International courts use two key methodologies to determine the degree of deference granted to states in their implementation of international obligations: the standard of review and margin of appreciation. This book investigates how these doctrines are applied in international courts, analysing where their approaches converge and diverge.

This book provides a comprehensive explanation of what the right to a fair trial means in practice under international law. Focus on factual scenarios that practitioners may, it brings together sources and cases that define the right to a fair trial in criminal proceedings.

The margin of appreciation is a judicial doctrine whereby international courts allow states to have a measure of diversity in their interpretation of human rights treaty obligations. The doctrine is at the heart of some of the most important international human rights decisions. Does it undermine the universality of human rights? How should judges decide whether to give this margin of appreciation to states? How can lawyers make best use of arguments for or against the margin of appreciation? This book answers these questions, and broadens the discussion on the margin of appreciation by including material beyond the ECHR system. It provides a comprehensive justification of the doctrine, and ALLFSCA14I the key cases affecting the doctrine in practice. Part One provides a systematic defence of the margin of appreciation doctrine in international human rights law. Drawing on the philosophy of practical reasoning the book argues that the margin of appreciation is a doctrine of judicial deference and is a common and appropriate feature of adjudication. The book argues that the margin of appreciation doctrine prevents courts from imposing unhelpful uniformity, whilst allowing decisions to be consistent with the universality of human rights. Part Two considers the key case law of the European Court of Human Rights, the Inter-American Court of Human Rights, and the UN Human Rights Committee, documenting the margin of appreciation in practice. The analysis uniquely takes a broad look at the factors affecting the margin of appreciation. Part Three explores how the margin of appreciation operates in the judicial decision-making process, reconceptualising the proportionality assessment and explaining how the nature of the right and the type of case affect the courts' reasoning.

The book seeks to investigate problems relating to the increased interaction between national and international courts, which have resulted in the litigation of the same legal issues before national and international judicial bodies: What is the proper order of the proceedings? Should national and international proceedings take place concurrently? What effect, if any, should be given to decisions of national court in proceedings before an international court and vice versa? In particular, the book advocates the use of judicial comity as a method for mitigating jurisdictional tensions between national and international courts.

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.
