The strengths of international investment law - above all, a strong focus on investor interests and an effective adjudication and enforcement system - also entail its weaknesses: it runs the danger of impeding or even sanctioning the host states' legitimate regulatory interests and ignoring other fields of public international law. How does it cope with public interest concerns such as human rights, the environment or the fight against corruption? At the heart of this book lies a fresh approach towards a general theory of such global public interest considerations in the investment realm. Delineating how and why those considerations matter, and why the current system does not accommodate them properly, Andreas Kulick fleshes out general principles and customary international law as defences the host state may raise against alleged investor rights infringements and promotes proportionality as the appropriate balancing mechanism.

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.

Are conflicts between the ‘old capitalists’ and ‘new money’ manifest in today’s economy? Are investment treaties, which have traditionally been used to protect capital exporting states, now beginning to cause unwelcome side effects for them? International investment law has long been held as an economic and political instrument in the regime of international investment, with international investment treaties having been concluded to protect foreign investment and investors for a substantial period of time. However, the emerging new economic powers from the Third World are causing this to change. Taking the unique perspective of environmental protection in host states against states’ obligations to protect and promote foreign investments under the existing international investment treaty practice and dispute settlement practices, this book examines this inescapable conflict. This is the first major work in this field to interpret investment treaty provisions by introducing environmental reflection. It offers proposals for rethinking and reshaping the current pro-investor international investment law through taking up broad environmental exceptions.

Increasingly, transnational corporations, developed countries and private actors are broadening the boundaries of their investments into new territories, in search of a higher return on capital. This growth in direct foreign investment involves serious concerns for both the investor and host state. Various exponents of international civil society and non-governmental organisations persuasively claim that such growth in foreign investments constitutes potential and serious hazards both to the environment and the fundamental rights and freedoms of local populations. This book explores from an international law perspective the complex relationship between foreign investments and common concerns, i.e. values that do not coincide, or do not necessarily coincide, with the interests of the investor and of the host state. It pays particular attention to the role of the main international development banks in reconciling the needs of foreign investors with the protection of common concerns, such as the environment, human rights and labour rights. Among its collection of essays, the volume asks how much "regulatory space" investment law leaves; whether international investment law is an effective means of balancing contrasting interests, and whether investment arbitration currently constitutes a mechanism of global governance. In collecting the outlooks of various experts in human rights, environmental and international economic law, this book breaks new ground in exploring how attention to its legal aspects may help in navigating the relationship between foreign investment and common concerns. In doing so, the book provides valuable insights into the substantive issues and institutional aspects of international investment law.

This insightful and accessible introduction provides students and practitioners with a comprehensive overview of the increasingly important discipline of international investment law. Focusing primarily on the legal principles contained in the growing body of international investment agreements, this book covers the core concepts of the discipline, with attention given to their relation to each other and to the manner which they have developed through arbitration case law. The context of each legal principle is explored, along with a consideration of some of the major debates and emerging criticisms. Avoiding extensive case extracts, this book adopts an engaging and succinct narrative style which allows readers to advance their understanding of the topic while examining the legal principles with academic rigour and discerning commentary.

Das internationale Investitionsschutzrecht steht seit Jahren in der Kritik: Genießen Investoren internationale Rechte ohne korrespondierende Verantwortlichkeit? Dieses Buch stellt diese Sicht infrage. Vielmehr lassen sich der Vertrags- und Schiedspraxis bereits heute Investorenpflichten entnehmen, die das Buch normtheoretisch als direkte und indirekte Pflichten erschließt. Diese verpflichten Investoren etwa auf Menschenrechte und Umweltschutz. Sie sind potentiell geeignet, das Rechtsgebiet verstärkt auf das Ziel nachhaltiger Entwicklung auszurichten und Investorenverhalten international zu regulieren. Das Buch stellt diese Entwicklung in den allgemeineren Kontext der seit 1945 stattfindenden Individualisierung des Völkerrechts.
