The European Union enjoys the competence to make laws in a wealth of areas, from environmental protection to agricultural policy. This competence is the result of many years of building and promoting European-level co-operation and integration. European Law Essentials explores the legal development of the EU. It introduces the background history of the union, then moves on to look at membership, institutions, community law, supremacy, direct effect, state liability, preliminary rulings and judicial review, and finishes by looking to the future of law in the EU. End-of-chapter summaries flag up the essential facts and essential cases, and the book includes tables of cases, statues and European legislation.
