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.

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.

This book is a thought-provoking and authoritative text on this fast moving field of international law.

A comprehensive source of information on four key issues: the definition of investor and investment; the interpretation of umbrella clauses in investment agreements; coverage of environmental, labour and anti-corruption issues; and the interaction between investment and services chapters in RTAs.

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.

A theoretical analysis of the structure of expropriation in investment law, investigating the foundations for contemporary scholarship and practice.

Due to the ongoing recent expansion of public interest issues worldwide, the state’s right to regulate has been recaptured as a prominent concept in international investment law. The fair and equitable treatment (FET) standard provision in the text of an international investment agreement (IIA) has become a detailed clause clarifying the specific obligations of a state towards an investor under the FET standard. However, striking the right balance between the interests of host states and investors in these new treaty formulations has proved to be challenging. This book greatly clarifies the field by offering the in-depth analysis of the application of the state’s right to regulate in relation to FET standard provisions in IIAs and to decisions by arbitral tribunals in FET cases. Recognising that the role of tribunals is to balance the state’s public interests and the interests of the investor when interpreting and applying the FET standard, the author pursues such seminal issues and topics as the following: the legitimacy of the objective of the state’s measure; obligations and responsibilities of investors towards a host state; the nature and impact of a change to a national regulatory framework; special economic and sociopolitical circumstances in a host state; and due diligence and risk assessment as a condition for the protection of an investor’s legitimate expectations. Multiple IIAs concluded by the OECD Member States, as well by Russia and China between the developing countries, and the prominent investment law cases on the FET standard are examined in detail. The analysis pays particular attention to how investment jurisprudence in FET cases has been reflected in such new IIAs as the Comprehensive Economic and Trade Agreement between the European Union (EU) and Canada (CETA), the EU-Vietnam FTA and the EU-Singapore FTA. These case studies demonstrate the evolution of the IIAs’ FET standard provisions and how they balance the application of the FET standard and the state’s right to regulate. Suggestions are provided for drafting formulations of the FET standard that can contribute to achieving such a balance. In the clear light it sheds on the legal conditions under which states may regulate in the public interest and its contribution to the reforms that are currently taking place in the field of international investment law, this book constitutes an exemplary framework to evaluate investment decisions on the FET standard and the right to regulate. It is sure to prove extremely useful for practitioners who work on investment cases, policymakers involved in negotiating and drafting of IIAs, policy advisors of governmental and non-governmental organisations and academics in international investment law.
