Book excerpt: The International Criminal Court is at a crossroads. In 1998, the Court was still a fiction. A decade later, it has become operational and faces its first challenges as a judicial institution. This volume examines this transition. It analyses the first jurisprudence and policies of the Court. It provides a systematic survey of the emerging law and practice in four main areas: the relationship of the Court to domestic jurisdictions, prosecutorial policy and practice, the treatment of the Courta (TM)s applicable law and the shaping of its procedure. It revisits major themes, such as jurisdiction, complementarity, cooperation, prosecutorial discretion, modes of liability, pre-trial, trial and appeals procedure and the treatment of victims and witnesses, as well as their criticisms. It also explores some of challenges and potential avenues for future reform.
