Far from displaying a uniform pattern, European integration varies significantly across policy areas and individual countries. Why do some member states choose to opt out of specific EU policies? Why are some policies deeply integrated whereas others remain intergovernmental? In this updated second edition, the authors introduce the most important theoretical approaches to European integration and apply these to the trajectories of key EU policy areas. Arguing that no single theory offers a completely convincing explanation of integration and differentiation in the EU, this thought-provoking book provides a new synthesis of integration theory and an original way of thinking about what the EU is and how it works.

The Routledge Handbook of Differentiation in the European Union offers an essential collection of groundbreaking chapters reflecting on the causes and consequences of this complex phenomenon. With contributions from key experts in this subfield of European Studies, it will become a key volume used for those interested in learning the nuts and bolts of differentiation as a mechanism of (dis)integration in the European Union, especially in the light of Brexit. Organised around five key themes, it offers an authoritative "encyclopaedia" of differentiation and addresses questions such as: How can one define differentiation in the European Union in the light of the most recent events? Does differentiation create more challenges or opportunities for the European Union? Is Europe moving away from an "ever closer Union" and heading towards an "ever more differentiated Union", especially as leading political figures across Europe favour the use of differentiation to reconcile divergences between member states? This handbook is essential reading and an authoritative reference for scholars, students, researchers and practitioners involved in, and actively concerned about, research in the study of European integration. As European differentiation is multifaceted and involves a wide range of actors and policies, it will be of further interest to those working on countries and/or in policy areas where differentiation is an increasingly relevant feature.

The notion of Differentiated Integration is increasingly used in the literature on European integration. Often employed interchangeably with the notion of "flexible integration, diverging views on its nature have led to the emergence of various definitions and, to some extent, a semantic confusion. A lack of consensus characterizes the academic literature; some authors even avoid putting an explicit definition on the term. The main objective of this book is to seek answers for the following questions: How can one define Differentiated Integration in the European Union? Should Differentiated Integration be considered as a process, a concept, a system or a theory? Should it be seen as a temporary or a well-established phenomenon? How is this field of study likely to develop in the future? In order to do so, all chapters, written by leading experts in the field, offer a state-of-the-art analysis of the study of differentiated integration, from theoretical and practical perspectives. In addition, this book is not a collection of isolated papers: all chapters are interconnected and gravitate towards the aforementioned central questions, but approach these from different perspectives. This book was published as a special issue of the Journal of European Public Policy.

Against the backdrop of a more differentiated European Union, this book discusses the relationship between differentiation and domination in the EU in relation to how it has been transformed through the financial and refugee crises, the COVID-19 pandemic, the Russian invasion of Ukraine, and in general, a more volatile and less rule-bound global context. In doing so, it assesses to what extent these adaptations represent significant change, generating new problems and challenges, or on the other hand, providing an opportunity for new solutions or even signalling a new approach to governance that can mitigate problems associated with domination. Differentiation is discussed not only from a legal perspective, but with special attention to structural and institutional arrangements, which includes patterns of path dependence and built-in biases. This book will be of key interest to scholars and students of public sector crisis management, international organisations, and EU politics and studies.

This book offers the first comprehensive legal study dedicated to the understanding of the Danish EU opt-outs. The impact of these is significant, falling as they do within Union citizenship, the euro, defense cooperation and the Area of Freedom, Security and Justice. Through a re-examination of the opt-outs individually, collectively and temporally, the book sheds light on their legal design and their interplay between international law, EU law and national law. This pioneering book takes a legal-doctrinal approach, which provides readers with a solid understanding of the opt-outs. Academics, judges and European Union civil servants will find this invaluable.

While the discussions among Brexiters mainly focus on the referendum of 2016 or David Cameron’s “great miscalculation” and its repercussions, this book looks at the Brexit as a process that began decades earlier. It analyses EU-UK relations from a new perspective, taking into consideration the historical background, political aspects, and legal and economic matters. The book provides a holistic understanding of the Brexit, approaching the referendum and its outcomes as the culmination of a long process rather than an isolated political event crafted within the corridors of Westminster or Downing Street 10. Accordingly, it addresses a range of thematic issues, historical patterns of political and economic behavior both within and beyond the United Kingdom, and possible future effects on relations between the Union and one of its most important members.

The European Union affects the lives of Europeans in many and varied ways, yet, in spite of its reach, it often appears a constrained political system – struggling for internal consensus, reliant on the agreement of national governments, and hampered by the scepticism of electorates. These issues have become even more acute in the wake of the global economic and eurozone crises. This new text provides a concise and up-to-date introduction to the nature of the European Union, giving an account of its evolution and structure that makes sense of its current challenges. The text analyses the EU's institutional structure and decision-making procedures, and highlights the manifold conflicts as well as the sophisticated mechanisms for consensus-building among the core institutions. It explains the ways in which the EU differs from other forms of political order, and how this leads to political processes that are characterized by cooperation and conflict. In providing this context, the author invites readers to a critical assessment of the functioning of the European Union, and of the implications of this for its democratic legitimacy and future prospects.

The introduction by the Amsterdam Treaty of the flexibility clauses, authorising a majority of Member States to cooperate more closely in areas covered by the Treaties, has been received with mixed feelings. Flexibility is by no means a new phenomenon in the EU's development. It has been on the Community's agenda already since the 1970s. The Single European Act introduced several provisions allowing for flexible approaches to the single market, whilst the Maastricht Treaty launched a differentiated approach to the EMU and social policy. In addition to these forms of differentiation in primary Community law, for many years there has also been a number of quite important, though less visible, forms of differentiation in secondary Community law. This book aims to link both levels of differentiation and seeks to unveil the many faces of differentiation in EU law. It analyses whether, and to which extent, there is a shift in European integration from a system of unity and uniformity to one of flexibility and differentiation. A first series of contributions to the book analyse a number of exemplary policy fields (EMU, social policy, environment, free movement of persons, justice and home affairs) in order to identify their degree of differentiation. A second set of contributions examine various 'horizontal' institutional matters of cross-sectoral importance. These two main parts are framed by introductory articles on the development of flexibility and by contributions drawing on the constitutional limits to differentiation. The contributions are made by Dominik Hanf, José M. de Areilza, Jean-Victor Louis, Sean Van Raepenbusch, Ludwig Kramer, Georgia Papagianni, Grainne de Burca, Ellen Vos, Linda Senden, Sacha Prechal, Wouter Devroe, Deirdre Curtin, Bruno De Witte, Eddy De Smijter en Jan Wouters.

The European Union's history exhibits numerous episodes in which Member States have sought to re-enforce their national autonomy in the face of deepening integration. Efforts to re-gain autonomy, however, are often accompanied by legitimate concerns that autonomy will lead to dis-integration or will have wider destructive consequences. The EU thus faces a dilemma. Calls for autonomy cannot all be dismissed as mere populist rhetoric or national egoism but instead represent a legitimate questioning of the degree of uniformity that EU law and politics presently carry. At the same time, the fear that greater autonomy may carry dis-integrative effects is also legitimate -uniformity is not an accidental by-product of the EU's construction but intrinsically related to its policy goals. Giving too much room for autonomy might create an opportunity structure for the loss of collective goods, deficits in problem-solving, and perhaps even to self-destruction. The EU requires autonomy, but in doing so, it must also avoid collapse. Can it achieve it, and if so, how? Autonomy without Collapse is devoted to exploring innovative answers to this question. It draws together scholars in law and political science interested in exploring how to overcome the central dilemma of preserving sustainable yet real autonomy in the future European Union.

Turning Points: Challenges for Western Democracies in the 21st Century centers around the strikingly under-researched concept of turning points and its application in political science, including various theories, fields, and sub-disciplines. The chapters provide theoretical discussion and conceptual clarity by distinguishing a set of turning points at different analytical levels. Based on a wide range of case studies, the authors illustrate where, when and how different types of turning points occur (or not) against the backdrop of current challenges in and for Western democracies. The conceptual and empirical variety of the volume allows scholars and practitioners in policymaking to develop and apply their own frameworks when dealing with turning point dynamics.
