Coseteng vs. Mitra, Jr.
Case
G.R. No. 86649
Decision Date
Jul 12, 1990
Petitioner Coseteng challenged the Commission on Appointments' composition, alleging violation of proportional representation under the 1987 Constitution. The Supreme Court dismissed the petition, ruling the LDP majority's 10 seats and minority allocations complied with constitutional mandates, and KAIBA's minimal representation bound it to majority decisions.

Case Summary (A.C. No. 6490)

Factual Background

The 1987 congressional elections returned House members from multiple parties and coalitions, among them KAIBA, which elected petitioner Coseteng as its sole representative. The House initially elected eleven of its twelve appointees to the Commission on Appointments on August 26, 1987, with a twelfth member elected on September 22, 1987, to represent the minority. After the formation of the Laban ng Demokratikong Pilipino (LDP) on September 16, 1988, a large majority of House members affiliated with the LDP, prompting a reorganization of House committee and Commission on Appointments membership on December 5, 1988.

Procedural History

On February 1, 1989, petitioner Coseteng and KAIBA filed a petition for extraordinary legal writs, treated as a petition for quo warranto and injunction, seeking to annul the election of the twelve House appointees to the Commission on Appointments, to enjoin them from acting as such, and to enjoin other respondents from recognizing them. Respondents filed collective Comments contending that the matter was political and that the reorganization complied with Section 18, Article VI of the 1987 Constitution. Hon. Lorna L. Verano‑Yap filed a separate Comment. The Commission on Appointments took a neutral position, noting related issues pending in Daza v. Singson, G.R. No. 86344.

The Legal Issue

The central question was whether the House members chosen to sit in the Commission on Appointments were elected “on the basis of proportional representation from the political parties” represented in the House, as required by Section 18, Article VI of the 1987 Constitution, and whether petitioner Coseteng and KAIBA were entitled to one of the twelve House seats on that Commission.

Parties' Contentions

Petitioner argued that the reconstituted Commission violated the constitutional mandate of proportional representation because the Coalesced Majority (the LDP majority) was entitled to only nine of the twelve House seats; that members should be nominated by their respective political parties or coalitions; that respondent Verano‑Yap’s election as minority representative was invalid; and that respondent Ablan’s retention as minority member was invalid because neither was properly nominated or elected by the minority. Petitioner asserted support from nine other congressmen for her claim. Respondents countered that the reorganization was strictly consonant with Section 18, Article VI, that the majority coalition could be treated as a political party for apportionment, and that the elections were acts of the House consistent with the Constitution. They also raised the political question doctrine as a preliminary defense.

The Court's Disposition

The Court dismissed the petition for lack of merit. The Court held that the matter was justiciable but that the House reorganization complied with Section 18, Article VI of the 1987 Constitution. The Court ordered costs against the petitioner.

Legal Basis and Reasoning

The Court first observed that the political question defense did not bar judicial review, citing the holding in Daza v. Singson, G.R. No. 86344, that the legality of compliance with the Constitution is justiciable and that the Court has power to determine whether grave abuse of discretion has occurred. On the merits, the Court examined the numerical composition of the House and the LDP majority. The Court accepted the proposition that the LDP controlled approximately 160 of 202 House seats, representing roughly seventy‑nine percent (rounded to eighty percent). Applying proportional representation, eighty percent of the twelve House seats in the Commission equated to 9.6 seats, which the Court rounded to ten seats allocated to the LDP. The remaining two seats were apportioned to the next significant party in the Coalesced Majority, the Liberal Party (held by respondent Verano‑Yap), and to the principal opposition, the KBL (held by respondent Ablan). The Court found this apportionment unquestionably “on the basis of proportional representation of the political parties therein.”

The Court rejected petitioner’s contention that nominations must originate from the political parties. It read Section 18, Article VI to require that the House elect its twelve representatives on the basis of proportional party representation, but not to mandate that parties themselves conduct the internal nomination; the House may nominate through its floor leaders and then elect. The Court found petitioner’s allegation that KAIBA deserved a seat unavailing because KAIBA held only a single seat in the House—less than one percent of membership—and thus fell far short of the approximate eight point four percent threshold the Court identified as necessary to claim proportional entitlement to a seat (i.e., the equivalent of at least seventeen congressmen). The Court further dismissed the evidentiary significance of the nine endorsements for petitioner because those signatories were not me
