On October 29, 2004, the Heads of State or Government and Ministers of Foreign Affairs of the 25 member states of the European Union and the heads of Institutions of the European Union gathered together at the Campidogli in the Sala Orazi and Curiazi, the same room where the original Treaties of Rome had been signed in 1957. The European political leaders came to Rome to sign the Treaty and the Final Act establishing a Constitution for Europe. The aims of this article is to shed more lights on the process from the Convention through the IGC-2003/2004 to the ratification procedures and analyse the politics among the member states of the European Union and European institutions. The European Union had muddled through and managed to adopt the Treaty establishing a Constitution for Europe. But, again this time, it is still not “Finality”. The European Union has not yet reached its final destination. As Antje Wiener predicted that “it is not the end of the story but a mere stage in the process of constitutional change in the EU”. The member states are now in process of its ratification through parliamentary decisions and/or referendums. The forecast seems to be not so bright and not so easy especially in some of the member states holding referendums. Thus, it is in the hands of citizens to decide the fate of the Treaty establishing a Constitution for Europe.
