On November 20, 2008, the Parliament of Sweden approved the European Union reform charter, popularly referred to as the Treaty of Lisbon [PDF]. The vote in the Riksdag was heavily in favor of ratification and made Sweden the twenty-fourth country to adopt the measure, which was aimed at strengthening the executive powers within the EU. The Treaty of Lisbon was signed by the respective leaders of the EU member-states in December 2007. It took legal effect on December 1, 2009 after it had been ratified by all of the member-states.
