One Vote, Unequal Weight: Party-List Seat Allocation and Equal Protection in Philippine Elections

The Supreme Court has settled a recurring question in Philippine elections: does the formula for allocating additional party-list seats violate the constitutional right to equal protection? In a ruling dated September 15, 2020, the Court upheld the existing method of seat distribution, rejecting arguments that it double-counts votes in favor of larger party-list groups. The decision clarifies how the party-list system works and why the Court refused to change the rules.

The Dispute Over Additional Seats

The case involved Republic Act No. 7941, the law governing the party-list system. Section 11(b) of this law provides that party-lists receiving at least two percent of the total votes cast are entitled to one guaranteed seat each. The same provision states that those garnering more than two percent "shall be entitled to additional seats in proportion to their total number of votes."

Petitioners ANGKLA, Serbisyo sa Bayan Party, and Aksyon Magsasaka-Partido Tinig ng Masa argued that this formula results in the double-counting of votes. Under their proposed framework, the votes used to secure a guaranteed seat in the first round should be deducted before computing additional seats in the second round. They claimed this would give smaller party-lists a fairer chance at representation.

The petitioners also challenged the results of the May 13, 2019 party-list elections. They argued that under their proposed formula, they would have been entitled to seats that were instead allocated to other party-list groups.

The Court's Ruling

The Supreme Court dismissed the petitions. The Court held that the petitioners failed to meet the requirements for judicial review, particularly the requirement that a constitutional question be raised at the earliest possible opportunity.

The Court noted that RA 7941 was enacted in 1995 and that the interpretation of Section 11(b) was already settled in the landmark case of BANAT v. COMELEC in 2009. The petitioners had benefited from this interpretation in previous elections. ANGKLA was proclaimed a winning party-list in 2013 and 2016, while SBP secured a seat in 2016.

The Court emphasized that the petitioners only questioned the formula after they lost in the 2019 elections. Justice Mario Victor Leonen observed that an electoral system must remain objective and neutral, and cannot be upheld at one instance and assailed at another based on how a party fares.

The Court also applied the doctrine of estoppel, noting that the petitioners had previously defended the BANAT formula when it worked in their favor. As the Court stated, "he who comes to court must come with clean hands."

The Two-Round Allocation System

Despite dismissing the petitions on procedural grounds, the Court took the opportunity to explain the correct application of Section 11(b) as settled in BANAT.

The allocation of party-list seats follows a two-round process. In the first round, party-lists receiving at least two percent of the total votes cast are each guaranteed one seat. In the second round, the remaining available seats are distributed by multiplying each party-list's percentage of votes by the number of remaining seats. All participating party-lists, regardless of their vote percentage, may participate in this round.

The Court explained that this formula gives effect to the constitutional mandate that party-list representatives comprise twenty percent of the House of Representatives. The Constitution gives Congress the discretion to determine how party-lists qualify for seats, and the Court has consistently upheld the BANAT formula as the correct interpretation.

No Equal Protection Violation

The Court rejected the claim that the allocation formula violates the equal protection clause. The distinction between party-lists that received at least two percent of the votes and those that did not is substantial and justified. Party-lists with a clearer mandate from the people may reasonably receive additional benefits.

The Court also noted that the petitioners' proposed formula would favor minimally-representative and unpopular party-lists, which runs contrary to the purpose of the party-list system to ensure the broadest possible representation.

Practical Takeaways

• The party-list seat allocation formula under RA 7941, as interpreted in BANAT, remains valid and constitutional.
• The two-round system ensures that the twenty percent constitutional allocation for party-list representatives can be fully achieved.
• Parties that benefit from a judicial interpretation of a law cannot later challenge that interpretation when it no longer favors them.
• Constitutional challenges must be raised at the earliest opportunity, not only when a party experiences an unfavorable outcome.
• The equal protection clause does not require absolute proportional representation in the party-list system.
