The Constitution for the European Union and the Treaty of Lisbon

Between February 2002 and July 2003, the Convention on the Future of Europe took place with the intent of developing a draft constitution for the EU. The Draft Constitution was completed and presented to the President of the EU by the President of the Convention on July 18, 2003. The final version of the proposed constitution, called the Treaty Establishing a Constitution for Europe, was signed by the heads of state on October 29, 2004. It was submitted to the member states for ratification. Although it has been ratified by fifteen countries, the Treaty was defeated in France and the Netherlands in June 2005. Following those defeats, the European Council decided to review the constitution and the ratification process in early 2006. In their June 2006 meeting, the European Council extended the period of review and reflection for another two years.

After this period of review, the Treaty of Lisbon was signed on December 13, 2007 and entered into force on December 1, 2009. The Treaty of Lisbon replaces the Constitution.
