General principles of law play an important role in investment arbitraion and can be applied by a tribunal when no treaty provision or rule of customary international law exists regarding a particular issue. They can be used in traditional means, such as the interpretation of vague treaty terms, or for wider reaching issues emerging from the international legal order. Following a significant increase in references to the general principles of law by Investor-State tribunals questions have been raised around the meaning and function of these principles. Written by an expert in the field this book offers clear and comprehensive guidelins to better understand the nature, meaning, and function of general principles of law in the field of international investment law. Applying these principles to practice, this book assesses 17 concepts and notions in the field of investment arbitration, providing counsel and arbitrators with clear guidance on what should, and should not, be considered a general principle of law.

Rules of customary international law provide basic legal protections to foreign investors doing business abroad. These rules remain of fundamental importance today despite the growing number of investment treaties containing substantive investment protection. In this book, Patrick Dumberry provides a comprehensive analysis of the phenomenon of custom in the field of international investment law. He analyses two fundamental questions: how customary rules are created in this field and how they can be identified. The book examines the types of manifestation of state practice which should be considered as relevant evidence for the formation of customary rules, and to what extent they are different from those existing under general international law. The book also analyses the concept of states' opinio juris in investment arbitration. Offering guidance to actors called upon to apply customary rules in concrete cases, this book will be of significant importance to those involved in investment arbitration.

Marcelo Kohen and Patrick Dumberry explore in an article-by-article commentary the Resolution adopted in 2015 by the Institute of International Law, on state succession in matters of state responsibility. They analyse the content and scope of application of each provision based on a comprehensive survey of existing state practice and judicial decisions (both domestic and international), as well as taking into account the works of scholars and that of the ILC Special Rapporteur in his proposed Draft Articles on the same topic. This book explains the rationale and the reasons behind why the Institute adopted specific solutions to address particular problems of succession to responsibility for each provision, including the need to achieve a fair outcome given the specific circumstances and relevant factors for each case.

This book analyses all relevant questions of State responsibility and attribution arising from the conduct of rebels and governments in the context of civil wars and rebellions aiming at the establishment of a new government or the creation of a new State. Based on a comprehensive analysis of both old and recent State practice, and case law, including investment awards, as well as the works of scholars and the International Law Commission, the book identifies ten basic rules which can be used by States and international tribunals. It explains the history, content and scope of application of the specific solutions adopted in Article 10 of the International Law Commission Articles on State responsibility to address particular problems. The book also critically revisits some of the solutions that have been put forward by tribunals and scholars, and examines a number of questions which have never been addressed by them before.

A Guide to State Succession in International Investment Law is the first work of its kind to provide a comprehensive analysis of State succession issues arising in the context of international investment law. The book examines the legal consequences in the field of investor-State arbitration arising from the disappearance or the creation of a State, or from a transfer of territory between States. Specifically, it analyses whether a successor State is bound by the investment treaties (bilateral and multilateral) and the State contracts which had been signed by the predecessor State before the event of succession.Key features include:• Much-needed examination of the practice of States in the context of succession to bilateral, multilateral treaties and State contracts• comprehensive and up-to-date analysis of international arbitration cases involving issues of State succession• practical guidance on the application of Rules of State succession in investment arbitration cases, including when succession occurs during arbitral proceedings • assessment of the theoretical reasoning behind previously unexplored issues in State succession.Actors who are called upon to apply Rules of State succession in investment arbitration cases will find this book a valuable source of practical guidance. Researchers in the field of international investment law will also find this to be a compelling text, with strong theoretical foundations.

The fair and equitable treatment (‘FET’) standard is a type of protection found in BITs which has become in the last decades one of the most controversial provisions examined by arbitral tribunals. This book first examines the interaction between the ‘minimum standard of treatment’ (MST) and the FET standard and the question why States started referring to the former in their BITs. It also addresses the question whether the FET should be considered as an autonomous standard of protection under BITs. This book also examines the controversial proposition that the FET standard should now be considered as a rule of customary international law. I will show that while the practice of States to include FET clauses in their BITs can be considered as general, widespread and representative, it remains that it is not uniform and consistent enough for the standard to have crystallised into a customary rule. States also lack the necessary opinio juris when including the clause in their BITs.

In the context of the break-up of the Soviet Union and Yugoslavia, the independence of Montenegro and the unification of Germany, can a new State be held responsible for wrongful acts committed before its independence by the predecessor State? This book is the most comprehensive analysis of State practice, case law and scholarship identifying the factors and circumstances under which the rights and obligations arising from wrongful acts committed before independence can be transferred to a new State. This updated and revised second edition covers new developments, including the recent works of the International Law Commission and the Institute of International Law.
