For all those embarking on the study of constitutional and administrative law, this is the standard textbook. Now in its eighth edition, this highly-respected work provides comprehensive coverage, ensuring a solid grounding in the subject, with no prior knowledge assumed. With substantial developments in recent years in this area of law, including fundamental changes affecting the United Kingdom's place within Europe as a member of and contributor to its institutions, Yardley has been largely restructured and updated. In particular, there is a new chapter on Europe and the section on administrative law has been considerably expanded in accordance with the latest compulsory core requirements. This now gives a more balanced reflection of the function of administrative law as a practical expression of constitutional precepts. Other fresh material deals with changes in the civil service, alterations made by the courts to the rules of statutory interpretation, negotiations concerning Northern Ireland, and the significant amount of new legislation which has appeared since the last edition in 1990.
