An examination of the origins of international investment law and their continued resonance in the twenty-first century.

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.

This book outlines the principles behind the international law of foreign investment. The main focus is on the law governed by bilateral and multilateral investment treaties. It traces the purpose, context, and evolution of the clauses and provisions characteristic of contemporary investment treaties, and analyses the case law, interpreting the issues raised by standard clauses. Particular consideration is given to broad treaty-rules whose understanding in practice has mainly been shaped by their interpretation and application by international tribunals. In addition, the book introduces the dispute settlement mechanisms for enforcing investment law, outlining the operation of Investor-State arbitration. Combining a systematic analytical study of the texts and principles underlying investment law with a jurisprudential analysis of the case law arising in international tribunals, this book offers an ideal introduction to the principles of international investment law and arbitration, for students, scholars, and practitioners alike.

Historiographical approaches in 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 methods in historical research can lead to a better understanding of international investment law.

This comprehensive book provides a complete overview of the international legal system of foreign investment protection, synthesising material from treaties, general international law, contracts and case law to demonstrate a coherent system of investment protection. Through this systematic approach, the book considers all aspects of the discipline, providing a thorough and accessible analysis.

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 book provides a conceptual and legal analysis of the core of investment protection guarantees that emerge from international treaties signed since 1959 for the promotion and protection of foreign investment. It focuses on both the origin and evolution of investment treaty standards. Beginning with origins, the work considers the broader context at the time when the first modern investment treaty was concluded. It goes on to examine the many decisions of ad hoc arbitral tribunals that have since been called upon to apply these treaties in order to resolve the several hundred investor-State disputes. It also looks at some of the recent investment treaties that have attempted to clarify and/or reform the content and scope of investment protection guarantees. Federico Ortino posits that the key investment protection provisions in investment treaties, and thus much of the controversy associated with such treaties, revolve around three concepts: legal stability, investment's value, and reasonableness. He argues that, from the very beginning, the protections afforded to foreign investments by modern investment treaties have been exceptionally broad, and as such restrictive of host States' ability to regulate. And whilst a growing number of investment treaty tribunals, as well as new investment treaties, have to some extent reined in such broad protections, the evolution of key investment protection standards has been marred by inconsistency and uncertainty.

The book focuses on the substantive protections accorded to investors and investments and on the variations among jurisdictions. Among the many specific issues and topics that arise in the course of the discussion are the following: - problems of transparency and conflict of interest; - the recent growth in IIAs between and among developing nations; - the effect of new model bilateral investment treaties (BITs); - the ability of non-disputing parties to participate in investor-state arbitration; - theories of the interaction of foreign direct investment (FDI) and BITs; - investor-state arbitration as an evasion of public regulatory authority; - the role of investment funds in international investment; - 'fork in the road' provisions; and - institutional versus ad hoc arbitration. International business and other investors will greatly appreciate the in-depth information and insightful guidance in this solidly useful book. It will also be welcomed by jurists and students as a significant milestone in the development of principles in a quickly growing field of practice that is still plagued with inconsistencies.

In The Interpretation of International Investment Law: Equality, Discrimination and Minimum Standards of Treatment in Historical Context, author Todd Weiler demonstrates how historical analysis should be adopted in the interpretation of international investment law obligations. Weiler subjects some of the most commonly held beliefs about the nature and development of international investment law to a critical re-appraisal, based upon meticulously assembled historical record. In the process, the book provides readers with a fresh perspective on some of the oldest obligations in international law.
