09-11-2023
The Treaty of Nice prepared the European Union only partially for the important enlargements to the east and south on 1 May 2004 and 1 January 2007. Therefore, following up on the questions raised in the Laeken Declaration, the European Convention made an effort to produce a new legal basis for the Union in the form of the Treaty establishing a Constitution for Europe. Following ‘no’ votes in referendums in two Member States, that treaty was not ratified.
