By voting "no" in their referendums, the people of France and the Netherlands rejected the Constitution. Does that mean that the Constitution project has now been abandoned?

Before it can enter into force, the Constitution for Europe must be ratified by all the Member States of the European Union. However, the two "no" votes do not mean an end to the ratification process, which is continuing according to plan. The present situation is as follows: 15 Member States have already ratified the Constitution for Europe: Austria, Belgium, Cyprus, Estonia, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Luxembourg, Malta, Slovakia, Slovenia and Spain. The people of France and the Netherlands rejected the text of the Constitution on 29 May and 1 June respectively.
