Expanded Legal Reasoning Model

Facts:

  • Enactment and scope of Batas Pambansa Blg. 885
    • Approved December 3, 1985; created Province of Negros del Norte by separating Silay, Cadiz, San Carlos and seven municipalities from Negros Occidental.
    • Provided plebiscite “in the proposed new province” within 120 days; COMELEC to supervise; funds charged to local treasury.
  • Petitioners’ challenge and procedural history
    • December 23, 1985: residents of Negros Occidental filed prohibition to stop the January 3, 1986 plebiscite, alleging constitutional and LGC infirmities.
    • January 4, 1986: supplemental petition acknowledged plebiscite held, sought prohibition of proclamation and mandamus for a new plebiscite including all qualified voters of Negros Occidental.
  • Respondents’ defense and factual disputes
    • COMELEC and Provincial Treasurer argued presumption of validity, compliance with LGC requisites and that only “areas affected” (i.e., component cities/municipalities) voted.
    • Petitioners produced data showing the new province’s land area ~2,765 km² (

Issues:

  • Whether Article XI, Section 3 of the Constitution required the plebiscite to include all voters in Negros Occidental or only those in the territory to form Negros del Norte.
  • Whether the new province satisfied the LGC area requirement of at least 3,500 km².
  • Whether the petition is moot after the January 3, 1986 plebiscite and the subsequent proclamation and appointments.
