This classic casebook reflects the many institutional and substantive changes brought about by the Treaty of Lisbon of December 2009. Divided into seven parts, this casebook allows teachers the flexibility to tailor their courses to their own needs. Parts I and II, respectively, treat the legal/institutional framework of the EU and the enforcement of EU law in the Member States. Part III covers all aspects of the Internal Market and its free movement principles. Part IV comprehensively covers European competition policy, while Part V fully treats the EU’s external, including trade, relations and Part VI treats issues surrounding the Euro. Finally, Part VII presents a sampling of EU policy areas e.g., social policy, environmental and consumer protection.
