Designed to succeed previous books on the Maastricht and Amsterdam treaties, this work includes contributions from EU lawyers assessing the Nice Treaty and the Post-Nice process, which is rapidly developing in the lead-up to the next Intergovernmental Conference. The book's central theme is the discussion of a European Constitution and European Constitutionalism. The constitutional balance after institutional reform, the Luxembourg courts after Nice, the future of the three pillar treaty structure and the Human Rights charter are the other main topics.
