Dec. 1, 2009: After Years of Rejection and Delay, the Lisbon Treaty Takes Effect and the European Union Gets a New Set of Rules
On Dec. 1, 2009, the Treaty of Lisbon entered into force, closing out a decade of institutional wrangling inside the European Union. There were no parades. The change arrived as a calendar turnover, and it rewired how 27 member states made decisions.
The Long Road
The treaty had been signed in Lisbon on Dec. 13, 2007, after the failure of a more ambitious EU constitution that French and Dutch voters had rejected in 2005. Lisbon was meant to be the leaner replacement, a set of amendments to existing treaties rather than a grand founding document. It still needed ratification in every member state, and Ireland, the only country to put it to a popular vote, rejected it in June 2008. Brussels was left with a treaty that could not take effect. Ireland held a second referendum in October 2009, after securing assurances on issues such as taxation and neutrality, and voters approved it by a wide margin. The Czech Republic was the last holdout. President Václav Klaus, a prominent critic of the treaty, signed it on Nov. 3, 2009, only after the Czech Constitutional Court cleared it. After more than two years of stalling, the final obstacle was a signature.
With the treaty in force, the EU created two new jobs. Belgian Prime Minister Herman Van Rompuy, chosen by national leaders at a Brussels dinner on Nov. 19, became the first full-time President of the European Council. Britain's Catherine Ashton became the High Representative for foreign affairs and security policy. Both appointments surprised many observers, who had expected bigger names. The treaty also expanded the European Parliament's powers and changed voting rules among governments. Its most famous provision may be Article 50, which set out for the first time how a member state could leave the Union. It looked like a procedural footnote in 2009. Seven years later, the United Kingdom would invoke it.
