Nearly a quarter century after the September 11, 2001 attacks, the U.S.-led war on terror remains a defining force shaping international law, human rights, and global security. While major combat operations in Afghanistan and Iraq have formally ended, the long-anticipated shift from a war paradigm to a law enforcement approach has yet to materialize. Instead, U.S. and allied counterterrorism activities persist worldwide, raising urgent questions about the role of law in enabling and sustaining armed conflict.

Perpetual War and International Law brings together leading experts to confront the enduring legacies of the post-9/11 era and explore viable alternatives to the use of force. The volume traces how legal and policy frameworks have served to legitimize military action, eroding the boundary between war and peace. Contributors challenge prevailing interpretations of international law in an age of endless war and unconventional threats.

Drawing on insights from law, ethics, and security studies, the volume critically examines how legal and normative precedents established during the war on terror continue to shape contemporary conflicts. It offers bold pathways for shifting from a global order rooted in force to one grounded in restraint and the rule of law. Perpetual War and International Law is a vital intervention, inviting readers to reimagine how international law can constrain violence in an increasingly conflict-ridden world.

Under the United Nations Convention on the Law of the Sea (UNCLOS), a State's maritime zones and the rights they confer are tied to its land territory. As climate change accelerates coastal erosion and inundation, traditional assumptions suggest these entitlements could shrink or disappear, with profound implications for access to marine resources. Sea-Level Rise and the Legal Stability of Maritime Zones explores the development of a new legal perspective that supports the preservation of maritime zones despite rising sea levels.

This book advances a contemporary interpretation of UNCLOS, drawing on a broad spectrum of state practice as reflected in international declarations and domestic legislation. Through systematic analysis of this evidence within the framework of treaty interpretation, Frances Anggadi consolidates the doctrinal basis for the view that the preservation of maritime zones may be achieved through interpreting existing provisions of UNCLOS, rather than requiring a treaty amendment.

As the first comprehensive work to conceptualize this emerging perspective, it offers a clear and principled framework for safeguarding maritime zones, demonstrating how international law can evolve to address global environmental challenges.

     

Established in the wake of the First World War, the League of Nations fundamentally transformed international politics, global governance and multilateral cooperation in a multitude of fields from the economy, labour and social affairs to colonial, minority and security questions. This Handbook analyses the central role of law in the construction of a new international order under the League of Nations. Drawing from innovative research of recent years that analyses the League of Nations through the prism of ultimate success and failure, it offers twenty-one rich chapters that showcase an interdisciplinary, contextual and archive-based approach with brand new and unexplored case studies that address key topics of the legal history of the League, the International Labour Organization and the Permanent Court of International Justice. Finally, it offers a new historical synthesis of how to understand the role of international law in international organizations during the interwar period.

This book explores the seminal importance of the first UN Conference on the Human Environment in Stockholm 1972 – the Stockholm Conference – for the development of international environmental law. By bringing together world leading experts from academia and legal practice, the book charts the development of international environmental law in the 50 years since 1972 in the areas of nature and biodiversity, chemicals and waste, oceans and water, and atmosphere and climate, and with respect to structures and institutions, consumption and production, and human rights and participatory rights in environmental matters. It analyses how the ideas and concepts of the Stockholm Conference have influenced this development and explores the novel ideas that have emerged since then. It describes the approaches of the developed and developing countries in this process and the relationship between international environmental law and other areas of law, such as the law of the sea and international economic law.

     

Why do some international courts wield broad authority while others face pushback or fade into irrelevance? This book provides novel theoretical and empirical insights into this question. It offers a fresh, interdisciplinary perspective on the authority of international courts, drawing from law, political science and behavioural research.

It develops, in Part I, a theoretical model and analytical framework for assessing these questions. The model explains how authority relationships between courts and their audiences – such as states, NGOs, individual applicants, and domestic courts – are formed, maintained, or contested. In Part II, the book applies this analytical framework to in-depth case studies of two selected international courts: the European Court of Human Rights and the Court of Justice of the Economic Community of West African States. These studies not only provide deeper insights into the authority of these courts but also demonstrate how the analytical framework can be applied to other international courts to generate an enhanced understanding of international court authority.

The book sheds new light on why some courts enjoy enduring authority and others face pushback, offering powerful tools for understanding the behaviour of international courts and their audiences.

     

Regional courts increasingly shape domestic law and policy, raising pressing questions about their democratic legitimacy. Balancing International Judicial Independence offers a groundbreaking framework for reconciling judicial independence with legitimate checks on judicial power. While independence is essential for courts to function, unchecked authority can be equally problematic. This book advances a nuanced approach that incorporates accountability and oversight without compromising independence.

Part One introduces a conceptual framework for international judicial independence, tailored to the unique institutional and political contexts of regional courts and avoiding the uncritical application of domestic models. It draws on comparative analysis of courts in Europe and the Americas, including the European Court of Human Rights, the European Court of Justice, the Inter-American Court of Human Rights, and the Andean Tribunal of Justice.

Part Two explores the normative foundations for constraining judicial power, examining legal accountability mechanisms and adapting the principle of checks and balances to the international sphere. Political constraints are reconceptualized as forms of institutional interdependence within a refined checks and balances framework.

Part Three tackles the implications of using checks and balances as a normative guiding principle and critically analyses national and regional institutional sources of constraint on selected courts, as well as specific mechanisms like judicial selection, political override, and non-compliance.

Filling a critical gap in the literature, this book provides a principled framework for scholars, practitioners, and policymakers to assess existing arrangements and guide institutional design in international adjudication.
