The global effort to establish an effective system of international justice is at an important phase in its history. After close to 50 years of relative stagnation following the Nuremberg trials at the end of World War II, the field of international criminal law has been revitalised. The establishment of the International Criminal Court, the ad hoc tribunals for the former Yugoslavia and for Rwanda, “hybrid” or “internationalised” processes such as the Special Court in Sierra Leone, and national criminal justice systems exercising universal jurisdiction, have all lent substance and credibility to the assertion that the most grievous human rights crimes are subject to international scrutiny and legal action.
