First or second year LLB courses in constitutional and administrative law or public law in law departments. One-year full-time or two-year part-time CPE (common professional examination) or Diploma courses in law departments. This book is the leading undergraduate textbook on constitutional and administrative law. It is logically structured and accessibly written for students. It is also completely comprehensive and authoritative on all matters relating to public law. Constitutional law is examined in the context of political science and economic change. The new edition takes on the tremendous task of describing and analysing the wide variety of changes in the UK's system of government and public law since 1998, notably the wide-ranging reform of the constitution undertaken by the Labour Government and the incorporation into English law of the European Convention on Human Rights
