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.

Based on author's thesis (doctoral - Det Juridiske Fakultet, K2benhavns Universitet, 2015), issued under title: Regime interaction in the regulation of greenhouse gas emissions from international aviation and maritime transport.

Leading scholars advance the discussion of international law's fragmentation in new and provocative ways.

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.

It has never been more important to understand how international law enables and constrains international politics. By drawing together the legal theory of Lon Fuller and the insights of constructivist international relations scholars, this book articulates a pragmatic view of how international obligation is created and maintained. First, legal norms can only arise in the context of social norms based on shared understandings. Second, internal features of law, or 'criteria of legality', are crucial to law's ability to promote adherence, to inspire 'fidelity'. Third, legal norms are built, maintained or destroyed through a continuing practice of legality. Through case studies of the climate change regime, the anti-torture norm, and the prohibition on the use of force, it is shown that these three elements produce a distinctive legal legitimacy and a sense of commitment among those to whom law is addressed.

Today international law is everywhere. Wars are fought and opposed in its name. It is invoked to claim rights and to challenge them, to indict or support political leaders, to distribute resources and to expand or limit the powers of domestic and international institutions. International law is part of the way political (and economic) power is used, critiqued, and sometimes limited. Despite its claim for neutrality and impartiality, it is implicit in what is just, as well as what is unjust in the world. To understand its operation requires shedding its ideological spell and examining it with a cold eye. Who are its winners, and who are its losers? How - if at all - can it be used to make a better or a less unjust world? In this collection of essays Professor Martti Koskenniemi, a well-known practitioner and a leading theorist and historian of international law, examines the recent debates on humanitarian intervention, collective security, protection of human rights and the 'fight against impunity' and reflects on the use of the professional techniques of international law to intervene politically. The essays both illustrate and expand his influential theory of the role of international law in international politics. The book is prefaced with an introduction by Professor Emmanuelle Jouannet (Sorbonne Law School), which locates the texts in the overall thought and work of Martti Koskenniemi.

This collection of essays focusses on the following concepts: sovereignty (the unique, intangible and yet essential characteristic of states), statehood (what it means to be a state, and the process of acquiring or losing statehood) and state responsibility (the legal component of what being a state entails). The unifying theme is that they have always been and will in the future continue to form a crucial part of the foundations of public international law. While many publications focus on new actors in international law such as international organisations, individuals, companies, NGOs and even humanity as a whole, this book offers a timely, thought-provoking and innovative reappraisal of the core actors on the international stage: states. It includes reflections on the interactions between states and non-state actors and on how increasing participation by and recognition of the latter within international law has impacted upon the role and attributes of statehood.
