With a foreword by Atzo Nicolai, Minister for European Affairs of the Kingdom of the Netherlands On 29 October 2004, the Treaty Establishing a Constitution for Europe was signed by the leaders of the 25 Member States of the European Union. This event marked the end of the discussion rounds to amend the treaties on which the European Union is founded. Yet, the debate on the Constitution was far from over when on 29 May and 1 June 2005 the French and the Dutch voters rejected the Treaty. Politicians and lawyers are now confronted with the question of how to proceed and how to go forward. In October 2004, the T.M.C. Asser Institute in The Hague, The Netherlands, organized the 34th Session of its Asser Institute Colloquium on European Law, which was entitled 'The EU Constitution: The best way forward?'. During the Conference some 50 experts from the 25 Member States, from candidate, potential candidate and neighbouring countries, as well as from the US and Russia focused on key topics like: the process and impact of EU constitution-making, the democratic life of the EU, improving the efficiency and quality of legislation in the EU, the expansion of executive, judicial and legislative powers, and the access to justice. In anticipation of the developments after the signing of the Treaty, three eminent speakers - Prof. Joseph Weiler (New York University), Professor Bruno de Witte (European Institute in Florence) and Professor Jo Shaw (University of Manchester), elaborated on many answers in case of a ratification crisis. This book contains the proceedings of the three-day Conference and includes, next to the papers of the speakers and commentators, reports of the discussions on each topic and the texts of two keynote speeches. A keyword Index and a List of Articles (of the Treaty Establishing a Constitution for Europe, the Treaty on European Union and the Treaty Establishing the European Community) greatly enhance the accessibility of the rich materials. The book will be of great help and interest to political leaders, members of parliament, international lawyers and European citizens in formulating answers to the questions that have risen after the rejection of the Treaty by the French and Dutch voters and give powerful impulses to the continuing debate and efforts to arrive at a generally accepted Constitution for Europe.
