This landmark publication in the field of international law delivers expert assessment of new developments in the important work of the International Court of Justice (ICJ) from a team of renowned editors and commentators.The ICJ is the principal judicial organ of the United Nations and plays a central role in both the peaceful settlement of international disputes and the development of international law. This comprehensive Commentary on the Statute of the International Court of Justice, now in its third edition, analyses in detail not only the Statute of the Court itself but also the related provisions of the United Nations Charter as well as the relevant provisions of the Court's Rules of Procedure.
State immunity, the idea that a state, including its individual organs, officials and other emanations, may not be proceeded against in the courts of another state in certain instances, has long been and remains a source of international controversy. Although customary international law no longer recognizes the absolute immunity of states from foreign judicial process, the evolution of the contemporary notion of restrictive state immunity over the past fifty years has been an uncoordinated and contested process, leading to disputes between states. The adoption, in 2004, of the United Nations Convention on Jurisdictional Immunities of States and Their Property has significantly contributed to reaching consensus among states on this fundamental question of international law. This book provides article-by-article commentary on the text of the Convention, complemented by a small number of cross-cutting chapters highlighting general issues beyond the scope of any single provision, such as the theoretical underpinnings of state immunity, the distinction between immunity from suit and immunity from execution, the process leading to the adoption of the Convention, and the general understanding that the Convention does not extend to criminal matters. It presents a systematic analysis of the Convention, taking into account its drafting history, relevant state practice (including the considerable number of national statutes and judicial decisions on state immunity), and any international judicial or arbitral decisions on point.
This book traces the impact that the International Court of Justice (ICJ), the principal judicial organ of the United Nations, has had on various areas of international law. A number of prominent international experts examine whether, and to what extent, international law has been shaped by the Court's jurisprudence. The informal development of international law through the Court's judgments contrasts with the development of international law through more deliberate means, such as treaty-making. Assessing key areas of international law over which the ICJ has exercised its jurisdiction, such as international environmental law, international human rights, the law of the sea, and the law of immunities, this book comprehensively details the impact of international jurisprudence on contemporary international law. It makes required reading for anyone studying the ways in which international courts have in shaping the evolution of international law.
The concept of obligations erga omnes - obligations to the international community as a whole - has fascinated international lawyers for decades, yet its precise implications remain unclear. This book assesses how this concept affects the enforcement of international law. It shows that all States are entitled to invoke obligations erga omnes in proceedings before the International Court of Justice, and to take countermeasures in response to serious erga omnes breaches. In addition, it suggests ways of identifying obligations that qualify as erga omnes. In order to sustain these results, the book conducts a thorough examination of international practice and jurisprudence as well as the recent work of the UN International Law Commission in the field of State responsibility. By so doing, it demonstrates that the erga omnes concept is solidly grounded in modern international law, and clarifies one of the central aspects of the international regime of law enforcement. The dissertation, upon which this book is based, was awarded the 2005 Yorke Prize of the Faculty of Law of the University of Cambridge.
