Ratification of the Treaty of Lisbon

Order in which EU member states ratified the treaty.^[1] Dates refer to the deposition of the ratification instruments with the government of Italy.

The ratification of the Treaty of Lisbon was officially completed by all member states of the European Union on 13 November 2009 when the Czech Republic deposited its instrument of ratification with the Italian government.^[2] The Lisbon Treaty came into force on the first day of the month following the deposition^[3]^[4] of the last instrument of ratification with the government of Italy, which was 1 December 2009.^[5]

Most states ratified the treaty in parliamentary processes. The Republic of Ireland was the only member state to hold a referendum on the subject. In a first vote held on 12 June 2008 (the first Lisbon referendum) the treaty was rejected; however a second vote was held on 2 October 2009 (the second Lisbon referendum) and the treaty was approved.
