Case Digest (G.R. No. 188078)
Expanded Legal Reasoning Model

Facts:

  • Background of the Case
    • The case involves a motion for reconsideration filed by the respondent Commission on Elections (COMELEC) concerning a Decision dated January 25, 2010.
    • The petitioners are Victorino B. Aldaba, Carlo Jolette S. Fajardo, Julio G. Morada, and Minerva Aldaba Morada.
    • The motion for reconsideration was originally denied in a prior resolution, and the COMELEC now raises similar arguments to challenge the decision.
  • Legislative and Population Data Framework
    • Congress enunciated Republic Act No. 9591 which created a legislative district for Malolos City.
    • To comply with the constitutional requirement under Section 5(3), Article VI of the 1987 Constitution, Congress relied on population indicators.
      • These indicators included the Certification of Alberto N. Miranda of the National Statistics Office (NSO), projecting the 2010 population of Malolos City.
      • Additional sources cited were the 2007 Census of Population – PMS 3 – Progress Enumeration Report and certifications from the City of Malolos’ Water District (dated July 31, 2008) and the Liga ng Barangay (dated August 22, 2008).
  • COMELEC's Arguments and Concerns
    • The COMELEC argued that the reliability and authoritativeness of the population indicators used by Congress are non-justiciable matters.
    • It contended that population data, being dependent on varying sources and methods, should be insulated from judicial determination.
    • The COMELEC also emphasized that alternative population indicators, which show different population figures, further highlight the non-justiciability of the matter.
  • Issues Regarding Data Reliability and Methodology
    • The Certification by Miranda was challenged on the ground that it did not comply with Executive Order (EO) No. 135, which sets strict protocols:
      • Population certifications for intercensal years should be based on official demographic projections by the National Statistical and Coordination Board (NSCB).
      • Such certifications need to utilize data as of the middle of the year and must be issued by the designated certifying officer of the NSO.
    • Based on Miranda’s projection (using a growth rate of 3.78%), Malolos City’s population as of August 1, 2010, would only reach 249,333—below the statutory threshold of 250,000.
    • The additional documents—the 2007 census report, the certification from the Water District, and that from the Liga ng Barangay—were deemed unreliable because:
      • They do not comply with the criteria for authoritative population indicators set by EO 135.
      • They represent data collected by non-NSO entities which lack the requisite statistical expertise and proper authorization.
  • Constitutional and Geographical Issues
    • The creation of a legislative district requires strict adherence to the constitutional mandate: only cities with at least 250,000 constituents are entitled to representation in Congress.
    • The decision complained of not only the failure to meet the population threshold but also the improper geographic configuration:
      • The carving out of Malolos City from the former First Legislative District left the town of Bulacan isolated rather than part of a contiguous, compact, and adjacent territory.
    • The case also revisits the principle that even apportionment laws, though inherently political, remain subject to judicial review when constitutional limitations are at issue.

Issues:

  • Justiciability Issue
    • Whether the population indicators used by Congress to create the legislative district are non-justiciable matters.
    • Whether judicial review can extend to examining the reliability and authoritativeness of these statistical inputs.
  • Reliability and Authoritativeness of Population Data
    • Whether the certification of projected population by Miranda, and the other population indicators (2007 Census, Water District, Liga ng Barangay), meet the stringent requirements under EO 135.
    • Whether the failure to adhere to EO 135’s mandates invalidates the population data relied upon for legislative apportionment.
  • Compliance with Constitutional Requirements
    • Whether Malolos City satisfies the constitutional threshold of 250,000 constituents for representation in Congress.
    • Whether the creation of the legislative district adheres to the geographical requirement of contiguous, compact, and adjacent territory as mandated by Section 5(3), Article VI of the Constitution.
  • Abuse of Discretion and Judicial Review Power
    • Whether denying judicial review on the basis of the matter being “political” undermines the constitutional duty of the courts to ensure compliance with specified limitations in the creation of legislative districts.
