The establishment of international criminal jurisdictions such as the International Criminal Court ('ICC') presents new challenges for legal practitioners as well as scholars in their legal research. High-quality legal commentaries can be of great assistance for both practitioners and scholars. The Commentary on the Law of the International Criminal Court ('CLICC') has been designed with inspiration from commentaries on domestic law as well as international law. It now covers both the ICC Statute and Rules of Procedure and Evidence. Its basic idea is to address legal questions and issues in a clear and unconvoluted manner. It not only discusses ordinary and recurrent questions of interpretation and application of international criminal law. When legal issues are more complicated, CLICC informs on relevant preparatory works, case law, expert views and scholarship which may be consulted for further research. This volume concerns the ICC Rules of Procedure and Evidence. It contains contributions by 20 experts from diverse backgrounds: Mohamed Abdou, Wenke Brückner, Enrique Carnero Rojo, Karel De Meester, Julia Dornbusch, Mayeul Hiéramente, Mark Klamberg, Iryna Marchuk, Anna Oehmichen, Juan P. Pérez-León-Acevedo, Dejana Radisavljevic, Sophie Rigney, Geoff Roberts, Michael Stiel, Carl-Friedrich Stuckenberg, Melinda Taylor, Jenia Iontcheva Turner, Sergey Vasiliev, Aloka Wanigasuriya and Zhang Yueyao.
