The Convention on the Privileges and Immunities of the United Nations and the Convention on the Privileges and Immunities of the Specialized Agencies entered into force more than 60 years ago. This Commentary offers for the first time a comprehensive discussion covering both Conventions in their entirety, providing an overview of academic writings and jurisprudence for a legal field of particular practical relevance and gives both the academic researcher as well as the practitioner a unique source to understand the complexity of legal issues that the UN, its Specialized Agencies, their officials, Member States' representatives, and experts face in today's world.

International organizations are increasingly operating across borders and engaging in legal transactions in virtually all jurisdictions. This makes, familiarity with the applicable law and practice imperative for both international organizations and those who engage in legal relations with them. Furthermore, the issue of whether, how, and to what extent domestic courts take into account decisions of foreign and international courts and tribunals in their own decision-making has become increasingly important in recent years. This book provides a comprehensive empirical study of this transnational judicial dialogue, focusing on the law and practice of domestic jurisdictions concerning the legal personality, privileges, and immunities of international organizations. It presents a selection of detailed country-by-country studies, examining the manner of judicial dialogue across domestic jurisdictions, and between national and international courts. The approach taken in this book intersects with three highly topical areas of international legal scholarship: the rapidly evolving law of international institutions; the burgeoning research into the role of domestic courts in the international legal system; and the recent rise of empirically-oriented legal scholarship. Utilizing OUP's International Law in Domestic Courts database, the book presents analysis of little-known cases which have real international significance, illustrating the impact and extent of transnational judicial dialogue in the international legal system. The book provides important perspectives on the evolution and status of the law of immunity of international organizations, and contributes to the understanding of relationships between national courts, and between national and international courts.

Immunity rules are part and parcel of the law of international organizations. It has long been accepted that international organizations and their staff need to enjoy immunity from the jurisdiction of national courts. However, it is the application of these rules in practice that increasingly causes controversy. Claims against international organizations are brought before national courts by those who allegedly suffer from their activities. These can be both natural and legal persons such as companies. National courts, in particular lower courts, have often been less willing to recognize the immunity of the organization concerned than the organization’s founding fathers. Likewise, public opinion and legal writings frequently criticize international organizations for invoking their immunity and for the lack of adequate means of redress for claimants. It is against this background that an international conference was organized at Leiden University in June 2013. A number of highly qualified academics and practitioners gave presentations and prepared written contributions that are collected in this book. This book is published to celebrate the 10th anniversary of the International Organizations Law Review, in which these contributions have also been published (Vol. 10, issue 2, 2014).

The past century has been a period of revolutionary change in many fields of human activity, in institutions and in thought. This period has seen the need of adjustment of state institutions and legal concepts to the needs of greater international cooperation. During the half century preceding the First World War, cooperation by governments outside the traditional diplomatic channels and procedures was largely limited to highly technical organizations, commonly referred to as public international unions, dealing with such matters as the im provement of postal communications and the control of contagious diseases. With the establishment of the League of Nations and the International Labor Organization at the end of the First World War, organized international cooperation assumed greater importance and the need was recognized of giving to the instruments of such cooper ation legal status and rights which would facilitate the effective performance of their functions. This proved to be a difficult adjustment for legal theory to make since the enjoyment of special privileges and immunities had been based in traditional international law on the fiction of state sovereignty. The new international organizations, while performing functions of the kind performed by national govern ments, were far from possessing the powers of such governments. The failure of the League of Nations to achieve its major purpose did not signify any permanent decline in the role of organized inter national cooperation.

The 1961 Vienna Convention on Diplomatic Relations has for over 50 years been central to diplomacy and applied to all forms of relations among sovereign States. Participation is almost universal. The rules giving special protection to ambassadors are the oldest established in international law and the Convention is respected almost everywhere. But understanding it as a living instrument requires knowledge of its background in customary international law, of the negotiating history which clarifies many of its terms and the subsequent practice of states and decisions of national courts which have resolved other ambiguities. Diplomatic Law provides this in-depth Commentary. The book is an essential guide to changing methods of modern diplomacy and shows how challenges to its regime of special protection for embassies and diplomats have been met and resolved. It is used by ministries of foreign affairs and cited by domestic courts world-wide. The book analyzes the reasons for the widespread observance of the Convention rules and why in the special case of communications - where there is flagrant violation of their special status - these reasons do not apply. It describes how abuse has been controlled and how the immunities in the Convention have survived onslaught by those claiming that they should give way to conflicting entitlements to access to justice and the desire to punish violators of human rights. It describes how the duty of diplomats not to interfere in the internal affairs of the host State is being narrowed in the face of the communal international responsibility to monitor and uphold human rights.

This book explores the relationship between the jurisdictional immunities of states and international organizations, in an attempt to bring clarity and predictability to the law of international immunities. Embracing a holistic approach, this book charts the history, purpose, scope, competing norms, and exceptions and waivers for the jurisdictional immunities related to states and then international organizations, respectively. Finally, it focuses on the relationship between the two areas analyzing in detail the differences and commonalities between the two.

Few topics of international law speak to the imagination as much as international immunities. Questions pertaining to immunity from jurisdiction or execution under international law surface on a frequent basis before national courts, including at the highest levels of the judicial branch and before international courts or tribunals. Nevertheless, international immunity law is and remains a challenging field for practitioners and scholars alike. Challenges stem in part from the uncertainty pertaining to the customary content of some immunity regimes said to be in a 'state of flux', the divergent – and at times directly conflicting - approaches to immunity in different national and international jurisdictions, or the increasing intolerance towards impunity that has accompanied the advance of international criminal law and human rights law. Composed of thirty-four expertly written contributions, the present volume uniquely provides a comprehensive tour d'horizon of international immunity law, traversing a wealth of national and international practice.

It gives me great pleasure to write a foreword to :\1r. Sen's excellent book, and for two reasons in particular. In the first place, in producing it, Mr. Sen has done something vvhich I have long felt needed to be done, and which I at one time had am bitions to do myself. \Vhen, over thirty years ago, and after some years of practice at the Bar, I first entered the legal side of the British Foreign Service, I had not been working for long in the Foreign Office before I conceived the idea of writing - or at any rate compiling - a book to which (in my own mind) I gave the title of "A ~fanual of Foreign Office Law. " This work, had I ever produced it in the form in which I visualised it, could probably not have been published con sistently with the requirements of official discretion. But this did not worry me as I was only contemplating something for private circulation within the Service and in Government circles. :Mr. Sen's aim has been broader and more public-spirited than mine was; but its basis is essentially the same.

This book proposes that fundamental concepts of institutional law need to be rethought and revised. Contrary to conventional wisdom, international organizations do not need to have members, and the members do not need to be states and international organizations. Private sector entities may, for instance, also be full members. Furthermore, international organizations do not need to possess international legal personality, nor is their autonomy a corollary of their personality. Moreover, the notion of “subject of international law” also needs to be reconsidered and the very concepts and definitions of “intergovernmental organization” and “international organization” need to change and be defined in a wider manner. In this publication the legal implications of membership are analyzed and a new analytical framework for international organizations is proposed. The argument is propounded that the power of creation of new organizations has passed over to international organizations and other entities while an outlook on future development is also presented. Dr. Gerd Droesse is a recognized specialist in institutional law, international administrative law, complex institutional and financial policy matters and corporate governance issues, with over 30 years of experience in working for international organizations in senior and management positions. He was the Legal Counsel/Acting General Counsel of the Green Climate Fund and assisted the World Green Economy Organization as General Counsel in its transition to a new type of intergovernmental organization.
