Province of Sulu vs. Medialdea

The Constitution requires that for an autonomous region to be created, each constituent province, city, or geographic area must individually and favorably vote for its inclusion in a plebiscite. The BOL's provision treating the entire ARMM as a single geographical area for voting purposes is unconstitutional as it overrides the will of a constituent unit that voted against inclusion.

The Bangsamoro Organic Law is the culmination of decades of peace negotiations between the Philippine government and the Moro Islamic Liberation Front (MILF). It seeks to replace the Autonomous Region in Muslim Mindanao (ARMM) with a new political entity, the BARMM, granting it more expansive autonomy. The law was ratified in a two-part plebiscite in 2019. The Province of Sulu, part of the original ARMM, voted against the BOL but was nonetheless included in BARMM because the law treated the entire ARMM as one voting unit.

• Filed directly with the Supreme Court via Petitions for Certiorari and Prohibition under Rule 65.
• Multiple petitions (G.R. Nos. 242255, 243246, 243693) and interventions were consolidated.
• The SC gave due course to the petitions and required memoranda from all parties.
• The plebiscite was conducted on January 21 and February 6, 2019, and BARMM was subsequently inaugurated on March 2, 2019.

• The Bangsamoro Organic Law (RA 11054) was enacted on July 27, 2018, to create the BARMM.
• Article XV, Section 3(a) of the BOL provided that the provinces and cities of the ARMM would "vote as one geographical area" in the plebiscite.
• In the January 21, 2019 plebiscite, the ARMM as a whole voted in favor of the BOL (1,540,017 "Yes" vs. 198,750 "No").
• The Province of Sulu, however, rejected the BOL (137,630 "Yes" vs. 163,526 "No").
• Despite its negative vote, Sulu was included in BARMM by virtue of the "vote as one" provision.

• The BOL is unconstitutional because it abolishes the ARMM, a constitutional creation, without a constitutional amendment.
• The parliamentary form of government in BARMM violates the constitutional requirement that the executive and legislative branches be "elective and representative."
• Automatically including the ARMM in BARMM and treating it as one voting unit violates the right of suffrage and local autonomy of its constituent units, particularly Sulu.
• The designation of the MILF to lead the Bangsamoro Transition Authority violates the equal protection clause.
• The BOL erases the identity and autonomy of indigenous cultural communities in Sulu.

• Congress has plenary power to amend or repeal the organic act creating the ARMM; it is a statutory, not a constitutional, creation.
• The BOL fulfills the constitutional mandate for an autonomous region in Muslim Mindanao.
• The parliamentary system is constitutional as the Constitution does not prescribe a specific form of government for autonomous regions.
• The "vote as one" provision is a valid exercise of legislative discretion and does not violate the equal protection clause.
• The BOL contains ample safeguards for the rights of indigenous peoples.

• Procedural Issues:
  • Whether the petitions present a justiciable controversy.
  • Whether petitioners have legal standing.
  • Whether the issues were raised at the earliest opportunity and constitute the lis mota of the case.
• Substantive Issues:
  • Whether the BOL unconstitutionally abolishes the ARMM.
  • Whether the inclusion of the Province of Sulu in BARMM despite its negative vote is unconstitutional.
  • Whether the parliamentary form of government in BARMM violates the Constitution.
  • Whether the BOL violates the rights of indigenous peoples.

• Procedural: The SC has jurisdiction. The Province of Sulu's petition presents an actual case or controversy regarding the violation of its constituents' right of suffrage. PHILCONSA's petition was dismissed for lack of standing. The Dimaporos' petition was dismissed as moot.
• Substantive:
  1. On the ARMM and the BOL's Validity: Congress has the power to enact, amend, or repeal the organic act for autonomous regions. The ARMM was created by statute (RA 6734, as amended by RA 9054), not by the Constitution itself. Thus, the BOL validly repealed the ARMM organic acts.
  2. On the Inclusion of Sulu: The BOL's provision (Article XV, Section 3(a)) treating the ARMM as "one geographical area" for voting is unconstitutional. Article X, Section 18 of the Constitution explicitly states that "only provinces, cities, and geographic areas voting favorably in such plebiscite shall be included in the autonomous region." Sulu's negative vote must be respected. Its inclusion in BARMM is void.
  3. On the Parliamentary System: The Constitution does not prescribe a specific form of government (presidential or parliamentary) for autonomous regions. It only requires that the executive department and legislative assembly be "elective and representative." BARMM's parliamentary system, where the Chief Minister is elected by the Parliament which is itself elected by the people, satisfies this requirement.
  4. On Indigenous Peoples' Rights: The BOL does not erase indigenous identity. It contains multiple provisions recognizing and protecting the rights of non-Moro indigenous peoples, including reserved parliamentary seats, recognition of native titles, and the creation of a dedicated ministry.

• Constitutional Mandate for Plebiscite in Autonomous Region Creation — The creation of an autonomous region requires a plebiscite, and its effectiveness is contingent upon the approval of a majority of votes cast in each constituent unit. Only those units that vote favorably are included.
• Distinction Between Autonomous Regions and Local Government Units — Autonomous regions, created by organic acts subject to plebiscite, possess a higher degree of autonomy and a distinct constitutional framework compared to provinces, cities, municipalities, and barangays, which are governed by the Local Government Code.
• Plenary Power of Congress over Organic Acts — Congress has the authority to enact, amend, or repeal the organic act for autonomous regions, as these are legislative creations.

• "The inclusion of Sulu in BARMM, despite its constituents' rejection in the plebiscite, is therefore unconstitutional."
• "The right of suffrage of petitioner's constituents should not have been trampled upon. By granting the petition of the Province of Sulu, we uphold the sacrosanct sovereign power of its constituents in the context of the plebiscite."
• "The Constitution does not envisage any state within this jurisdiction other than the Philippine state."

• Province of North Cotabato v. GRP (589 Phil. 387, 2008) — Cited to show that the concept of an "associative state" is unconstitutional and that the President has the authority to conduct peace negotiations, but Congress is not bound by the resulting agreements.
• Disomangcop v. Secretary Datumanong (486 Phil. 398, 2004) — Cited for the principle that organic acts ratified by plebiscite hold significance beyond ordinary statutes and for the discussion on regional autonomy and decentralization.
• Abbas v. COMELEC (258-A Phil. 870, 1989) — Cited to underscore that the will of the majority in each geographical area determines its inclusion in an autonomous region.

• 1987 Constitution, Article X, Section 18 — Provides for the creation of autonomous regions through an organic act enacted by Congress, subject to a plebiscite where "only provinces, cities, and geographic areas voting favorably... shall be included."
• Republic Act No. 11054 (Bangsamoro Organic Law), Article XV, Section 3(a) — The assailed provision that directed the ARMM to "vote as one geographical area."
• Republic Act No. 11054, Article III, Sections 1 & 2 — Defines the territorial jurisdiction of BARMM, which originally included the Province of Sulu.

• Justice Dimaampao (Concurring) — Emphasized the deliberations of the 1986 Constitutional Commission, which clearly intended that the majority vote must be determined with respect to each constituent unit, not the entire proposed region. Cited Abbas v. COMELEC to support this interpretation.

• N/A (The decision was unanimous on the core issue regarding Sulu's inclusion, with one separate concurring opinion).
