With a view to recent developments in both the EU and the global legal order, International Law as Law of the European Union explores how, and to what extent, international law still forms part of, and plays a role in, the current legal order of the European Union.

International Law and the European Union addresses the public international law issues that arise from the European Union's international action.

The book offers a systematic discussion of the facets of the relationship between the European Union and customary international law.

The Law of the European Union is a complete reference work on all aspects of the law of the European Union, including the institutional framework, the Internal Market, Economic and Monetary Union and external policy and action. Completely revised and updated, with many newly written chapters, this fifth edition of the most thorough resource in its field provides the most comprehensive and systematic account available of the law of the European Union (EU). Written by a new team of experts in their respective areas of European law, its coverage incorporates and embraces many current, controversial, and emerging issues and provides detailed attention to historical development and legislative history of EU law. Topics that are constantly debated in European legal analysis and practice are touched on in ways that are both fundamental and enlightening, including the following: .powers and functions of the EU law institutions and relationship among them; .the principles of equality, loyalty, subsidiarity, and proportionality; .free movement of persons, goods, services, and capital; .mechanisms of constitutional change – treaty revisions, accession treaties, withdrawal agreements; .budgetary principles and procedures; .State aid rules; .effect of Union law in national legal systems; .coexistence of EU, European Convention of Human Rights (ECHR), and national fundamental rights law; .migration and asylum law; .liability of Member States for damage suffered by individuals; .competition law – cartels, abuse of dominant position, merger control; .social policy, equal pay, and equal treatment; .environmental policy, consumer protection, public health, cultural policy, education, and tourism; .nature of EU citizenship, its acquisition, and loss; and .law and policy of the EU’s external relations. The fifth edition embraces many new, ongoing, and emerging European legal issues. As in the previous editions, the presentation is notable for its attention to how the law relates to economic and political realities and how the various policy areas interact with each other and with the institutional framework. The many practitioners and scholars who have relied on the predecessors of this definitive work for years will welcome this extensively revised and updated edition. Those coming to the field for the first time will instantly recognize that they are in the presence of a masterwork that can always be turned to with profit and that helps in understanding the rationale underlying any EU law provision or principle.

The debate about the relationship between international and community law usually centres on the question of which of these two 'belongs' to the other, and how 'special' community legal order is in relation to international law. In this volume, a distinguished group of Finnish and British academics and practitioners break new ground by, instead of becoming mired in these questions, clearly examining the international law aspects of the activities of the Community and the Union. In doing so, they have elucidated points of connection and possible points of conflict. The result is a thought-provoking collection of essays which examines community law through the conceptual grid of international law, and thus enriches our understanding of the workings of both.

Jan Klabbers examines how membership of the European Union affect treaties concluded between the member and non-member states.

The European Union plays a significant role in international affairs. International Law and the European Union examines the impact this has had on public international law by integrating perspectives from both EU law and international law. Its analysis focuses on fields of public international law where the EU has had an influence, including customary international law, the law of treaties, international organizations, international dispute settlement, and international responsibility. International Law and the European Union shows how the EU has had a subtle but significant impact on the development of international law and how the international legal order has developed and adjusted to accommodate the EU as a distinct legal actor. In doing so, it contributes to our understanding of how international law addresses legal subjects other than States.
