The need to balance power between the Member States and the Union and between public power and the market has created powerful constitutional dilemmas for the European Union. Adopting an inter-disciplinary approach and drawing upon the jurisprudence developed around Article 30, this new book offers both a descriptive and a normative analysis of the European Economic Constitution and discusses the role of the European Court of Justice in its development and in the review of State and Community legislation. The book is particularly relevant in view of the present debates on the European Constitution and the reform of the regulatory State.
