Please note that this is not the newest version of the Lisbon Treaty.
An amended version will be published in early 2010.

Changes to the European Union's Treaties have always come about through amendments to previous Treaties: this was true of the Single European Act, as well as the Treaties of Maastricht, Amsterdam and Nice. Through the Treaty of Lisbon, signed on 13 December 2007, the Union's two main Treaties (Maastricht and Rome) will be renamed the 'Treaty on European Union' and the 'Treaty on the Functioning of the European Union'.

This issue of the Official Journal of the European Union contains the consolidated text of those two core Treaties, integrating the modifications listed in the articles of the Treaty of Lisbon, as well as the annexes and protocols thereto, as they will result from the amendments introduced. It also contains the declarations annexed to the Final Act of the Intergovernmental Conference which adopted the Treaty of Lisbon.
