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.

International investment law is one of fastest-growing areas of international law, but it is plagued by the vagueness of many investors' rights and unpredictable investment tribunal decisions. This books analyses international investment law through the lens of comparative public law to clarify investment treaty obligations and arbitral procedure.

This important book examines the development of soft law instruments in international investment law and the feasibility of a 'codification' of the present state of this field of international economic law. It draws together the views of international experts on the use of soft law in international law generally and in discrete fields such as WTO, commercial, and environmental law. The book assesses whether investment law has sufficiently coalesced over the last 50 years to be 'codified' and focuses particularly on topical issues such as most-favoured-nation treatment and expropriation. This timely book will appeal to academics interested in the development of international law and legal theory, to those working in investment law, Government investment treaty negotiators and arbitration practitioners.

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.

'...This book [...] goes beyond stating what the law is and focuses on controversies occurring within this area of the law... an excellent introduction to this complex area of international law for newcomers to the subject' Kate Miles, Australian International Law Journal The updated edition of this acclaimed book offers a critical overview of the law of foreign investment, incorporating a thorough analysis of the principles and standards of treatment available to foreign investors in international law. It is authoritative and multi-layered, offering an analysis of the key issues and an insightful assessment of recent trends in the case law, from both developed and developing country perspectives. A major feature of the book is that it deals with the tension between the law of foreign investment and other competing principles of international law. In doing so, it proposes ways of achieving a balance between these principles and the need to protect the legitimate rights and expectations of foreign investors on the one hand, and the need not to restrict unduly the right of host governments to implement their public policy on the other, including the protection of the environment and human rights, and the promotion of social and economic justice within the host country. Many of the pioneering ideas that were advanced in the first edition of this book have been taken up by governments and international organisations in their attempts to reform the investor-State dispute settlement mechanism and strike a balance between different competing principles in developing international investment law. Accordingly, this fifth edition captures the essence of the ongoing multiple reform processes – either planned or envisaged – currently underway.
