Supreme Court
City of Pasig vs. Commission on Elections
Case
G.R. No. 125646
Decision Date
Sep 10, 1999
Boundary dispute between Pasig and Cainta over proposed barangays; plebiscites suspended pending resolution of territorial jurisdiction.

Case Summary (G.R. No. 125646)

Background and Ordinance Enactments

Pasig City, acting on petitions by residents, enacted:

  1. Ordinance No. 21 (Series 1996) segregating Karangalan Village from Barangays Manggahan and Dela Paz, setting a June 22 plebiscite.
  2. Ordinance No. 52 (Series 1996) creating Barangay Napico, setting a March 15 plebiscite.

COMELEC Petitions by Cainta and Initial Orders

Upon learning of these ordinances, Cainta filed before COMELEC:

  • UND No. 96-016 (June 19, 1996) to suspend Karangalan plebiscite, citing the pending RTC boundary case.
  • UND No. 97-002 (March 12, 1997) to suspend Napico plebiscite on similar grounds.
    COMELEC’s rulings:

  • UND No. 97-002: Petition dismissed as moot after the March 15 plebiscite ratified Napico.

RTC of Negros Oriental, the suspension of administrative actions is proper when a closely related case can directly affect the outcome. Since portions of Karangalan and Napico fall within the disputed area, defining their territorial limits before judicial resolution would be futile.

Requirement of Clear Territorial Boundaries

Under Sec. 386(b) of the Local Government Code, a new barangay’s boundaries must be precisely identified. Judicial precedents (Mariano v. COMELEC) stress that local government units can only exercise powers within their clearly defined jurisdiction; ambiguity leads to ultra vires acts and conflicts.

Mootness Argument Rejected

The contention that the Napico plebiscite is now moot was rejected based on Tan v. COMELEC, which held that constitutional challenges to a plebiscite’s legality cannot be extinguished by a fait accompli. The Court will not allow an alleged illegal cre
