The 2007 Philippine House of Representatives elections were held on May 14, 2007, to elect members to the House of Representatives of the Philippines to serve in the 14th Congress of the Philippines from June 30, 2007, until June 30, 2010. The Philippines uses parallel voting for seats in the House of Representatives.

The administration-led TEAM Unity maintained control of the House of Representatives although the opposition-backed Genuine Opposition won control of the Senate. Incumbent Speaker Jose de Venecia Jr. of Pangasinan was elected Speaker after being the only one nominated: 186 voted for De Venecia, 1 against (Eduardo Joson) and 24 abstentions.

Electoral system The House of Representatives shall have not more than 250 members, unless otherwise fixed by law, of which 20% shall be elected via the party-list system, while the rest are elected via congressional districts.

In this election, there are 218 seats voted via first-past-the-post in single-member districts. Each province, and a city with a population of 250,000, is guaranteed a seat, with more populous provinces and cities divided into two or more districts.

Congress has the power of redistricting three years after each census.

As there are 218 congressional districts, there shall be 53 seats available under the party-list system. A party has to cross the 2% electoral threshold to win a guaranteed seat. Next, the court ruled that the first-placed party should always have more seats than the other parties, and that the prior 2%–4%–6% method will only be used for the first-placed party. As for parties that got 2% of the vote but did not have the most votes, they will automatically have one more seat, then any extra seats will be determined via dividing their votes to the number of votes of the party with the most votes, then the quotient will be multiplied by the number of seats the party with the most votes has. The product, disregarding decimals (it is not rounded), will be the number of seats a party will get.

The Supreme Court ruled the 2% electoral threshold as unconstitutional in 2009, which then allocated a new way to allocate seats.

Redistricting Reapportioning (redistricting) the number of seats is either via national reapportionment three years after the release of every census, or via piecemeal redistricting for every province or city. National reapportionment has not happened since the 1987 constitution took effect, and aside from piecemeal redistricting, the apportionment was based on the ordinance from the constitution, which was in turn based from the 1980 census.

For this election, 7 new districts were added, with 1 from the 10th Congress, 1 from the immediately preceding 12th Congress, and 5 from the outgoing 13th Congress. Cagayan de Oro, Dinagat Islands, Marikina, Sultan Kudarat, Taguig–Pateros, Zamboanga City and Zamboanga Sibugay all increased their number of districts by one each.

Summary of changes As there were 218 seats from congressional districts, and since the constitution requires that there should be 1 party-list seat for every 4 seats from congressional districts, this means there were 53 party-list seats up for this election, or for a total of 270 seats.

Campaign

Genuine Opposition The Genuine Opposition (GO) targeted to win at least 80 seats to be able to impeach President Gloria Macapagal Arroyo; however the administration's TEAM Unity prevented GO in winning several of those seats by fielding in strong candidates against GO in those districts.

Lakas vs. KAMPI The administration's two main parties, Lakas-CMD and Kabalikat ng Malayang Pilipino (KAMPI), was seen to win majority of the seats, with most contests contested by the two parties. This inevitably produced a split in the administration ranks on who would be their candidate for Speaker in the impending victory. However, the two parties were united in supporting President Arroyo and were able to prevent any impeachment proceeding against her or her allies from reaching the Senate.

Lakas-CMD party leader and House Speaker Jose de Venecia was challenged by KAMPI's Pablo P. Garcia for the speakership in the incoming 14th Congress of the Philippines which has caused a battle between administration allies. Recently, Garcia was accused by Parañaque 1st District Rep. Eduardo Zialcita and Manila 6th District Rep. Bienvenido Abante, Jr. both under the party Lakas-CMD of using Government Service Insurance System or GSIS pension funds care of Garcia's son GSIS Vice-Chairman, General Manager and President Winston Garcia to bribe congressmen of PHP 300,000 to 400,000 to support his father's speakership bid.
