The13th Congress of the Philippines (Filipino:Ikalabintatlong Kongreso ng Pilipinas), composed of thePhilippine Senate andHouse of Representatives, met from July 26, 2004, until June 8, 2007, during the fourth, fifth, and sixth years ofGloria Macapagal Arroyo's presidency. The convening of the 13thCongress followed the2004 national elections, which replaced half of the Senate membership and the entire membership of the House of Representatives.
PresidentGloria Macapagal Arroyo, in her severalState of the Nation Addresses has repeatedly called onCongress to pave the way for the amending of the1987 Constitution[1] to provide for aunicameral–parliamentary–federalform of government. On December 8, 2006, theadministration-dominatedHouse of Representatives, bypassing theSenate, passed in hasteHouse Resolution 1450, which called on Congress to convene into aConstituent Assembly (ConAss) to propose amendments to the Constitution.[2]The House move however, was faced with stiff opposition from the outmaneuvered members of theopposition and all but 1 member of the Senate,[3] which was later bolstered by support from several sectors of thecivil society and the influentialRoman Catholic Church,[4] which threatened to hold nationwide protest rallies to denounce the House move.[5] Succumbing to the mounting opposition and the apparent withdrawal of support of thePresident,[6]House SpeakerJose De Venecia later on scrapped the entire resolution and called instead for aconstitutional convention, challenging the Senate to concur it in 72 hours.[7] But this too was rejected by the Senate,[8] which preferred to hold a constitutional convention after the2007 elections.[9] Efforts to amend the constitution during the 13th Congress were eventually shelved.[10]
Laws passed by the 13th Congress: 149 (Republic Act No. 9333 to 9495), as of September 7, 2007[11]
