The complementarity of the International Criminal Court (ICC) is one of the fundamental principles of the Rome Statute for the International Criminal Court. The principle of complementarity is the parameter which defines the relationship between States and the ICC. It provides that cases are admissible before the ICC if a State remains wholly inactive or is 'unwilling' or 'unable' to investigate and prosecute genuine cases of genocide, crimes against humanity and war crimes. The Amsterdam Center for International Law and the Department of Legal Philosophy at the Law Faculty of the Free University of Amsterdam held an international expert roundtable on the 'Complementarity Principle of the Rome Statute of the International Criminal Court' on 25 and 26 June 2004. This book contains contributions on complementarity, which were presented and discussed during that meeting. They analyse the principle from theoretical, practical and conceptual perspectives.

This books provides an in-depth analysis of the international legal aspects of the use of depleted uranium (DU) ammunition and armour. The military use of DU has been surrounded by considerable controversy, mainly as regards the health and environmental risks that such use entails. The debate about DU has thus far been highly polarised, with one end of the spectrum rejecting any risk whatsoever and the other end suggesting that the use of DU leads to severe health and environmental consequences, including Gulf-War syndrome, whenever it is used. Rather than settling these controversies, the book takes as a starting point a precautionary approach in light of the considerable remaining scientific uncertainties. It examines various principles and rules of international law, which would be at play if the health and environmental concerns regarding the use of DU were to materialise.

Jus ad bellum and jus in bello are established concepts in contemporary international law. This book is the first work to treat the origins, contents and contemporary challenges of jus post bellum. It offers new analysis and fresh thinking on one of the greatest challenges of warfare and armed force: the management and restoration of peace after conflict. Fundamental issues, such as the extraterritorial application of human rights obligations, the accountability of occupying powers and international organizations and approaches towards justice and reconciliation, are at the heart of contemporary debate. New concepts, such as the notion of responsibility to protect are gradually emerging. This book addresses these issues from a novel perspective. It identifies legal gaps and policy challenges and inquires to what extent they may be addressed under a common normative umbrella: Jus Post Bellum. The individual contributions offer guidance on shortcomings, directions and possible avenues of reform. In this way, the authors - from various disciplines, such as philosophy, legal history, political science and international law - contribute to the emerging scholarship in this field.

In response to the weaknesses of international tribunals and domestic courts in the prosecution of crimes such as genocide, crimes against humanity and war crimes, a new generation of "internationalized" criminal courts has been established. This book addresses three active and one putative jurisdiction of this kind in East Timor, Kosovo, Sierra Leone, and Cambodia.
