This textbook provides a thorough and accessible introduction to the basic principles of United Kingdom Constitutional and Administrative Law, including Human Rights law. By taking the reader through the key constitutional structures - including the notion of the UK constitution as developing "organically" and as a result of historical development and practical compromises - the authors are able to guide the reader step-by-step to a clearer understanding of UK Constitutional and Administrative Law. This book is therefore an essential starting point for more advanced law students and a valuable source of legal context for political science students alike. Both authoritative and accessible, it enables the reader to appreciate the complexity and beauty of this most fundamental part of our legal system.
