The past two decades have seen a significant proliferation of trade and investment treaties around the world. States are increasingly negotiating agreements that regulate both trade and investment, such as the Trans-Pacific Partnership Agreement and the Transatlantic Trade and Investment Partnership. The number of investor-state dispute settlement cases is growing dramatically each year, yet states' enthusiasm for investor-state arbitration has become more qualified as concern has intensified that the system can be abused by foreign investors. Good faith is therefore becoming increasingly important as a principle, particularly in the investment context, due to disputes about investor conduct such as corporate restructuring in order to gain the protection of a particular investment treaty regarding an existing or foreseeable dispute, and States' responses to public policy concerns through attempts to modify or terminate investment treaties in the face of ongoing or expected claims. Tribunals adjudicating investment disputes have used the principle of good faith in a haphazard and uncoordinated manner, causing serious problems of uncertainty and inconsistency. In response to these developments, this book contains the first comprehensive and integrated analysis of the treatment of good faith in international investment law, noting the broader implications of good faith in public international law and international trade law.

Good Faith in International Investment Arbitration offers a comprehensive study on both the theory and application of the principle of good faith in the international arbitration process. It is an essential book for both practitioners and academics.

The Handbook of International Investment Law and Policy is a one-stop reference source. This Handbook covers the main conceptual questions in a logical, scholarly yet easy to comprehend manner. It is based on a truly global vision insisting particularly on Global South related issues and developments. In this respect, the Handbook of International Investment Law and Policy provides an excellent modern treatment of international investment law which is one of the fastest growing areas of international economic law. Professor Julien Chaisse, Professor Leïla Choukroune, and Professor Sufian Jusoh are the editors-in-chief of the Handbook of International Investment Law and Policy, a 1,500-page reference book, which is anticipated becoming one of the most influenced reference books in the international economic law areas. This Handbook is a highly comprehensive set of four volumes of original materials designed to cover all facets of international investment law and policy. The chapters, written by world-leading experts, explore key ideas and debates in relation to: international investment substantive law (Volume I), Investor-state dispute settlement (Volume II); interaction between international investment law and other fields of international law (Volume III); and, the new trends and challenges for international investment law (Volume IV). The Handbook will feature more than 80 contributions from leading experts (academics, lawyers, government officials), including Vivienne Bath, M. Sornarajah, Mélida Hodgson, Rahul Donde, Roberto Echandi, Andrew Mitchell, Ernst-Ulrich Petersmann, Christina L. Beharry, Krista Nadakavukaren Schefer, Leon Trakman, Prabhash Ranjan, Emmanuel Jacomy, Mariel Dimsey, Stavros Brekoulakis, Romesh Weeramantry, Nathalie Bernasconi-Osterwalder, David Collins, Damilola S. Olawuyi, Katia Fach Gomez, Jaemin Lee, Alejandro Carballo-Leyda, Patrick W. Pearsall, Mark Feldman, Surya Deva, Luke Nottage, Rafael Leal-Arcas, James Nedumpara, Rodrigo Polanco, etc. This Handbook will be an essential reference tool for students and scholars of international economic law. Policy makers and researchers alike will find the Handbook of International Investment Law and Policy useful for years to come.

Drawing on a large and varied body of judicial and arbitral case law, this book provides a comprehensive, original, and up-to-date account of the role of equity in international law.

The rules of treaty interpretation codified in the 'Vienna Convention on the Law of Treaties' now apply to virtually all treaties, in an international context as well as within national legal systems, where treaties have an impact on a large and growing range of matters. The rules of treaty interpretation differ somewhat from typical rules for interpreting legal instruments and legislation within national legal systems. Lawyers, administrators, diplomats, and officials at international organisations are increasingly likely to encounter issues of treaty interpretation which require not only knowledge of the relevant rules of interpretation, but also how these rules have been, and are to be, applied in practice. Since the codified rules of treaty interpretation came into decree, there is a considerable body of case-law on their application. This case-law, combined with the history and analysis of the rules of treaty interpretation, provides a basis for understanding this most important task in the application of treaties internationally and within national systems of law. Any lawyer who ever has to consider international matters, and increasingly any lawyer whose work involves domestic legislation with any international connection, is at risk nowadays of encountering a treaty provision which requires interpretation, whether the treaty provision is explicitly in issue or is the source of the relevant domestic legislation. This fully updated new edition features case law from a broader range of jurisdictions, and an account of the work of the International Law Commission in its relation to interpretative declarations. This book provides a guide to interpreting treaties properly in accordance with the modern rules.

Good faith is a doctrine that is readily accepted in legal systems. Yet, its distinct meaning has always been elusive. Ideas such as justice and equity are omnipresent in the law. Good faith is counted among such ideas. Their function has been to provide a corrective approach in situations where the strict application of the law has unacceptable results. They are also used to support a decision-maker's conclusions on difficult issues where other solutions are equally possible. In these situations, good faith and similar ideas become rationalizations for the results arrived at. Defined or explained in this way, their existence in the law may be desirable. But put differently, these nebulous doctrines exist in the law to aid in finding subjective solutions to difficult issues, which may come to be justified through the use of such lofty notions. The latter conclusion immediately invites the criticism that the doctrine of good faith is capable of manipulation in order to justify a variety of inconsistent results. Critics argue that the subjectivity inherent in these concepts makes their use of doubtful significance. They have such a variable meaning that they could be used to support a variety of conclusions and befuddle the law in its search for certainty. Having in itself no power to lead to conclusions, the purpose of a concept such as good faith may be misguided: that of justifying conflicting solutions to difficult problems. This book demonstrates the range of scholarly views applicable to good faith in international investment law and the questions that remain to be answered.

Analysing how arbitral tribunals have dealt with the value judgment at the core of the distinction between 'objectionable' and 'unobjectionable' treaty shopping, this book suggests how States could reform their international investment agreements in order to make them less susceptible to the practice of treaty shopping.

A comprehensive insight into the legal framework of international economic relations, comprising the law of the World Trade Organization, investment law, and international monetary law, this book highlights the context of human rights, good governance, environmental protection, development, and the role of the G20 and multinationals.
