Remand and Redistricting: The Supreme Court's Ruling on BAA 77 and BARMM Elections

The Supreme Court's September 30, 2025 decision in Ali, Jr. v. Bangsamoro Transition Authority Parliament (G.R. Nos. E-02219 and E-02235) struck down Bangsamoro Autonomy Act No. 77 (BAA 77), the "Bangsamoro Redistricting Act of 2025," as unconstitutional. The ruling also effectively prevented the conduct of the October 13, 2025 Bangsamoro Autonomous Region in Muslim Mindanao (BARMM) parliamentary elections under either BAA 77 or its predecessor, BAA 58. For businesses, voters, and political stakeholders in the BARMM, the decision clarifies the limits of regional legislative power and the importance of orderly electoral processes.

Background: The Road to BAA 77

The case arose from a complex timeline. Republic Act No. 11054, the Bangsamoro Organic Law, established the BARMM and provided for a transition period governed by the Bangsamoro Transition Authority (BTA). The first regular parliamentary elections were postponed several times, eventually set for October 13, 2025.

In 2024, the Supreme Court's ruling in Province of Sulu v. Medialdea declared the inclusion of Sulu in the BARMM unconstitutional. This left seven parliamentary district seats vacant. To address this, the BTA passed BAA 77 on August 19, 2025, redistricting the remaining provinces and reallocating Sulu's seven seats. The law was signed on August 28, 2025, but its validity was immediately challenged.

The Core Issues

Petitioners raised several constitutional challenges against BAA 77, including:

• Violation of the one-subject-one-title rule under the Bangsamoro Organic Law
• Improper publication under Article 2 of the Civil Code
• Gerrymandering and violation of the right to suffrage
• Unlawful delegation of powers to the President and Congress

The Court consolidated the petitions and issued a temporary restraining order on September 15, 2025, suspending BAA 77's implementation.

The Court's Ruling

The Supreme Court granted the petitions and declared BAA 77 unconstitutional. The Court found that the circumstances did not allow the conduct of the October 13, 2025 elections under either BAA 77 or BAA 58.

Justiciability and Standing

The Court ruled that the petitions satisfied all requisites for judicial review. There was an actual controversy, the petitioners—as registered voters in affected districts and party nominees—had standing, and the constitutional questions were raised at the earliest opportunity. Direct resort to the Court was justified given the genuine constitutional issues, transcendental importance, and the imminent election date.

The One-Subject Rule

On the one-subject-one-title requirement, the Court found no violation. Sections 3, 4, and 5 of BAA 77—dealing with future reallocation, interim appointments, and effects on candidates—all related to the reconstitution of parliamentary districts. Citing Sinsuat v. Ebrahim and Alalayan v. National Power Corporation, the Court explained that the requirement should be given a reasonable, not unduly technical, interpretation.

Publication Requirement

The Court declined to declare BAA 77 ineffective for improper publication. While the petitioners argued that publication should have been in the Official Gazette or a newspaper of general circulation, the Court noted that the Bangsamoro Organic Law and BAA 77 itself provided for publication in the Bangsamoro Gazette or on its official website. The Court did not find this ground sufficient to invalidate the law.

Practical Takeaways

• Regional laws must respect constitutional limits. The BTA's legislative power, while broad, is subject to the Constitution and national laws. Redistricting measures that disenfranchise voters or disrupt elections will face strict scrutiny.
• Timing matters in election law. Enacting a redistricting law during the election period, after the filing of certificates of candidacy, creates serious legal vulnerabilities. The Court emphasized the need for thoroughness and dignity in electoral processes.
• Standing for voters is broad. Registered voters in affected districts have standing to challenge redistricting measures that may affect their right to suffrage.
• The one-subject rule is flexible. As long as provisions relate to the general subject expressed in the title, the rule is satisfied. The Court applies a reasonable, practical interpretation.
• Election preparations require legal certainty. The COMELEC's dilemma—unsure which law governed the elections—underscores the need for timely resolution of constitutional challenges before critical electoral deadlines.
