Bagabuyo vs. COMELEC

Legislative apportionment or reapportionment under Article VI, Section 5 does not require a plebiscite because legislative districts are merely representative units, not corporate entities or local government units; the plebiscite requirement under Article X, Section 10 applies only to the creation, division, merger, abolition, or substantial alteration of boundaries of provinces, cities, municipalities, or barangays.

Cagayan de Oro City was previously a lone legislative district represented by one congressman and 12 city councilors. In 2006, Congress enacted R.A. No. 9371 to apportion the city into two legislative districts, effectively doubling its representation in Congress and increasing city council seats from 12 to 16 (8 per district).

• October 10, 2006: Congressman Constantino Jaraula filed House Bill No. 5859, which became R.A. No. 9371
• March 13, 2007: COMELEC en Banc promulgated Resolution No. 7837 implementing R.A. No. 9371
• March 27, 2007: Petitioner filed petition for certiorari, prohibition, and mandamus with the SC
• April 10, 2008: Petitioner amended petition to include additional respondents (Executive Secretary, DBM Secretary, COA Chairman, Cagayan de Oro City officials)
• May 14, 2007: National and local elections proceeded under the new apportionment (no TRO issued)

• Nature of Action: Special civil action for certiorari, prohibition, and mandamus assailing constitutionality of R.A. No. 9371 and COMELEC Resolution No. 7837
• Petitioner: Rogelio Z. Bagabuyo, voter and taxpayer of Cagayan de Oro City
• Respondent: Commission on Elections (COMELEC), later joined by Executive Secretary Eduardo Ermita, DBM Secretary, COA Chairman, and Cagayan de Oro City officials
• R.A. No. 9371: Apportioned Cagayan de Oro into District 1 (23 rural barangays) and District 2 (16 barangays plus 40 urban barangays), effective for May 2007 elections
• Alleged Inequality: District 1 had 93,719 registered voters; District 2 had 127,071 registered voters (based on 2007 data, actual population was 254,644 for District 1 and 299,322 for District 2)
• Effect on Sangguniang Panglungsod: Increased representation from 12 to 16 councilors (8 per district) pursuant to R.A. No. 6636

• R.A. No. 9371 effectively divides and converts Cagayan de Oro as a local government unit, requiring a plebiscite under Article X, Section 10 of the Constitution
• The law arbitrarily reduces voters' sovereign power by limiting them to vote only for representatives in their designated district
• The apportionment violates the equality of representation doctrine due to disparity in number of voters between districts (93,719 vs. 127,071)
• Government funds were illegally disbursed without prior approval by the sovereign electorate
• Direct invocation of SC jurisdiction is proper under Del Mar v. PAGCOR due to compelling reasons and importance of issues

• Petitioner violated the hierarchy of courts since the RTC has concurrent jurisdiction over constitutional challenges to statutes
• R.A. No. 9371 merely increases representation in Congress and Sangguniang Panglungsod pursuant to Article VI, Section 5, not a division of the city as a local government unit under Article X, Section 10
• No plebiscite is required because the city's territory, population, and income classification remain unchanged; no new local government unit is created
• Criteria under Article X, Section 10 apply only to creation, division, merger, abolition, or substantial alteration of boundaries of LGUs

• Procedural Issues:
  • Whether the petitioner violated the hierarchy of courts rule by directly filing with the SC instead of the RTC
• Substantive Issues:
  • Whether R.A. No. 9371 merely provides for legislative reapportionment or involves the division/conversion of a local government unit requiring a plebiscite
  • Whether R.A. No. 9371 violates the equality of representation doctrine

• Procedural: The SC did not dismiss the petition despite the hierarchy of courts rule. Direct invocation of the SC's original jurisdiction is allowed when there are special and important reasons, such as petitions assailing the validity of legislative enactments by lawmakers. Additionally, as an action against a COMELEC en banc resolution, the case falls under Rule 64 requiring SC review.
• Substantive:
  • Legislative Apportionment vs. LGU Division: R.A. No. 9371 is purely legislative reapportionment under Article VI, Section 5, not a division of the city under Article X, Section 10. No plebiscite is required.
  • Legislative districts are representative units, not corporate units or political subdivisions through which government functions are carried out
  • Unlike LGUs, legislative districts have no separate juridical personality, no chief executive, and no capacity to act for and in behalf of constituents
  • The city remains a single political and corporate unit; its territory remains whole and intact
  • The increase in Sangguniang Panglungsod seats is an effect of R.A. No. 6636, not a division of the city
  • Equality of Representation: No violation. The Constitution requires equality of representation based on number of inhabitants, not registered voters. Mathematical exactitude is not required; disparity is permissible as long as districts comprise, as far as practicable, contiguous, compact, and adjacent territory.

• Legislative Apportionment vs. Creation/Division of LGUs — Legislative apportionment (Article VI, Sec. 5) concerns allocation of seats in legislative bodies to equalize population and voting power among districts. Creation/division of LGUs (Article X, Sec. 10) concerns commencement, termination, or modification of corporate existence and territorial coverage of provinces, cities, municipalities, or barangays. Only the latter requires a plebiscite.
• Representative Unit vs. Corporate Unit — Legislative districts are representative units for electing congressmen; they are not corporate units with legal personality, territorial boundaries for governance purposes, or chief executives. LGUs are corporate units with legal personality, territorial boundaries, and chief executives (governors, mayors, punong barangays).
• Equality of Representation — The Constitution requires that legislative districts be apportioned based on number of inhabitants, not registered voters. Districts must comprise, as far as practicable, contiguous, compact, and adjacent territory. Mathematical exactitude or rigid equality is not required; practical approximation suffices.

• "Legislative apportionment is defined... as the determination of the number of representatives which a State, county or other subdivision may send to a legislative body... The aim of legislative apportionment is 'to equalize population and voting power among districts.'"
• "A pronounced distinction between Article VI, Section 5 and Article X, Section 10 is on the requirement of a plebiscite... no plebiscite requirement exists under the apportionment or reapportionment provision."
• "Legislative districts... are not corporate units... Unlike a province, which has a governor; a city or a municipality, which has a mayor; and a barangay, which has a punong barangay, a district does not have its own chief executive."
• "The Constitution... does not require mathematical exactitude or rigid equality as a standard in gauging equality of representation."

• Tobias v. Abalos — Controlling precedent establishing that no plebiscite is required for legislative reapportionment; the plebiscite in that case was for conversion of Mandaluyong into a highly urbanized city, not for the creation of a new legislative district.
• Macias v. COMELEC — Historical roots of apportionment provision; equality of representation is a justiciable issue.
• Montejo v. COMELEC — Reiterated that inequality of representation is justiciable; standards for reapportionment.
• Herrera v. COMELEC — Basis for districting is the number of inhabitants, not registered voters.
• Del Mar v. PAGCOR — Cited by petitioner for direct invocation of SC jurisdiction in cases of compelling reasons.

• Article VI, Section 5(1), (3), and (4) of the 1987 Constitution — Mandates apportionment of legislative districts among provinces, cities, and Metro Manila based on inhabitants; requires districts to comprise contiguous, compact, and adjacent territory; mandates reapportionment within 3 years after return of every census.
• Article X, Section 10 of the 1987 Constitution — Requires plebiscite for creation, division, merger, abolition, or substantial alteration of boundaries of provinces, cities, municipalities, or barangays.
• Section 7 and 10 of R.A. No. 7160 (Local Government Code) — Specifies income, population, and land area as criteria for creation/division of LGUs; implements plebiscite requirement.
• Section 3 of R.A. No. 6636 — Provides for allocation of Sangguniang Panglungsod seats based on number of legislative districts.
• Rule 64 of the Rules of Court — Requires SC review of judgments or final orders of COMELEC en banc in election contests.
