This volume provides an introduction to the United Kingdom's constitution that recognises and embraces its historical, social, political, and legal dimensions. It critically examines the radical changes to the UK constitution that have occurred over the last thirty years, paying particular attention to the revival of the constituent territories of the UK - Wales, Scotland, Northern Ireland, and England - and to the increasing role played by the judges in constitutional disputes. The UK constitution is presented as being shaped by a set of constitutional principles, including state sovereignty, separation of powers, democracy, subsidiarity, and the rule of law, principles which set the overall structure of the constitution and inform statutes and the decisions of judges. Adopting a principled approach to the UK constitution allows us to see both the clarity of the constitution's structure and also helps explain its complexities.

In Lord Sumption and the Limits of the Law, leading public law scholars reflect on the nature and limits of the judicial role and its implications for human rights protection and democracy. The starting point for this reflection is Lord Sumption's lecture, 'The Limits of the Law', which grounds a wide-ranging discussion of questions including the scope and legitimacy of judicial law-making, the interpretation of the European Convention on Human Rights, and the continuing significance and legitimacy, or otherwise, of the European Court of Human Rights. Lord Sumption ends the volume with a substantial commentary on the responses to his lecture.

In this follow-up volume to the critically acclaimed The Constitutional State, N. W. Barber explores how the principles of constitutionalism structure and influence successful states. Constitutionalism is not exclusively a mechanism to limit state powers. An attractive and satisfying account of constitutionalism, and, by derivation, of the state, can only be reached if the principles of constitutionalism are seen as interlocking parts of a broader doctrine. This holistic study of the relationship between the constitutional state and its central principles - sovereignty; the separation of powers; the rule of law; subsidiarity; democracy; and civil society - casts light on long-standing debates over the meaning and implications of constitutionalism. The book provides a concise introduction to constitutionalism and a detailed account of the nature and implications of each of the principles in question. It concludes with an examination of the importance of constitutional principles to the work of judges, legislators, and others involved in the operation and creation of the constitution. The book is essential reading for those seeking a definitive account of constitutionalism and its benefits.

The Draft European Constitution was arguably both an attempt to constitutionalise the Union, re-framing that project in the language of the state, and an attempt to stretch the boundaries of constitutionalism itself, re-imagining that concept to accommodate the sui generis European Union. The (partial) failure of this project is the subject of this collection of essays. The collection brings together leading EU constitutional scholars to consider, with the benefit of hindsight, the purportedly constitutional character of the proposed Constitutional Treaty, the reasons for its rejection by voters in France and the Netherlands, the ongoing implications of this episode for the European project, and the lessons it teaches us about what constitutionalism really means.
