The International Criminal Tribunal for the former Yugoslavia (ICTY) does not merely represent a historical stage in the development of international criminal justice that can now be put aside and left to legal historians. It also has a lasting impact, due to the fact that its Rules of Procedure and Evidence are judge-made law, tested in the fire of court practice and frequently amended to take the latest developments into account. Additionally, with the arrest of Radovan Karad?ic, a new chapter has been opened for the Court. This volume provides an account of all the debates revolving around the proper role of international criminal justice, and it contributes to the developing academic discipline of "transitional justice." It also opens up a perspective to the International Criminal Court and asks what procedural legacy the ad hoc tribunals for Yugoslavia and Rwanda provide for the future of international criminal procedure.
