This new edition of what has rapidly become the pre-eminent work on the role of municipal law in investment treaty arbitration is justified not only by the accelerating appearance of investment treaty awards but also by the continuing, serious flaws in the application of international law by investment treaty arbitral tribunals. As a matter of international law, arbitrators need to be attentive to the circumstances where municipal law supplies the necessary substantive legal rule. They will find this book to be the best guide to this complex challenge. The author has maintained the overall structure of the first edition and added a new chapter on Article 42 of the ICSID Convention. Certain descriptions and arguments have been rethought and revised to clarify their significance and their applicability. The treatment focuses on the role of municipal law in providing the substance for concepts such as contracts, property rights, and shareholders’ rights, which are relevant in the international investment treaty context but are not regulated under international law. Among the complex questions considered are the following: - If the application of international law requires a renvoi to municipal law, how should that renvoi be conducted? - In investment disputes, what role, if any, should municipal law have in assessing State attribution under international law? - Should shareholders receive compensation for damages suffered by their company due to a violation of an international obligation vis-à-vis the company? - Does a contractual right exist to foreign investment ‘property’? - Under what conditions may a violation of municipal law become internationally wrongful? - May foreign investors rely on ‘expectations’ as an autonomous source of rights in investment treaty disputes? - Does an alleged breach of an umbrella clause transform a breach of contract claim covered by municipal law into an international law claim? The chapters answer these and many other questions in extraordinary depth, drawing on detailed analyses of the issues and implications posed by major relevant cases and arbitral decisions. The author’s analysis of the unavoidable interaction of municipal law and international law in investment treaty arbitration – and the consequences stemming from rejecting the application of municipal law when relevant – will continue to prove of immeasurable value to arbitrators, arbitration counsel, corporate counsel, and scholars of international law.

What is the relationship between politics and international law? Inspired by comparative politics and socio-legal studies, this Research Handbook develops a novel framework for comparative analysis of politics and international law at different stages of governance and in different governance systems. It applies the framework in a wide range of fields—from human rights and environmental standards, to cyber conflict and intellectual property—to show how the relationship between politics and international law varies depending on the sites where it unfolds.

The Oxford ILDC online database, an online collection of domestic court decisions which apply international law, has been providing scholars with insights for many years. This ILDC Casebook is the perfect companion, introducing key court decisions with brief introductory and connecting texts. An ideal text for practitioners, judged, government officials, as well as for students on international law courses, the ILDC Casebook explains the theories and doctrines underlying the use by domestic courts of international law, and illustrates the key importance of domestic courts in the development of international law.

General Principles and the Coherence of International Lawprovides a collection of intellectually stimulating contributions from leading international lawyers to the discourse on the role of general principles in international law. Offering a comprehensive analysis of the doctrines, practices, and debates on general principles of law, the volume assesses their role in safeguarding the coherence of the international legal system. This important book addresses the relationship between principles of law and the other sources of international law, explores the interplay between principles of law and domestic and regional legal systems and the role of principles of law with regard to three specific regimes of international law: investment law, human rights law and environmental law.

International Law is both an introduction to the subject and a critical consideration of its central themes and debates. The opening chapters of the book explain how international law underpins the international political and economic system by establishing the basic principle of the independence of States, and their right to choose their own political, economic, and cultural systems. Subsequent chapters then focus on considerations that limit national freedom of choice (e.g. human rights, the interconnected global economy, the environment). Through the organizing concepts of territory, sovereignty, and jurisdiction the book shows how international law seeks to achieve an established set of principles according to which the power to make and enforce policies is distributed among States.

"The Role of the Domestic Law of the Host State in Determining the Jurisdiction ratione materiae of Investment Treaty Tribunals: The Partial Revival of the Localisation Theory?" focuses on the largely unexplored role of the host state law in determining the jurisdiction ratione materiae of investment treaty tribunals. Given domestic law's essential role in subject-matter jurisdiction issues, and in the light of the broader function of host state law and host state courts in contemporary investment treaty law, the author argues that the dormant "localisation" theory that was raised and defended by developing countries in the 1960s-1970s in the context of foreign investment contract disputes has now been partially revived in the area of investment treaty law. This is a significant milestone in the ongoing discussions on the reform of investment treaty dispute settlement regime"--

Article 38 of the Statute of the International Court of Justice defines "international law" to include not only "custom" and "convention" between States but also "the general principles of law recognized by civilized nations" within their municipal legal systems. In 1953, Bin Cheng wrote his seminal book on general principles, identifying core legal principles common to various domestic legal systems across the globe. This monograph summarizes and analyzes the general principles of law and norms of international due process, with a particular focus on developments since Cheng's writing. The aim is to collect and distill these principles and norms in a single volume as a practical resource for international law jurists, advocates, and scholars. The information contained in this book holds considerable importance given the growth of inter-state intercourse resulting in the increased use of general principles over the past 60 years. General principles can serve as rules of decision, whether in interpreting a treaty or contract, determining causation, or ascertaining unjust enrichment. They also include a core set of procedural requirements that should be followed in any adjudicative system, such as the right to impartiality and the prohibition on fraud. Although the general principles are, by definition, basic and even rudimentary, they hold vital importance for the rule of law in international relations. They are meant not to define a rule of law, but rather the rule of law.
