This new book by Professor Cassese acts as an excellent general introduction to international criminal law for students and practitioners alike and as a stimulus to other scholars or practitioners to delve deeper into its principal notions. It provides a clear and concise account of the principles governing international crimes and an outline of international criminal trials. Adopting a combination of the classic common law and more theoretical approaches to the subject, it expounds the fundamentals of both substantive and procedural international criminal law, providing a theoretical framework to all the rules, principles, concepts, and legal constructs key to the subject. It also offers extensive treatment of the most significant traditional and novel cases in English, as well as unique English translations of a selection of relevant judgments in Dutch, French, German, Italian, and Spanish, demonstrating the historical and human dimensions of such cases, and providing effective illustration of the practical problems encountered by criminal courts. Antonio Cassese is the Editor of the Journal of International Criminal Justice. To read sample articles from the journal visit: www.jicj. oupjournals.org
