set the groundwork for a new model of hybrid tribunals, with the establishment of the Special Court for Sierra Leone in 2002, the Extraordinary Chambers in the Courts of Cambodia in 2006, and the Special Tribunal for Lebanon in 2007. Perhaps one of the greatest legacies of these ad hoc and hybrid courts and tribunals has been paving the way for the establishment of a permanent international criminal court. However, they have also brought about the development of international criminal law through judicial interpretation, elaborating, inter alia, the elements of the crime of genocide as detailed in the 1948 Genocide Convention, the judicial recognition of the concept of joint criminal enterprise and the principle that national arrangements for amnesties in respect of international crimes are no bar to prosecution for such crimes at an international tribunal. In view of the completion strategies of the ad hoc Tribunals, as well as of the SCSL, this article delves into some of their legacies and outlines some of the difficulties and challenges they have faced, while identifying areas of best practice in order for the newly‐operational International Criminal Court to avoid repeating the mistakes of the past or even reinventing new wheels.
