This book reviews for the first time some of the less frequently addressed actors in international investment law. Traditional studies concerning actors in international investment law have tended to focus on arbitrators, claimant investors and respondent states. This book explores transnational actors, such as UNCITRAL, the EU, international standardizing bodies, domestic and international courts and tribunals, etc., shedding light on their transnational activity and pluralistic role in international investment law.

This open access book focuses on public actors with a role in the settlement of investment disputes. Traditional studies on actors in international investment law have tended to concentrate on arbitrators, claimant investors and respondent states. Yet this focus on the "principal" players in investment dispute settlement has allowed a number of other seminal actors to be neglected. This book seeks to redress this imbalance by turning the spotlight on the latter. From the investor's home state to domestic courts, from sub-national governments to international organisations, and from political risk insurance agencies to legal defence teams in national ministries, the book critically reviews these overlooked public actors in international investment law.

The role and position of non-state actors in international law is the subject of a long-standing and intensive scholarly debate. This book explores the participation of this new category of actors in an international legal system that has historically been dominated by states. It explores the most important issues, actors and theoretical approaches with respect to these new participants in international law. It provides the reader with a comprehensive and state-of-the-art overview of the most important legal and political developments and perspectives. Relevant non-state actors discussed in this volume include, in particular, international governmental organisations, international non-governmental organisations, multinational companies, investors and armed opposition groups. Their legal position is considered in relation to specific issue-areas, such as humanitarian law, human rights, the use of force and international responsibility. The main legal theories on non-state actors' position in international law – neo-positivism, the policy-oriented approach and transnational law – are covered at the beginning of the book, and the essential political science perspectives – on non-state actors' role in international politics and globalisation, as well as their soft power – are presented at the end.

A comprehensive compendium for the field of transnational law by providing a treatment and presentation in an area that has become one of the most intriguing and innovative developments in legal doctrine, scholarship, theory, as well as practice today. With a considerable contribution from and engagement with social sciences, it features numerous reflections on the relationship between transnational law and legal practice.

The interplay between human rights and international investment law and arbitration is a relatively recent field of enquiry, both on the academic and policy levels. But the role and responsibility of corporations in respecting human rights when they invest or operate other activities abroad has been on the international agenda since long. While the vast majority of international investment treaties do not mention human rights, States have since recently effectively included references to human rights norms in their treaties. Also, several recent cases have taken up human rights of foreign investors as part of a counterclaim raised by the host State of the foreign investment, thus showing an increased infiltration of human rights into investment law and arbitration. In this chapter, we discuss the position of foreign investors, as non-State actors, in international investment law and arbitration. We also address the question whether human rights law directly impose obligations on foreign investors as a matter of international law.

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.

Addresses the most central debates in contemporary investment law and policy.
