This book provides a comprehensive practitioner guide to the EU law of State aid, covering all relevant legislation, case law, and the dominant themes shaping EU State aid policy. It discusses the concept of State aid and its development in the European Union, as well as practical aspects such as procedures for notification to the European Commission, and enforcement in the European Court and national courts. It offers extensive coverage of specific sectors, including transport and shipbuilding, media and communications, energy and environmental protection, culture and heritage, and agriculture. The third edition is fully updated to cover the extensive legislative changes in this area, including the new General Block Exemption Regulation and De Minimis Regulation, horizontal aid guidelines, and sectoral guidelines for aviation, cinemas, agriculture, and fisheries; as well as State aid cases in the national courts, particularly the UK, and recent European Court jurisprudence. Accessible to competition lawyers and non-specialists, the book's clarity and concision make it an invaluable reference to this area of law.
