Ed. Roberto Bellelli. This volume presents an overview of the principle features of the legacy of International Tribunals and an assessment of their impact on the International Criminal Court and on the review of the Rome Statute. It illustrates the foundation of a system of International Criminal Law and Justice, through the case-law and practices of the UN ad hoc tribunals and other internationally assisted tribunals and courts, mainly through contributions of the principals and other officials involved in investigation, prosecution and trials. The challenges of these experiences are underlined with a lesson-learned approach, which provides advice for possible future developments in international criminal procedure and law, with particular reference to their impact on the ICC and on national jurisdictions. The 2010 first Review Conference of the Rome Statute of the ICC is approached as a step of a review process and from the perspective of the developments in the field, since the adoption of the Statute in 1998. Issues addressed are: methodology and scope, procedural and substantive criminal law, and political matters. Leading scholars and States' officials provide their assessment thereof.
