The International Criminal Court ushers in a new era in the protection of human rights. The ICC will prosecute genocide, crimes against humanity and war crimes when national justice systems are either unwilling or unable to do so themselves. Schabas reviews the history of international criminal prosecution, the drafting of the Rome Statute of the International Criminal Court and the principles of its operation, including the scope of its jurisdiction and the procedural regime. This revised edition considers the court's start-up preparations, including election of judges and prosecutor. It also addresses the difficulties created by US opposition, and analyses the various measures taken by Washington to obstruct the Court. Three of the Court's fundamental documents - the 1998 Rome Statute, the Rules of Procedure and Evidence, and the Elements of Crimes - are reproduced in the Appendix. Indispensable for students and practitioners.
