Domestic law has long been recognised as a source of international law, an inspiration for legal developments, or the benchmark against which a legal system is to be assessed. Academic commentary normally re-traces these well-trodden paths, leaving one with the impression that the interaction between domestic and international law is unworthy of further enquiry. However, a different - and surprisingly pervasive - nexus between the two spheres has been largely overlooked: the use of domestic law in the interpretation of international law. This book examines the practice of five international courts and tribunals to demonstrate that domestic law is invoked to interpret international law, often outside the framework of Articles 31 to 33 of the Vienna Convention on the Law of Treaties. It assesses the appropriateness of such recourse to domestic law as well as situating the practice within broader debates regarding interpretation and the interaction between domestic and international legal systems.

This pioneering study on environmental case-law examines how courts engage with science and reviews legitimate styles of judicial reasoning.

One of the most noted developments in international law over the past twenty years is the proliferation of international courts and tribunals. They decide who has the right to exploit natural resources, define the scope of human rights, delimit international boundaries and determine when the use of force is prohibited. As the number and influence of international courts grow, so too do challenges to their legitimacy. This volume provides new interdisciplinary insights into international courts' legitimacy: what drives and undermines the legitimacy of these bodies? How do drivers change depending on the court concerned? What is the link between legitimacy, democracy, effectiveness and justice? Top international experts analyse legitimacy for specific international courts, as well as the links between legitimacy and cross-cutting themes. Failure to understand and respond to legitimacy concerns can endanger both the courts and the law they interpret and apply.

The book explains when international courts should and when they should not intervene in domestic affairs. It is based on both empirical and theoretical inquires that circumscribe the cases when intervention of international courts is legitimate, likely to identify good legal solutions, and will lead to good outcomes.

Offers a new understanding of traditional rules on jurisdiction and admissibility of cases before international courts and tribunals.

The Oxford ILDC online database, an online collection of domestic court decisions which apply international law, has been providing scholars with insights for many years. This ILDC Casebook is the perfect companion, introducing key court decisions with brief introductory and connecting texts. An ideal text for practitioners, judged, government officials, as well as for students on international law courses, the ILDC Casebook explains the theories and doctrines underlying the use by domestic courts of international law, and illustrates the key importance of domestic courts in the development of international law.

This book examines an unexplored method of interpretation: the use of domestic law in the interpretation of international law.

A compelling new look at the role of today's international courts In 1989, when the Cold War ended, there were six permanent international courts. Today there are more than two dozen that have collectively issued over thirty-seven thousand binding legal rulings. The New Terrain of International Law charts the developments and trends in the creation and role of international courts, and explains how the delegation of authority to international judicial institutions influences global and domestic politics. The New Terrain of International Law presents an in-depth look at the scope and powers of international courts operating around the world. Focusing on dispute resolution, enforcement, administrative review, and constitutional review, Karen Alter argues that international courts alter politics by providing legal, symbolic, and leverage resources that shift the political balance in favor of domestic and international actors who prefer policies more consistent with international law objectives. International courts name violations of the law and perhaps specify remedies. Alter explains how this limited power--the power to speak the law--translates into political influence, and she considers eighteen case studies, showing how international courts change state behavior. The case studies, spanning issue areas and regions of the world, collectively elucidate the political factors that often intervene to limit whether or not international courts are invoked and whether international judges dare to demand significant changes in state practices.

International lawyers usually disregard the vital functions that general principles of law may play in the decisions of international courts and tribunals. As far as international criminal law is concerned, general principles of law may be crucial to the outcome of an international trial, inter alia because the conviction of an accused in respect of a particular charge may depend on the existence of a given defence under this source. This volume examines the role that general principles of law have played in the decisions of international criminal courts and tribunals. In particular, it analyses their alleged ‘subsidiary’ nature, their process of determination, and their transposition from national legal systems into international law. It concludes that general principles of law have played a significant role in the decisions of international criminal courts and tribunals, not only by filling legal gaps, but also by being a fundamental means for the interpretation of legal rules and the enhancement of legal reasoning.
