The fifth edition of Hilaire Barnett's "Constitutional Administrative Law" is published at a time of continuing constitutional development and reform. Membership of the European Union has expanded from fifteen to twenty-five states. House of Lords reform is ongoing, now with plans to abolish the office of Lord Chancellor, establish a new Supreme Court and introduce a new system of judicial appointments. Other significant areas of reform discussed in the book include the police and police powers, asylum and immigration law. "Constitutional Administrative Law" provides a clear exposition of the major features of the UK's constitution and a comprehensive summary of recent developments. The book has been consciously designed to meet the needs of students undertaking a constitutional and administrative law course, whether full or part time, and provides comprehensive coverage of the syllabus drawn from a wide range of sources.
