Municipal Boundaries Law Prevails Over Inconsistent Interpretation

The Supreme Court has settled a long-running boundary dispute between two municipalities in Ilocos Norte, ruling that the law creating a municipality fixes its boundaries and that any alteration not in accordance with that law is an amendment that only Congress can make. The case of Municipality of Nueva Era v. Municipality of Marcos (G.R. No. 169435, February 27, 2008) clarifies how courts should interpret conflicting provisions in a municipal charter and reaffirms the limits on local government units' power to claim territory.

The Dispute

The Municipality of Marcos was created in 1963 under Republic Act No. 3753, which separated seven barrios from the Municipality of Dingras and constituted them into a new municipality. The law named only Dingras as the source of Marcos's territory.

However, the same law described Marcos's eastern boundary as "the Ilocos Norte-Mt. Province boundary." Because the Municipality of Nueva Era lay between Marcos and that provincial boundary, Marcos claimed that this description entitled it to a 15,400-hectare portion of Nueva Era's Barangay Sto. Niño.

Marcos waited nearly 30 years before asserting this claim, filing it only in 1993 before the Sangguniang Panlalawigan of Ilocos Norte.

The Proceedings Below

The Sangguniang Panlalawigan dismissed Marcos's claim, ruling that since R.A. No. 3753 expressly named only Dingras barrios as composing Marcos, no part of Nueva Era was included. The Regional Trial Court affirmed this decision, noting that the legislative intent, as shown in the bill's explanatory note, was to create Marcos solely from Dingras territory.

The Court of Appeals reversed in part, extending Marcos's eastern boundary to the Ilocos Norte-Kalinga-Apayao boundary and thereby allocating a portion of Nueva Era's territory to Marcos. The appellate court reasoned that the law's boundary description was explicit and that stopping short of it would amount to amending the law.

The Supreme Court's Ruling

The Supreme Court reversed the Court of Appeals and reinstated the RTC decision, ruling in favor of Nueva Era.

First, the Court addressed the procedural issue. The Court of Appeals had treated Marcos's appeal as a petition for certiorari, believing that Section 119 of the Local Government Code made the RTC the final arbiter. The Supreme Court held this was error: Batas Pambansa Blg. 129, as amended by R.A. No. 7902, vests appellate jurisdiction in the Court of Appeals over all final judgments of RTCs, including those rendered in the exercise of appellate jurisdiction.

Second, on the merits, the Court applied the maxim expressio unius est exclusio alterius — the mention of one thing implies the exclusion of another. Since R.A. No. 3753 enumerated only Dingras barrios as composing Marcos, Nueva Era's territory was excluded by implication.

The Court also applied the rule of casus omissus pro omisso habendus est: a thing omitted from an enumeration must be held to have been omitted intentionally. The explanatory note of the bill, which mentioned only Dingras as the mother municipality, supported this conclusion.

The Court rejected Marcos's argument that the boundary description should prevail over the enumeration of source barrios. The boundary description, the Court held, was merely descriptive of the listed Dingras barrios as a compact and contiguous territory. Where a literal reading would lead to absurdity, the law must be given a reasonable interpretation consistent with legislative intent.

The Court also addressed Nueva Era's argument that a plebiscite was required. It noted that at the time Marcos was created in 1963, no plebiscite requirement existed. The constitutional plebiscite requirement is prospective in application and does not affect municipalities created before its effectivity.

Practical Takeaways

• A municipality's charter controls its boundaries. The law creating a local government unit is the primary reference for determining its territorial jurisdiction.

• Express enumeration excludes what is not mentioned. When a law names specific source territories, areas not named are deemed excluded, even if a boundary description appears to suggest otherwise.

• Only Congress may alter municipal boundaries. Local government units and even courts cannot effectively amend a charter by interpretation. Any substantial alteration requires legislative action.

• Legislative intent resolves ambiguity. Where a charter provision is ambiguous, courts may look to explanatory notes and the statute's overall purpose to ascertain intent.

• Constitutional plebiscite requirements apply prospectively. Municipalities created before the 1973 and 1987 Constitutions took effect are not invalidated by the absence of a plebiscite.
