This book provides an analysis of whether the International Criminal Court can be regarded as an International Criminal World Court, capable of exercising its jurisdiction upon every individual despite the fact that not every State is a Party to the Rome Statute. The analysis is based on a twin-pillar system, which consists of a judicial and an enforcement pillar. The judicial pillar is based on the most disputed articles of the Rome Statute; its goal is to determine the potential scope of the Court’s strength through the application of its jurisdiction regime. The enforcement pillar provides an analysis of the cooperation and judicial assistance mechanism pursuant to the Rome Statute’s provisions and its practical implementation through States’ practices. The results of the analysis, and the lack of an effective enforcement mechanism, demonstrate that the ICC cannot in fact be considered a criminal world court. In conclusion, possible solutions are presented in order to improve the enforcement pillar of the Court so that the tremendous strength of the ICC’s judicial pillar, and with it, the exercise of worldwide jurisdiction, can be effectively implemented.

This book concerns the relationship between the principles of complementarity and universal jurisdiction. Territorial States are normally affected most strongly by core international crimes committed during a conflict or an attack directed against its civilian population. Most victims reside in such States. Most damaged or plundered property is there. Public order and security are violated most severely in the territorial States. It is also on their territory that most of the evidence of the alleged crimes can be found. There are, in other words, obvious policy and practical reasons why States should accord priority to territoriality as a basis of jurisdiction. But is there also an obligation for States to defer exercise of universal jurisdiction of core international crimes to investigation and prosecution of the same crimes by the territorial State? What - if any - is the impact of the principle of complementarity in this respect? These are among the questions discussed in this anthology.

The book provides a holistic examination of the jurisdiction of the International Criminal Court (ICC). The main focus is placed on the three pillars which form the ICC’s foundation pursuant to the Rome Statute: the preconditions to the exercise of its jurisdiction (Article 12 Rome Statute) the substantive competence, i.e. the core crimes (Article 5-8bis Rome Statute, i.e. genocide, crimes against humanity, war crimes, crime of aggression) the principle of complementarity (Article 17§1 (a) Rome Statute) The latter governs the ICC's ‘ultimate jurisdiction’, since it is not merely sufficient for a crime to be within the Court's jurisdiction (according to the substantive, geographical, personal and temporal jurisdictional criteria), but the State Party must also be unwilling or unable genuinely to carry out the investigation or prosecution. Finally yet importantly, the main ‘negative preconditions’ for the Court’s jurisdiction, i.e. immunities (Article 27 Rome Statute) and exceptions via Security Council referrals are thoroughly examined.The book is an excellent resource for scholars as well as practitioners and notably contributes to the existing literature.

'State sovereignty' is often referred to as an obstacle to criminal justice for core international crimes by members of the international criminal justice movement. The exercise of State sovereignty is seen as a shield against effective implementation of such crimes. But it is sovereign States that create and become parties to international criminal law treaties and jurisdictions. They are the principal enforcers of criminal responsibility for international crimes, as reaffirmed by the complementarity principle on which the International Criminal Court (ICC) is based. Criminal justice for atrocities depends entirely on the ability of States to act. This volume revisits the relationship between State sovereignty and international criminal law along three main lines of inquiry. First, it considers the immunity of State officials from the exercise of foreign or international criminal jurisdiction. Secondly, with the closing down of the ad hoc international criminal tribunals, attention shifts to the exercise of national jurisdiction over core international crimes, making the scope of universal jurisdiction more relevant to perceptions of State sovereignty. Thirdly, could the amendments to the ICC Statute on the crime of aggression exacerbate tensions between the interests of State sovereignty and accountability? The book contains contributions by prominent international lawyers including Professor Christian Tomuschat, Judge Erkki Kourula, Judge LIU Daqun, Ambassador WANG Houli, Dr. ZHOU Lulu, Professor Claus Kre, Professor MA Chengyuan, Professor JIA Bingbing, Professor ZHU Lijiang and Mr. GUO Yang.

The chapters in this book are reworkings of presentations given during a conference held in 2018 at the German Embassy to the Netherlands in The Hague on the occasion of the 20th anniversary of the adoption of the Rome Statute. They provide an in-depth analysis of major points of contention the International Criminal Court (ICC) is currently facing, such as, inter alia, head of state immunities, withdrawal from the Rome Statute, the exercise of jurisdiction vis-à-vis third-party nationals, the activation of the Court’s jurisdiction regarding the crime of aggression, as well as the relationship of the Court with both the Security Council and the African Union, all of which are issues that have a continued relevance and carry a particular controversy. The collection provides insights from both practitioners, including judges of the ICC, and diplomats who participated in the negotiations leading to the adoption of the Rome Statute, as well as well-known academics from various parts of the world working in the field of international criminal law. The aim of the book is not only to inform and stimulate academic debate on the topic, but also to serve as an instrument for lawyers involved in the practice of international criminal law.
