Extracts have been chosen from a wide range of historical and contemporary cases to illustrate the reasoning processes of the courts and to show how legal principles are developed. Cases & Materials on Constitutional and Administrative Law is an invaluable resource. Extracts from the leading cases are combined with legal, political, and philosophical materials and linked together with explanatory text, alongside extensive notes and questions for discussion. The book takes a critical look at the main doctrines of constitutional law as well as the principles of administrative law, examining the operation of the constitution in relation to Parliament, the Executive, and the citizen. Incisive commentary throughout the text provides a range of views on challenging issues. The twelfth edition has been fully revised and updated to reflect the latest developments in legislation, case law, and politics, including the referendum decision to leave the European Union; continuing change to the devolution settlement; major Supreme Court decisions in HS2, Evans, Miller and Pham; and discussion of aspects of reforms of judicial review and tribunal appeal processes as well as proposed reform of ombudsmen. This text continues to provide instant access to an unrivalled collection of up-to-date judgments, statutory provisions, official publications, and other policy materials.
