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. Six years after the publication of the second edition, the third edition of the Commentary embraces current events before the International Court of Justice as well as before other courts and tribunals relevant for the interpretation and application of its Statute.The Commentary provides a comprehensive overview and analysis of all legal questions and issues the Court has had to address in the past, and looks forward to those it will have to address in the future. It illuminates the central issues of procedure and substance that the Court and counsel appearing before it face in their day-to-day work.In addition to commentary covering all of the articles of the Statute of the ICJ, plus the relevant articles of the Charter of the United Nations, the book includes two scene-setting chapters: Historical Introduction and General Principles of Procedural Law, as well as important and instructive chapters on Counter-Claims, Discontinuation and Withdrawal, and Evidentiary Issues.

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. Continuing the work started by Sir Hersch Lauterpacht's influential book The Development of International Law by the Permanent Court of International Justice, this book provides key new insights into the role of the Court in wider international law. It makes required reading for anyone studying the ways in which international courts have in shaped the evolution of international law.

International economic law is one of the crucial branches of international law, and of major importance both practically and conceptually. This document collection brings together all of the most important treaties, regulations, and other documents in this area. It presents the key documents of contemporary international economic law in one single volume, so to provide students as well as practitioners with an accessible reference guide. The book will feature a brief introduction, providing readers with a 'roadmap' through what is perceived by many as the maze of international economic law.The collection brings together documents relating to the three main pillars of international economic law, namely world trade law, international monetary law, and international investment law. These are preceded by texts of a more general character, notably issued by the United Nations and clarifying the parameters of international economic relations. This broad focus enables readers to view international economic law in its breadth and to avoid the pitfalls of a 'compartmentalised' approach, which exclusively focuses on, for example, WTO law or investment law without appreciating their interrelation. By bringing together key texts of all three branches, the book should be invaluable to students taking general courses of international economic law as well as more specialised courses such as WTO law or investment 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 Research Handbook on the Law of Treaties provides an authoritative treatment of fundamental issues in international treaty law. Identifying key challenges facing the modern law of treaties, the Handbook addresses the current regime and comments on potential directions of the law.Rather than an article-by-article commentary on provisions applicable to treaties, the Handbook offers an innovative study of their spatial, personal and temporal dimensions and of the tensions that arise due to the need for both flexibility and certainty in treaty relations. It analyses the interaction between treaty regimes and potential ruptures, as well as the expansion of treaty law to international organisations, corporations and individuals. Each chapter includes an 'agenda for research', highlighting areas where future work could yield significant results.This pioneering Handbook will prove an invaluable resource for researchers and advanced students, as well as providing unique insights for practitioners of international law.Contributors: E.

In this book, self-defence against non-state actors is examined by three scholars whose geographical, professional, theoretical, and methodological backgrounds and outlooks differ greatly. Their trialogue is framed by an introduction and a conclusion by the series editors. The novel scholarly format accommodates the pluralism and value changes of the current era, a shifting world order and the rise in nationalism and populism. It brings to light the cultural, professional and political pluralism which characterises international legal scholarship and exploits this pluralism as a heuristic device. This multiperspectivism exposes how political factors and intellectual styles influence the scholarly approaches and legal answers and the trialogical structure encourages its participants to decentre their perspectives. By explicitly focussing on the authors' divergence and disagreement, a richer understanding of self-defence against non-state actors is achieved, and the legal challenges and possible ways ahead identified.

The second edition of this book provides students, scholars, and practitioners of international law with easy access to the key primary sources in international dispute settlement, allowing users to focus on engaging with the primary material, rather than trying to source it.The text has been expanded and updated to reflect developments in this rapidly changing field. It includes dispute settlement provisions of treaties adopted since the first edition (such as the Paris Agreement on Climate Change and the WTO Multi-Party Interim Appeal Arbitration Agreement) and takes stock of changes affecting proceedings before investment tribunals, the European Court of Human Rights, and the International Court of Justice. A new subject index improves navigation.This title is included in Bloomsbury Professional's International Arbitration online service.

This book provides the first analysis of the EU-UK Trade and Cooperation Agreement (TCA), which was established to ensure mutual respect and preferential trading relationships between the UK (as a non-Member State) and the European Union.In addition to offering a clear and comprehensible overview of the legal and institutional framework under international, European and UK law, it gives detailed guidance to trade in specific sectors. These include: trade in goods, services and capital; digital trade; energy; fisheries; and investment. It also examines broader themes such as sustainability; health security; cybersecurity; and dispute resolution. This is an invaluable tool for all commercial lawyers working on international trade in the EU and in the United Kingdom.

International investment law has often been seen as an obstacle to sustainable development. While the connections between investment and development are plain, for a long time there has been relatively little scholarship exploring them. Combining critical reflection and detailed analysis, this book addresses the relationship between contemporary investment law and development.The book is organized around two competing visions of investment and development - as working either harmoniously or in conflict with one another. The expert contributors reflect on both of these views and analyse the social dimensions of development and its impact on investment law. Coverage includes in-depth discussion on such issues as human rights, poverty reduction, labor standards, and indigenous peoples.Students and scholars of international investment law will benefit from the informed analysis of the links between investment and development. This book will also be of use to practitioners and experts of development law who are looking for an up-to-date perspective of the field.Contributors: W. Ben Hamida, C. Binder, J. Bonnitcha, M.-C.

The global crises of the early 21st century have tested the international financial architecture. In seeking to ensure stability, governments have regulated financial and capital markets. This in turn has implicated international investment law, which investors have invoked as a shield against debt restructuring, bail-ins or bail-outs. This book explores whether investment law should protect against such regulatory measures, including where these have the support of multilateral institutions. It considers where the line should be drawn between legitimate regulation and undue interference with investor rights and, equally importantly, who draws it. Across the diverse chapters herein, expert international scholars assess the key challenges facing decision makers, analyze arbitral and treaty practice and evaluate ways towards a balanced system of investment protection in the financial sector. In doing so, they offer a detailed analysis of the interaction between investment protection and financial regulation in fields such as sovereign debt restructuring and bank rescue measures. Combining high-level analysis with a detailed assessment of controversial legal issues, this book will provide guidance for both academics and legal practitioners working in international economic law, international arbitration, investment law, international banking and financial law.Contributors include: A.

Historiographical approaches to international investment law scholarship are becoming ever more important. This insightful book combines perspectives from a range of expert international law scholars who explore ways in which using a broad variety of historical methods and historical research can lead to a better understanding of international investment law.International Investment Law and History critically analyses the use of historical argument in international investment law. It examines the vital roles that historical arguments play in interpreting investment treaties, resolving investor-state disputes, and justifying or criticising the current system of investment protection.This book is the first in-depth study on the methodological challenges and benefits of historical analysis in international investment law. As such, it is a vital tool for scholars and practitioners in the field who wish to understand ways in which to use historical research and analysis to improve and redefine international investment law.Contributors include: M. Boase, H. Bray, Y. Chernykh, J. Ho, R. Hofmann, J. Kammerhofer, A. Kulick, K. Miles, M. Pinchis-Paulsen, S.W. Schill, T. St. John, C.J. Tams, J. Yackee

This book questions whether investment law influences the wider field of general international law, and more specifically, whether approaches adopted by tribunals in investment arbitrations have radiated, or should radiate, into other fields of international law.To answer this question, the book engages in a detailed analysis of pronouncements by investment tribunals on state responsibility, the law of treaties, and general principles of dispute resolution, and evaluates their impact beyond the narrow field of investment law. The perspectives provided in the book highlight how rules of general international law are concretised, specified, and at times moulded in investment arbitration practice. By doing so, the book enhances our understanding of the relationship between general international law and one its most dynamic sub-disciplines.Combining conceptual and practical perspectives, and offering a detailed analysis of the pertinent case law, the book is a plea for a fuller engagement directed at both general international lawyers and international investment lawyers. It will help investment lawyers better understand the role of general international law in their field of practice. General international lawyers will benefit from paying close attention to how investment lawyers apply and interpret rules of general international law.

This book develops a conceptual framework that captures not only the tensions between constitutional values that are common to liberal democracies – human rights, democracy, and the rule of law – and the investment treaty regime, but also the potential for co-existence and complementarity.Contributions from leading experts in the field address how different systems of constitutional law interact with the investment treaty regime. Chapters provide a detailed overview of the various forms of interaction, and critically engage with the competing claims for supremacy that constitutional law and international investment law formulate. The book also addresses the reactions within the investment treaty regime to the demands formulated by constitutional law, in particular the use of constitutional analogies to understand international investment law and investor-state dispute settlement.Investigating the leading questions and issues surrounding this growing topic, this book will be an ideal read for students and scholars interested in financial, economic, and international law. Practitioners of constitutional law will also benefit from this innovative book.

This collection of documents brings together a large number of primary sources on the peaceful settlement of disputes in a usable and affordable format. The documents included reflect the diverse techniques of international dispute settlement, as recognised in Articles 2(3) and 33 of the UN Charter, such as negotiation, mediation, arbitration and adjudication. The book comprises the most relevant multilateral treaties establishing dispute settlement regimes, as well as examples of special agreements, compromissory clauses, optional clause declarations and relevant resolutions of international organisations. It covers both diplomatic and adjudicative methods of dispute settlement and follows a basic division between general dispute settlement mechanisms, and sectoral regimes in fields such as human rights, WTO law, investment, law of the sea, environmental law and arms control. The book is the first widely-available collection of key documents on dispute settlement. It is aimed at teachers, students and practitioners of international law and related disciplines.

Volume 10 of the EYIEL focusses on the relationship between transnational labour law and international economic law on the occasion of the 100th anniversary of the International Labour Organisation (ILO). As one of the oldest UN Agencies, the ILO has achieved considerable progress with respect to labour rights and conditions. The contributions to EYIEL Volume 10 assess these achievements in light of current and future challenges. The ILO’s core instruments and legal documents are analysed and similarly the impact labour standards have on trade and investment agreements. In its regional section, EYIEL 10 addresses recent developments in the US and the EU, including the US’ trade policy strategy towards China as well as the reform of the NAFTA. In its part on institutions, EYIEL 10 focusses inter alia on the role of the rule of law in relation to current practices of the International Monetary Fund and of the WTO’s Appellate Body as an international court. Furthermore, it provides an overview of current cases before the WTO. Finally, the volume entails a section with review essays on recently published books in the field of international economic law and international investment law.

Volume 12 of the EYIEL focuses on “The Future of Dispute Settlement in International Economic Law”. While new forms of dispute settlement are emerging, others are in deep crisis. The volume starts off with reflections on Dispute Settlement and the World Trade Organisation, most prominently the crisis of the Appellate Body, but also addressing international intellectual property law and the African Continental Free Trade Area. This is followed by a section on Dispute Settlement and Investment Protection/International Investment Law, which includes articles on the summary dismissal of claims, the margin of appreciation doctrine, the use of conciliation to settle sovereign debt disputes, and contract-based arbitration in light of Achmea and Hagia Sophia at ICSID. Further contributions consider the emerging role of commercial courts, the dejudicialization of international economic law, dispute settlement in the UK-EU Withdrawal Agreement, reference mechanisms in dispute resolution clauses,and UNCLOS.

Through a mix of foundational inquiries and coverage of current issues (such as climate change litigation), the volume offers a rich and nuanced account of international economic law in an era of "Climate Change and Liability".

The focus of volume 14 of the EYIEL is on “(Public) Procurement and Competition Law in European and International Economic Law”. It is testimony to the fact that areas of law originally perceived as purely economic are permeated by the challenges of society today and adapting to these by embracing innovation, promoting sustainability and social responsibility and including new values in their legal constitutions. Thus, the focus section provides a broad spectrum of contributions considering the interaction between (public) procurement law and WTO law, the role of RTAs, the inclusion of sustainability aspects as well as the influence recent development and challenges such as the Covid-19 pandemic and climate change have on public procurement and competition policy.In its general section the EYIEL considers “Current Challenges, Developments and Events in European and International Economic Law”. It provides a cross-section of recent developments touching upon the Next Generation EU, food commodification, new regulatory approaches to geographical indications, the interaction between investment law and human rights as well as the newest developments with regard to Public-Private Partnership Legislation.

As global economic governance faces mounting challenges—from climate change to geopolitical shifts—the 2024 edition of EYIEL revisits the enduring debate of fragmentation vs.
