Proportion of votes (inner ring) as compared to the proportion of seats (outer ring). Each party is given one color and one slice, and are arranged in descending order of votes. The parties that did not win a seat is given a single slice and color (gray).
Provincial results: Parties that won at least a plurality of the vote in each province. Note that election is not via per province but nationwide as a single at-large "district".
Candidates from the district elections are not allowed to be nominated by the parties participating in the party-list election, nor are parties who have candidates in the district elections may be allowed to join the party-list election; the parties in the party-list election must represent a distinct "sector" in the society such as women, laborers and the like.
In the election, the voter elects the party, not the nominees of the party; a voter may not be able to influence how the nominees are listed on election day, except for joining the party beforehand. If the party surpasses 2% of the national vote, the person first nominated by the party will be seated. Additional seats can be won by multiplying the percentage of the votes the party got, with the difference of number of seats the party already has (1), and the number of seats allocated for sectoral organizations (57), disregarding decimals, with no party getting more than two additional seats. However, usually only the party with the most number of votes gets the two additional seats, the other parties will get only one additional seat. If the number of seated representatives is less than the 20% quota of party-list representatives in Congress (57 for the 15th Congress), the unfilled seats will be filled up by the remaining parties in descending order of votes garnered until are seats are filled up. Note that with more than a hundred parties participating, and with the 3-seat cap, the seats that the parties with 2% of the vote or more will always be less than the 20% allocation.
Prior to the election, the Commission on Elections (COMELEC) expected an increase of party-list organizations seeking accreditation from the 153 organizations that applied for accreditation during the 2007 elections. The COMELEC also de-listed 25 party-list organizations for either failing to participate in the last two elections or did not obtain two percent of the votes cast. However, the COMELEC said the two percent vote requirement does not cover the organizations that won a congressional seat based on a recent Supreme Court ruling. Militant groups Migrante and Sanlakas protested such de-listment, saying that they were not covered by the 2% rule, and that such rule is unconstitutional. Another 8 such organizations also filed a motion for reconsideration or a verified opposition against their de-listment.
In December, the commission en banc denied Ang Ladlad's motion for reconsideration with finality as Remoto said he would elevate the case to the Supreme Court. In January 2010, the Supreme Court issued a temporary restraining order to the COMELEC on disqualifying Ang Ladlad.
With the COMELEC prevented from disqualifying Ang Ladlad, the organization along with 143 others were included in the final list of accredited party-list organizations, although the status may change if the court sides with COMELEC on the issue. Under Resolution 8745, six additional party-list groups were accredited, bringing the total to 150.
The party-list election has been hit by allegations that several parties are fronts by the ruling administration. Bagong Alyansang Makabayan (BAYAN), a coalition of left-leaning party-lists, and election watchdog Kontra Daya said that nine party-lists are connected to the Arroyo political family. The parties and their first nominee cited are:
Ang Galing Pinoy, a party that claims to represents security guards: outgoing second district of Pampanga congressman Mikey Arroyo. Arroyo, the son of president Gloria Macapagal Arroyo willingly dropped his intention to run in Pampanga's 2nd district to let his mother run.
The administration distanced itself from the six pro-government parties insisting it has not endorsed any group supposedly to augment the administration's representation in Congress, saying that "it is up to the COMELEC to judge and issue a decision on the matter."
On April 8, 2010, the Supreme Court ruled that Ang Ladlad is allowed to run in the 2010 election, saying with a unanimous vote that what is immoral is not necessary illegal.
On May 31, the leading parties in the party-list election were declared by the commission as winners; deferred are the parties (not nominees) that have pending disqualification cases against them. Ang Galing Pinoy's proclamation, the party of incumbent Pampanga 2nd district representative Mikey Arroyo was recalled as Arroyo has a pending disqualification notice against him, and he is their #1 nominee. The winners are:
Incumbents nominated by their parties are italicized; proclaimed winners are boldfaced. Seats in parenthesis indicates the number of seats to be won by the party pending disqualification cases, while parties highlighted are disqualified prior to the election.
*there are more nominees listed in case one of the first three nominees are either disqualified or are removed from office. In some instances, the parties submitted two lists; in those the cases, the second list submitted is listed.
On July 11, 2010, the Commission on Elections (COMELEC) disqualified two nominees of Kasangga sa Kaunlaran namely Teodoro Haresco and Eugenio Lacson on proving they do not support the marginalized sectors. Bagong Alyansang Makabayan (BAYAN) secretary-general Renato Reyes says that "this should now serve as a benchmark for other pending petitions against party-list nominees who do not belong to nor represent the marginalized sectors".
On July 20, 2010, the COMELEC allowed Rep. Arroyo to sit as the representative for Ang Galing Pinoy after he was accepted as the first nominee of the party-list group. The Commission voted 4–2 while one abstained. The COMELEC also proclaimed three more parties as winners: A TEACHER, Butil Farmers Party and 1-UTAK, although the latter's first nominee, Angelo Reyes, was allowed to take office as he has a pending disqualification case.
While the commission upheld Angelo Reyes nomination by 1-UTAK, on late July, the party withdrew Reyes from their list after the commission's decision was appealed. Reyes, who was prohibited from having his seat at the House of Representatives, appealed to the Supreme Court. With the suicide of Reyes, the Supreme Court dismissed Reyes' petition.
The Supreme Court dismissed petition filed by the Alliance for Barangay Concerns (ABC) on their disqualification by the commission, on March 22. The commission's decision, in which ABC was disqualified for being a front of the Members Church of God International, a religious group that produces the Ang Dating Daan television program, was upheld as it stated that the constitution gave the commission the power to register and cancel the registration of party-list groups. The commission originally dismissed the petition filed by lawyer and journalist Melanio Mauricio, Jr. in 2010, but was reconsidered on August 2010; ABC has already won a seat in Congress but has not been sworn in. ABC, through its chairman James Marty Lim, argued that since the party had already won a seat, the jurisdiction should be under the House of Representatives Electoral Tribunal. However, the court ruled that commission maintains jurisdiction as the case does not refer to qualifications of members of Congress.
