This volume celebrates the first fifty years of the International Centre for Settlement of Investment Disputes (ICSID) by presenting the landmark cases that have been decided under its auspices. These cases have addressed every aspect of investment disputes: jurisdictional thresholds; the substantive obligations found in investment treaties, contracts, and legislation; questions of general international law; and a number of novel procedural issues. Each chapter, written by an expert on the chapter’s particular focus, looks at an international investment law topic through the lens of one or more of these leading cases, analyzing what the case held, how it has been applied, and its overall significance to the development of international investment law. These topics include: - applicable law; - res judicata in investor-State arbitration; - notion of investment; - investor nationality; - consent to arbitration; - substantive standards of treatment; - consequences of corruption in investor-State arbitration; - State defenses - counter-claims; - assessment of damages and cost considerations; - ICSID Arbitration Rule 41(5) objections; - mass claims, consolidation and parallel proceedings; - provisional measures; - arbitrator challenges; - transparency and amicus curiae; and - annulment. Because the law of international investment continues to grow in importance in an ever globalizing world, this book is more than a fitting way to mark the past fifty years and to welcome the next fifty years of development. It will prove both educational for practitioners new to the field and informative for seasoned investment lawyers. Moreover, the book itself is a landmark that will be of great value to professionals, scholars and students interested in international investment law.

In the last decade, international investment law has developed into one of the core areas of international law. The reason for this development is twofold. The number of cases has increased rapidly. The International Centre for Settlement of Investment Disputes has over a hundred pending cases and there are more before ad hoc tribunals, mostly operating under the United Nations' Commission on International Trade Law Rules. In addition, investment law has addressed a number of novel issues while also coming up with some innovative solutions. This book brings together the papers delivered at the Young Scholars Conference in International Economic Law, which was held at the University of Vienna Law School in June 2007. Under the general topic of "Current Issues and Developments in International Investment Law," the speakers addressed core issues like the definition of investment, legitimate expectations of investors, and the meaning and importance of references to domestic law included in many Bilateral Investment Treaties. Also discussed were topics like the role of investment law in the context of the European Union and its relation to cultural matters, human rights, and other non-investment issues. As international investment law is becoming more and more significant, a book such as this, dedicated to the latest developments in the field, will be of utmost importance to anyone interested in this area of law.

This up-to-date and revised third edition offers a clear and comprehensive overview aimed at upper-level undergraduate and postgraduate courses on international investment law. Key features and benefits include: • concise descriptions of legal principles followed by classic and contemporary cases • extracts from and analysis of key recent decisions, revised investment treaty texts and new court system proposals • detailed discussion notes and all new ‘Questions to an Expert’ to enable classroom discussion and facilitate critical reflection.

International investment law is one of the fastest growing areas of international law. It has led to the signing of thousands of agreements, mostly in the form of investment contracts and bilateral investment treaties. Also, in the last two decades, there has been an exponential growth in the number of disputes being resolved by investment arbitration tribunals. Yet the legal principles at the basis of international investment law and arbitration remain in a state of flux. Perhaps the best illustration of this phenomenon is the wide disagreement among investment tribunals on some of the core concepts underpinning the regime, such as investment, property, regulatory powers, scope of jurisdiction, applicable law, or the interactions with other areas of international law. The purpose of this book is to revisit these conceptual foundations in order to shed light on the practice of international investment law. It is an attempt to bridge the growing gap between the theory and the practice of this thriving area of international law. The first part of the book focuses on the 'infrastructure' of the investment regime or, more specifically, on the structural arrangements that have been developed to manage foreign investment transactions and the potential disputes arising from them. The second part of the book identifies the common conceptual bases of an array of seemingly unconnected practical problems in order to clarify the main stakes and offer balanced solutions. The third part addresses the main sources of 'regime stress' as well as the main legal mechanisms available to manage such challenges to the operation of the regime. Overall, the book offers a thorough investigation of the conflicting theoretical positions underlying international investment law, testing their worth by reference to concrete issues that have arisen in the jurisprudence. It demonstrates that many of the most important practical questions arising in practice can be addressed by a carefully dosed resort to theory.

Transnational investment involves a variety of actors (States, public and private legal entities, and natural persons) whose relationships are governed by rules and legal instruments belonging to different legal systems. This book provides a systematic study of the sources of rights and obligations in the field of transnational investment, and their coordination and interaction. It focuses primarily on the network of over 3,000 Bilateral Investment Treaties, international investment contracts, customary international law, the main multilateral treaties, national legislation, international case law and general principles of law. The book, firmly based on State practice, arbitral awards and national decisions, is indispensable to fully appraise the nature and content of the claims of private investors as well as to identify the law applicable in investment arbitration.

This open access book focuses on public actors with a role in the settlement of investment disputes. Traditional studies on actors in international investment law have tended to concentrate on arbitrators, claimant investors and respondent states. Yet this focus on the "principal" players in investment dispute settlement has allowed a number of other seminal actors to be neglected. This book seeks to redress this imbalance by turning the spotlight on the latter. From the investor's home state to domestic courts, from sub-national governments to international organisations, and from political risk insurance agencies to legal defence teams in national ministries, the book critically reviews these overlooked public actors in international investment law.

International investment law is in transition. Whereas the prevailing mindset has always been the protection of the economic interests of individual investors, new developments in international investment law have brought about a paradigm shift. There is now more than ever before an interest in a more inclusive, transparent, and public regime. Shifting Paradigms in International Investment Law addresses these changes against the background of the UNCTAD framework to reform investment treaties. The book analyses how the investment treaty regime has changed and how it ought to be changing to reconcile private property interests and the state's duty to regulate in the public interest. In doing so, the volume tracks attempts in international investment law to recalibrate itself towards a more balanced, less isolated, and increasingly diversified regime. The individual chapters of this edited volume address the contents of investment agreements, the system of dispute settlement, the interrelation of investment agreements with other areas of public international law, constitutional questions, and new regional perspectives from Europe, South Africa, the Pacific Rim Region, and Latin America. Together they provide an invaluable resource for scholars, practitioners, and policymakers.
