Case Digest (G.R. No. 178467)
Expanded Legal Reasoning Model

Facts:

  • Creation of Municipalities
    • Nueva Era was organized by Executive Order No. 66 (Sept. 30, 1916), consolidating the rancherias of Bugayong, Cabittaoran, Garnaden, Padpadon, Padsan, Paorpatoc, Tibangran and Uguis into a township.
    • Marcos was created by Republic Act No. 3753 (June 22, 1963), separating the barrios of Capariaan, Biding, Escoda, Culao, Alabaan, Ragas and Agunit from Dingras, Ilocos Norte.
  • Boundary Descriptions and Administrative Changes
    • Section 1, RA 3753 describes Marcos’s boundaries: northwest by Biding–Rangay; northeast by Burnay River; east by Ilocos Norte–Mt. Province boundary; south by Padsan River; west and southwest by Dingras–Batac line.
    • Mt. Province later subdivided (RA 4695, 1966; RA 7878, 1995) into Benguet, Mountain Province, Ifugao, Kalinga and Apayao, making the “Ilocos Norte–Mt. Province” boundary effectively the Ilocos Norte–Apayao line.
  • Emergence of the Boundary Dispute
    • In 1993, Marcos’s Sangguniang Bayan passed Resolution No. 93-015 claiming that to reach its statutory eastern boundary it must include central and northern portions of Nueva Era (Barangay Sto. Niño), totaling about 15,400 ha.
    • Nueva Era countered by Resolution No. 1, Series 1993, invoking ancestral domain of the Tinguians and the principle expressio unius est exclusio alterius, noting RA 3753 named only Dingras barrios.
  • Administrative and Judicial Proceedings
    • Sangguniang Panlalawigan of Ilocos Norte dismissed Marcos’s petition (Mar. 29, 2000), declaring the disputed area part of Nueva Era.
    • RTC Branch 12, Laoag City affirmed the SP decision (Mar. 19, 2001).
    • CA reversed in part (June 6, 2005), extending Marcos’s eastern boundary to the Ilocos Norte–Kalinga-Apayao line but denying the claim over the isolated northern portion. The CA treated the petition as certiorari for lack of further appeal under the Local Government Code.
    • Nueva Era filed a Rule 45 petition for certiorari to the Supreme Court, challenging CA’s jurisdiction, mode of appeal, and boundary ruling.

Issues:

  • Jurisdiction and Mode of Appeal
    • Whether the Court of Appeals could entertain a petition for review of an RTC decision on a municipal boundary dispute, or should the remedy be limited to appeal to the RTC under the Local Government Code.
    • Whether the CA gravely abused its discretion by treating Marcos’s Rule 42 petition for review as a certiorari under Rule 65.
  • Eastern Boundary of Marcos
    • Whether RA 3753’s description “on the East, by the Ilocos Norte–Mt. Province boundary” extends Marcos’s territory over parts of Nueva Era (Barangay Sto. Niño).
    • Whether Marcos’s statutory eastern boundary may be interpreted to traverse territory not expressly enumerated in the law creating it.
