Exploring the role of the International Court of Justice in the re-convergence of international law, this book contends that the court's jurisprudence is transforming traditional concepts such as sovereignty, rights and jurisdiction and in so doing is leading a trend towards the reunification of international law.

This major extension of existing scholarship on the fragmentation of international law utilises the concept of 'regimes' from international law and international relations literature to define functional areas such as human rights or trade law. Responding to existing approaches, which focus on the resolution of conflicting norms between regimes, it contains a variety of critical, sociological and doctrinal perspectives on regime interaction. Leading international law scholars and practitioners reflect on how, in situations of diversity and concurrent activity, such interaction shapes and controls knowledge and norms in often hegemonic ways. The contributors draw on topical examples of interacting regimes, including climate, trade and investment regimes, to argue for new methods of regime interaction. Together, the essays combine approaches from international, transnational and comparative constitutional law to provide important insights into an issue that continues to challenge international legal theory and practice.

This Festschrift is published on the occasion of Gerhard Hafner’s 65th birthday and his retirement as a professor at the University of Vienna. It assembles a great number of renowned friends and colleagues in international law honouring Gerhard Hafner’s outstanding career as scholar, diplomat, legal adviser and arbitrator. The diversity of areas selected for this Festschrift reflects the generalist approach of Gerhard Hafner towards international law. Among the topics on which his contribution was particularly influential are the fragmentation of international law, the law of State immunity and international criminal law, which feature prominently in the Festschrift. Other areas covered are the theory of international law (including sources), basic principles of international law, codification of international law, subjects of international law, international dispute settlement, the law of the sea and international environmental law, human rights and humanitarian law and the law of the European Union.

This book explores the effects of institutional fragmentation in international human rights law, by comparing the rights jurisprudence of three human rights courts and bodies, namely the European Court for Human Rights, the Inter-American Court for Human Rights and the Human Rights Committee. Contributions cover the areas of freedom of expression (journalism and the media), right to privacy, freedom of assembly and freedom of association (political parties), and measure the extent of fragmentation of human rights protection. Moreover, the volume argues that, while the conflict of laws approach, favoured by the International Law Commission, might work in avoiding outright conflict in obligation, in practice it is not an approach that presents a viable research agenda when it comes to understanding the causes and consequences of institutional fragmentation. This is especially evident in areas like international human rights, where the possibility of a silent drift between the jurisprudence of the three courts is a real possibility. This book was originally published as a special issue of the Nordic Journal of Human Rights.

The current system of international law is experiencing profound transformations. Indeed, the simultaneous processes of globalization combined with the disintegration of international systems of governance and law-making pose complex challenges for legal scholarship. The doctrinal response to these challenges has been theorized within two seemingly contradictory discourses in international law: fragmentation and constitutionalisation. This book takes an innovative approach to international law, viewing the processes of the fragmentation and constitutionalisation as being profoundly interconnected and reflective of each other. It brings together a select group of contributors, including both established and emerging scholars and practitioners, in order to explore the ways in which the problems of fragmentation and constitutionalisation are viscerally linked one to the other and thus mutually conditioning and stimulating. The book considers the theory and practice of international law looking at the two phenomena in relation to the various fields of international law such as international criminal law, cultural heritage law and international environmental law.

In The Right to Food and the World Trade Organization’s Rules on Agriculture: Conflicting, Compatible, or Complementary?, Rhonda Ferguson explores the relationship between the human right to food and agricultural trade rules. She questions whether States can adhere to their obligations under both regimes simultaneously. These two regimes are frequently portrayed to be in tension with one another. The content and contours of the right to food under international human rights law and WTO rules on domestic supports, export subsidies, and market access are considered through the lens of norm conflict theories. The analysis is situated within the context of the debate surrounding the fragmentation of international law.

Do WMD non-proliferation treaties comprise a special regime in international law, with rules that differ from general international law?

In recent decades there has been a considerable growth in the activities of international tribunals and the establishment of new tribunals. Furthermore, supervisory bodies established to control compliance with treaty obligations have adopted decisions in an increasing number of cases. National courts further add to the practice of adjudication of claims based on international law. While this increasing practice of courts and supervisory bodies strengthens the adjudicatory process in international law, it also poses challenges to the unity of international law. Most of these courts operate within their own special regime (functional, regional, or national) and will primarily interpret and apply international law within the framework of that particular regime. The role of domestic courts poses special challenges, as the powers of such courts to give effect to international law, as well as their actual practice in applying such law, largely will be determined by national law. At the same time, both international and national courts have recognised that they do not operate in isolation from the larger international legal system, and have found various ways to counteract the process of fragmentation that may result from their jurisdictional limitations. This book explores how international and national courts can, and do, mitigate fragmentation of international law. It contains case studies from international regimes (including the WTO, the IMF, investment arbitration and the ECtHR) and from various national jurisdictions (including Japan, Norway, Switzerland and the UK), providing a basis for conclusions to be drawn in the final chapter.

At a time when nearly all armed conflicts are related to self-determination, and frequently to claims for secession, this meticulous study examines the legal issues at stake in the light of the existence of European micro-States: Liechtenstein, San Marino, Monaco, Andorra and the Vatican City. Jorri Duursma makes a thorough analysis of the true origins, meaning and faults of the modern right of self-determination, asking fundamental questions: What constitutes a people with a right to self-determination? How small a people has this right? Who are allowed to secede? What is a state according to international law? Jorri Duursma's book provides an up-to-date and informed account of these important issues which also draws on recent experiences in Eastern Europe and Yugoslavia. It is the first book to provide a thorough international legal account of the European micro-states, and develops a novel approach to the problems of fragmentation.
