This title provides a comprehensive overview of European migration law. More than three dozen directives and regulations are discussed throughout this volume, together with numerous court judgments, international treaties, reform proposals, and factual developments. This careful inspection of EU legislation and cases is accompanied by analyses of domestic and international developments, as well as contextual factors influencing the real world of migratory movements. Across eighteen chapters, Daniel Thym discusses core features of visas and border controls, asylum and legal migration, integration and return, association agreements, and international cooperation. The work consists of two parts. In the first part, Thym provides an analysis of the general framework behind the EU rules on migration and the changing positions of the supranational institutions. Central to this part is a discussion on the significance of human rights and the case law of the Court of Justice. Several chapters identify general features guiding the interpretation and the administrative implementation of the common rulebook. In the second part of the book, Thym explores the policy design and the substance approached through a thematic, rather than a chronological, lens. These chapters provide a reliable inventory of the policy design, the legislation and judgments on all areas of European migration law.
