The aims of this edition remain the same as those of previous editions: namely, to explain and discuss critically the general principles of the constitutional law and administrative law of the UK and to identify their historical and political foundations. This edition has been recast and substantially rewritten and expanded in order to take account of major changes in the law, notably the burgeoning case law generated by the Human Rights Act 1998, and to consider recent scholarship and political developments. I have tried to make the book clearer and easier to use both as an introductory text for law degree students and as a self-contained text for.
