The present book invites the reader to rethink some questions raised in EU external relations law in the light of recent developments in the case law of the Court of Justice, from the perspective of the constitutional foundations of the Union. The various chapters invite the reader to take a look at the balance between the specific legal regime for EU external action and the constitutional fundamentals of the EU legal order such as: the principles of conferral, loyalty, and institutional balance, as well as the rule of law, democracy, and fundamental rights protection. The accommodation between specificity and fundamental principles is, thus, a transversal constitutional issue.

This edited collection appraises the role, self-perception, reasoning and impact of the European Court of Justice on the development of European Union (EU) external relations law. Against the background of the recent recasting of the EU Treaties by the Treaty of Lisbon and at a time when questions arise over the character of the Court's judicial reasoning and the effect of international legal obligations in its case law, it discusses the contribution of the Court to the formation of the EU as an international actor and the development of EU external relations law, and the constitutional challenges the Court faces in this context. To what extent does the position of the Court contribute to a specific conception of the EU? How does the EU's constitutional order, as interpreted by the Court, shape its external relations? The Court still has only limited jurisdiction over the EU's Common Foreign and Security Policy: why has this decision been taken, and what are its implications? And what is the Court's own view of the relationship between court(s) and foreign policy, and of its own relationship with other international courts? The contributions to this volume show that the Court's influence over EU external relations derives first from its ability to shape and define the external competence of the EU and resulting constraints on the Member States, and second from its insistence on the autonomy of the EU legal order and its role as 'gatekeeper' to the entry and effect of international law into the EU system. It has not - in the external domain - overtly exerted influence through shaping substantive policy, as it has, for example, in relation to the internal market. Nevertheless the rather 'legalised' nature of EU external relations and the significance of the EU's international legal commitments mean that the role of the Court of Justice is more central than that of a national court with respect to the foreign policy of a nation state. And of course its decisions can nonetheless be highly political.

The EU has established itself as a significant international legal actor. This volume brings together the key primary legal materials relating to the foreign relations powers of the EU and its practices, with editorial commentary. It is an ideal resource for students, scholars, and practitioners in the field.

This volume examines the legal and constitutional foundations of the EU's external relations. It focuses on the EU's external powers and objectives, on the instruments, principles and actors of external policies, and on the legal effects of international agreements and international law.

The Common Foreign and Security Policy (CFSP) of the European Union is a highly exceptional component of the EU legal order. This constitutionalised foreign policy regime, with legal, diplomatic, and political DNA woven throughout its fabric, is a distinct sub-system of law on the outermost sphere of European supranationalism. When contrasted against other Union policies, it is immediately clear that EU foreign policy has a special decision-making mechanism, making it highly exceptional. In the now depillarised framework of the EU treaties, issues of institutional division arise from the legacy of the former pillar system. This is due to the reality that of prime concern in EU external relations is the question of 'who decides?' By engaging a number of legal themes that cut across foreign affairs exceptionalism, executive prerogatives, parliamentary accountability, judicial review, and the constitutionalisation of European integration, the book lays bare how EU foreign affairs have become highly legalised, leading to ever-greater coherence in how Europe exerts itself on the global stage. In this first monograph dedicated exclusively to the law of the EU's Common Foreign and Security Policy in modern times, the author argues that the legal framework for EU foreign affairs must adapt in a changing world so as to ensure the EU treaties can cater for a more assertive Europe in the wider world.

The first edition of this seminal textbook made a significant impact on the teaching of EU external relations law. This new edition retains the hallmarks of that success, while providing a fully revised and updated account of this burgeoning field. It offers a dual perspective, looking at questions from both the EU constitutional law perspective (the principles underpinning EU external action, the EU's powers, and the role of the Court of Justice of the EU); and the international law perspective (the effect of international law in the EU legal order and the position of the EU in international organisations such as the WTO). A number of key substantive policy areas are explored, including trade, security and defence, police and judicial cooperation, the environment, human rights, and development cooperation. Taking a 'text, cases and materials' approach, it allows students to gain a thorough understanding of milestones in the evolution of EU law in this area, their judicial interpretation and scholarly appraisal. Linking these pieces together through the authors' commentary and analysis ensures that students are given the necessary guidance to properly position and digest these materials. Lastly, each chapter concludes with a section entitled 'The Big Picture of EU External Relations Law', which weaves together the diverse and complex materials into a coherent whole and stimulates critical discussion of the topics covered.

A collection of essays that surveys the development and structure of the European Union's constitutional regime for foreign affairs.

This book originates from the proceedings of the 10th anniversary conference of the Centre for the Law of EU External Relations (CLEER) in which renowned experts in the field took stock of recent evolutions in the law and practice of the EU’s external relations. In particular, the book addresses the question of how the evolving legal and political framework affects the nature of EU external relations law. The contributions discuss the actions (and reactions) of the EU through external action instruments in a number of substantive areas such as migration, trade, neighbouring policies, security and defence. By shedding light on the most significant developments of the past decade this edited volume attests to the ever-evolving nature of the field of EU External Relations Law. Thus, this book is essential reading for academics, practitioners and policy makers at the EU level interested in the field of EU External Relations Law. Dr. W.Th.

Expanding European Union activity on the international scene has led to development of the legal concepts, principles and rules that govern it. External relations law and practice have also been affected by events within the EU. This volume takes stock of the recent developments in the external relations law and practice of the EC/EU and investigates the increasing interaction between these different fields of Union competence. The first part of this book addresses issues that are broadly constitutional or institutional in character. The second part deals with various aspects of substantive external relations considered in a geographical or geopolitical perspective. The third part selects two specific substantive law areas - intellectual property law and environment law - as examples that illustrate the specific relationship between domestic policy and external relations.

This book reappraises the constitutional fundamentals of EU foreign relations law. The essays in the book examine and reassess the basic principles of EU foreign relations law that have emerged over 50 years of incremental Treaty-based and judicial development and explore the particular character of the EU's "external constitution". They have been written against a background of change and debate: the deliberation over the character of the appropriate constitutional framework which has surrounded the drafting of the Constitutional and Reform Treaties, the increasingly cross-pillar nature of much EU external action, and renewed interest in the accountability of foreign relations policy and practice to democratic and judicial review within and without the EU. This collection will be of interest not only to EU foreign relations law specialists but also to those concerned with broader constitutional issues within EU law. In exploring the legal context in which the EU seeks to develop an international identity, and to structure and execute policies at the international level, the collection will also interest those working in international relations.
