The Lisbon Treaty (2009)

View Larger Map of Lisbon

The Lisbon Treaty, signed in 2007 and entered into force on 1 December 2009, raised significant debate among member states and citizens of the European Union. It proposes some quite significant changes to the EU. A number of these changes are very visible and some are more subtle but all are likely to have impact on Europe. This section of this module will highlight the main aspects of the Lisbon Treaty and provide you with the information to help understand the arguments for and against the Lisbon Treaty.

The Lisbon Treaty or the Reform Treaty (to use its official title) was born out of the rejection of a European Constitution by French and Dutch voters in 2005. Many argue that the Lisbon Treaty is not that different from the Constitutional Treaty. This link between the two is denied, however, by many pro-EU politicians.

Given your knowledge of the theories of spillover and ‘unintended consequences’, do you think Mr Hague had grounds to be worried?
