G.R. No. L-26959 - Co vs. Commission on Elections

Case Summary (G.R. No. L-26959)

Factual Background

The petitions arose from the enactment of Republic Act No. 6734, which provided for an Organic Act for an Autonomous Region in Muslim Mindanao and specified thirteen provinces and nine cities as constituent units for a plebiscite. The plebiscite was scheduled for November 19, 1989. Petitioners sought injunctive relief to prevent the Commission on Elections from conducting the plebiscite and to restrain the Secretary of Budget and Management from releasing funds for that purpose. Petitioners also sought declarations that R.A. No. 6734, or parts thereof, were unconstitutional.

Procedural Posture

The Solicitor General filed a consolidated comment on behalf of respondents, which the Court treated as an answer. The issues were joined and the case was submitted for decision. Petitioner Mam-o subsequently filed a manifestation and a motion for leave to reply and to open oral arguments, which the Court noted. The petitions were consolidated for resolution of the constitutional questions presented.

Issues Presented

The petitions posed two principal categories of challenges: first, that R.A. No. 6734, or parts thereof, violated provisions of the 1987 Constitution governing creation and powers of autonomous regions; and second, that certain provisions of R.A. No. 6734 conflicted with the Tripoli Agreement, which petitioners presumed to be a binding international agreement that should control the Organic Act.

Petitioners' Contentions Regarding the Tripoli Agreement

Petitioners contended that the Tripoli Agreement was a binding international instrument and that certain provisions of R.A. No. 6734 conflicted with it. They argued that, if the Tripoli Agreement were binding, it would constrain the legislative scheme enacted in the Organic Act and warrant enjoining implementation of the plebiscite and the Act.

Court's Preliminary Observations on the Tripoli Agreement

The Court observed that the Solicitor General denied that the Tripoli Agreement constituted a binding treaty of the Republic because it was not entered into with a sovereign state nor ratified under the 1973 or 1987 Constitutions. The Court deemed it unnecessary and non-determinative to decide the Tripoli Agreement's international legal status. The Court explained that, regardless of the Tripoli Agreement's character, the appropriate and controlling standard for assessing R.A. No. 6734 is the 1987 Constitution. If the Agreement were part of internal law, it would be in the same class as an act of Congress and could be amended by subsequent legislation; thus R.A. No. 6734, as a subsequent enactment, would stand unless shown to contravene the Constitution.

Constitutional Arguments Challenging R.A. No. 6734

Petitioners advanced several constitutional objections. One allegation, by petitioner Abbas, was that R.A. No. 6734 unconditionally created an autonomous region, contrary to Article X, Section 18 of the 1987 Constitution, which conditions creation on approval in a plebiscite. Petitioner Mama-o argued that Congress exceeded its power by including in the Organic Act provinces and cities that do not share the common and distinctive historical and cultural heritage and other characteristics specified by the Constitution. Petitioners also invoked Article III, Section 5 on freedom of religion against provisions that would require Shari’ah or Tribal Code tribunals to apply national law in cases of conflict. Additional challenges targeted Article XIX, Section 13 of the Organic Act for purportedly vesting the President with power to merge regions in contravention of Article X, Section 10, and attacked provisions creating an Oversight Committee that would schedule and supervise transfers of powers and properties as allegedly delaying the effectivity of the autonomous region.

Court's Analysis: Creation and Composition of the Autonomous Region

The Court analyzed the contested provision of R.A. No. 6734 that declared the Autonomous Region in Muslim Mindanao created to be composed of provinces and cities voting favorably in the plebiscite, and it reconciled that language with Article X, Section 18 of the 1987 Constitution. The Court found that the Organic Act expressly referenced the constitutional requirement and contained a transitory provision (Article XIX, Section 13) that mirrored the constitutional condition: the autonomous region would take effect only upon approval by a majority of votes cast by the constituent units in a plebiscite and that only provinces and cities voting favorably would be included. The Court therefore held that R.A. No. 6734 did not unconditionally create an autonomous region independent of the plebiscitary requirement in the Constitution.

Court's Analysis: Majority Requirement in the Plebiscite

The Court confronted the question whether the Constitution requires a majority of all votes cast across constituent units or a majority within each constituent unit for creation and inclusion. Comparing the Constitution’s phrasing on plebiscites for other purposes, the Court concluded that Article X, Section 18 requires a simple majority approving the Organic Act in individual constituent units. The Court reasoned that the draftsmen would have used language analogous to Article XVIII, Section 27 if they intended a majority of the totality of votes. The Court therefore held that the constitutionally mandated approval depends on the majority will in individual constituent units, and that only provinces and cities voting favorably would be included in the Autonomous Region.

Court's Analysis: Standards for Congressional Determination of Areas

Addressing petitioner Mama-o’s contention that Congress improperly included areas that do not share the requisite common characteristics, the Court emphasized that the Constitution supplies criteria for Congress to ascertain which areas may constitute the autonomous region. The Court held that the determination of which areas meet those criteria is a legislative factfinding and a matter within Congress’s discretion. Judicial review cannot substitute the Court’s judgment for that of the Legislature without violating the separation of powers. The Court cited precedent recognizing the limited role of the judiciary in reviewing such legislative determinations and concluded that Congress’s classification was a reasonable exercise of its constitutional prerogative.

Court's Analysis: Free Exercise of Religion Claim

On the facial challenge invoking Article III, Section 5 (free exercise of religion), the Court noted that petitioners premised the objection on hypothetical conflicts between the Muslim Code or a Tribal Code and national law, and on the contention that Islamic law is divine and thus immune from man-made laws. The Court observed that judicial power requires an actual controversy involving legally demandable rights. Because no concrete case involving a conflict had arisen, the Court declined to decide an abstract question concerning potential violations of religious freedom and thus did not sustain the constitutional objection on that ground.

Court's Analysis: Presidential Power to Merge Regions

Petitioners argued that Article XIX, Section 13’s proviso permitting the President to merge existing regions usurped powers reserved by Article X, Section 10. The Court clarified that the referenced mergers concern administrative regions—groupings of contiguous provinces used for administrative purposes—not the creation, division, merger, or abolition of territorial and political subdivisions such as provinces, cities, municipalities, or barangays. The Court observed that administrative regions have traditionally been subject to presidential admini

Article XIX, Sec. 13 of the Organic Act reiterated the plebiscite condition and contained a proviso authorizing the President to merge existing administrative regions by administrative determination.
The Organic Act also provided for an Oversight Committee to supervise transfer of powers, appropriations, and properties to the regional government and set a six-year period for such transfers.
