Stephan Schill is Professor of International and Economic Law and Governance at the Faculty of Law of the University of Amsterdam. He is also General Editor of the Yearbook Commercial Arbitration published by the International Council for Commercial Arbitration (ICCA), General Editor of ICCA Publications, and Co-Editor-in-Chief of The Journal of World Investment & Trade, one of the major journals in international economic law.
Professor Schill's research focuses on international investment law, investor-state dispute settlement, European Union law, and comparative public law. These fields have come together in his European Research Council-funded project on ‘Private-Public Arbitration as Transnational Regulatory Governance: Charting and Codifying the Lex Mercatoria Publica’ (see next tab for more information) and continue to mark his research.
Professor Schill has published extensively on international investment law and international dispute settlement, including its relations to other regimes of international law, European Union law, constitutional and administrative law, and commercial arbitration. Leading works include The Multilateralization of International Investment Law (Cambridge University Press 2009), as well as edited volumes on International Investment Law and Comparative Public Law (Oxford University Press 2010), International Investment Law and Development (Edward Elgar 2015) (with Christian Tams and Rainer Hofmann), Transnational Law of Public Contracts (Bruylant 2016) (with Mathias Audit), and International Investment Law and History (Edward Elgar 2018) (with Christian Tams and Rainer Hofmann). in 2022, the 3rd edition of Schreuer's Commentary on the ICSID Convention will appear Cambridge University Press, which Professor Schill is curating as General Editor and contrubuting to as an author.
Professor Schill also has practical experience in international law and dispute resolution. Being admitted to the bar in Germany (Rechtsanwalt) and in the State of New York (Attorney-at-Law), he serves as expert and arbitrator in international arbitrations under a variety of arbitral rules, including those of the International Centre for Settlement of Investment Disputes (ICSID) and the United Nations Commission on International Trade (UNCITRAL), has acted as counsel before the European Court of Human Rights, and advises governments and international organizations on international investment law and policy. Appointed by Germany, he is a Member of the ICSID Panel of Arbitrators.
The project analyzes the rising phenomenon of transnational arbitrations between private economic actors and public law bodies (private-public arbitrations) as a mechanism of global regulatory governance. Breaking with the prevailing view that arbitration is only a means to settle individual disputes, it hypothesizes that arbitrators themselves exercise public authority, mainly in two regards: first, by reviewing government acts as to their legality, and second, by incrementally making the rules that govern public-private relations. This takes place, it is hypothesized, rather independently of specific domestic legal systems and their democratic processes; arbitral tribunals, in other words, become important law-makers. The body of law they develop is what the project designates as “lex mercatoria publica” – in allusion to the a-national law generated by arbitral tribunals in international private-private disputes widely called “lex mercatoria”. Private-public arbitrations constitute a largely overlooked field of global regulatory governance even though it affects questions of central concern for the public interest. It affects states the world over and has an equally transformative effect for public governance as the europeanization and internationalization of public law. Against this background, the project will provide a comprehensive (historic, sociological, political, economic, and legal) perspective on private-public arbitration as governance and its legitimacy. It will describe and analyze the content of the lex mercatoria publica by empirically researching into the modern and historic practice of private-public arbitration and develop – mainly through comparative law research ‑ normative criteria to assess the legitimacy of private-public arbitration in democratic societies that are based on the rule of law.
Globalization fundamentally transforms the relationship between states as representatives and fiduciaries of the public interest and economic actors. What was once understood as a hierarchical relationship, characterized by the unilateral exercise of public authority through legislation, administration, and adjudication, increasingly gives way to varying forms of cooperation between the state and private actors, prompted by the privatization of public functions and increases in public-private-partnerships. This “cooperative paradigm” of state-market relations is precipitated not only by the Washington consensus and the voluntary retreat of the state, but by the increasing dependency of public bodies on private finance and expertise when providing public goods in infrastructure, energy, health, education, etc. It is a policy that is deeply enshrined, for example, in the EU, as reflected in the Europe 2020 strategy (see COM(2010)2020 and COM(2010)546). Public-private cooperation is further precipitated by the fact that domestic law and governance themselves become a negotiable commodity that is subject to competition between states in a globalized market. Competition in taxation, corporate law and corporate governance, environmental regulation, or labor standards are but a few examples that illustrate the dependency of states on acceptance by and cooperation with private economic actors.
The cooperative paradigm affects not only public policy- and decision-making through legislation and administration, but also challenges established ideas about adjudicating disputes between the state and private economic actors. Instead of being resolved in domestic courts, such disputes face pressure towards both internationalization and privatization. Thus, since the beginning of the 1990s we witness a considerable rise in alternative methods of dispute settlement, such as mediation and conciliation, but above all arbitration through party-appointed arbitrators who can settle disputes with binding force in place of the otherwise competent domestic courts. Such disputes are based both on international treaties that provide for the settlement of private-public disputes, above all under international investment treaties, but also on arbitration clauses in contracts between states or state entities and private economic actors.
This development is little problematic when arbitrations only involve private commercial actors. By contrast, when disputes between the state or state entities and private economic actors are involved, matters are fundamentally different. In such cases, fundamental principles of constitutional law – above all the principles of democracy and of the rule of law – are affected because government acts are controlled, and the concrete delineation of private rights and public interests is drawn, not by democratically legitimized domestic courts, but by party-appointed one-off arbitral tribunals. Arbitrations against Uruguay and Australia concerning plain packaging of cigarettes, against Germany’s nuclear power phase-out, against Argentina’s emergency legislation enacted to tackle the country’s 2001/2002 financial crisis, or against the United States, Canada, and Mexico concerning environmental or labor standards illustrate the significant public-policy implications of private-public arbitrations.
These public policy implications are all the more significant as arbitration proceedings do not conform to public law safeguards that are in place in public law adjudication at the domestic level, such as transparency of the proceedings, possibilities for third-party participation, limitations on damages as public law remedies, or the need for public law expertise of adjudicators. Instead, arbitration generally follows private law rationales, such as party autonomy and confidentiality of the proceedings. This is critical because arbitral tribunals do not only settle individual disputes, but increasingly become the preferred method of resolving disputes between the state and the private sector in important fields such as energy, public utilities, and infrastructure. Arbitration threatens to replace domestic courts in these matters, posing challenges for the concept of the rule of law. Two interrelated dangers exist: first, that the rise of arbitration results in the loss of jurisprudence and case law, an important public good necessary for legal certainty and legal security; and second, that arbitrations through one-off arbitral tribunals result in incoherent decisions, which equally threatens the predictability of how disputes between the state and private actors would be resolved. Both factors cast central tenets of the concept of the rule of law, and hence the legitimacy of private-public arbitration in general, into question. Furthermore, the rise of arbitration will have the inevitable effect that arbitral tribunals increasingly concretize and develop the normative foundations governing state-market relations. They may even redefine through their dispute settlement activity the relationship between private rights and public interests and bypass public policy choices made by democratically elected public authorities.
The rise of transnational private-public arbitration thus raises important issues as to its legitimacy. How are arbitrators in such proceedings legitimized? What powers do they, or should they have? What is their proper role when reviewing government acts? How do they actually decide cases and what is the appropriate normative framework to apply? Do they develop a uniform jurisprudence that is predictable or are their decisions incoherent and inconsistent? Is the consent of the disputing parties sufficient to legitimize private-public arbitrations or are farther-reaching transparent and democratic processes necessary as a source of legitimacy? Understanding what arbitrators do, according to which rationales they decide, and how they exercise power over states and state entities – in short: understanding how transnational private-public arbitration functions as a governance mechanism and answering to the legitimacy concerns it raises ‑ will be crucial for many areas of public-private cooperation and thus for the gestalt of the state-market relation and social order in a global market economy more generally.
It is these questions that the research project aims to answer by analyzing private-public arbitrations under investment treaties and public contracts, the substantive and procedural standards applied by arbitral tribunals, by looking in a comparative fashion at the normative framework set up by both domestic and international public law. Ultimately, this is hoped to lead to the formulation of both general principles regarding the conduct of private-public arbitrations as well as a restatement of the rules and principles applied by arbitral tribunals in private-public arbitrations. This analysis of the lex mercatoria publica should enable arbitrators, judges, and other international and national decision-makers to render more predictable, more circumspect, overall better, and fairer decisions concerning private-public arbitration. It will provide solid foundations for enhancing transnational private-public arbitration as an institution of global regulatory governance in the interest of better and more efficient cooperation between states and private economic actors in the global economy.
Since 2014, Stephan Schill is Editor-in-Chief of The Journal of World Investment & Trade (JWIT), one of the internationally leading journals on international economic law. Since 2019, he shares this responsibility with Hélène Ruiz Fabri of the Max Planck Institute Luxembourg. For more information on the Journal and for instructions on how to make submissions for publication please visit JWIT's homepage.
The Journal of World Investment & Trade is a double-blind peer-reviewed journal that focuses on the legal aspects of foreign investment relations in a broad sense. This encompasses the law of bilateral, multilateral, regional and sectoral investment treaties, investor-State dispute settlement, and domestic law relating to foreign investment, but also relevant trade law aspects, such as services, public procurement, trade-related investment measures, and intellectual property, both under the WTO framework and preferential trade agreements. In addition, the Journal aims to embed foreign investment law in its broader context, including its interactions with international and domestic law, both private and public, including general public international law, international commercial law and arbitration, international environmental law, human rights, sustainable development, as well as domestic constitutional and administrative law.
The Journal is institutionally independent and ideologically neutral. It is not attached to specific national jurisdictions, but has a global outreach. It covers both the mainstream of foreign investment law and investment law’s frontiers. It offers a place for the publication of scholarly studies dealing with fundamental and systematic problems of foreign investment relations and their solutions, but also welcomes analyses of current topics, such as international and domestic policy trends, relevant case law, and country- or industry-specific case studies, including in the natural resources and energy sectors. It is open to doctrinal analysis as well as theoretical, conceptual, and interdisciplinary approaches, including law and economics analysis, empirical analysis, historical analysis, political science analysis, or normative analysis. It aims to address scholars, government officials, members of international and non-governmental organizations, and legal practitioners in both capital-exporting and capital-importing countries.
