Barangay Boundary Disputes: Why the Sanggunian, Not Courts, Resolves Them First

The Supreme Court recently settled an important question for local governments: who has the authority to resolve a dispute over barangay boundaries? In Barangay Mayamot, Antipolo City v. Antipolo City (G.R. No. 187349, August 17, 2016), the Court ruled that the Regional Trial Court (RTC) does not have original jurisdiction over such disputes. Instead, the sangguniang panlungsod or sangguniang bayan—the local legislative body—must first hear and decide the matter.

This ruling clarifies the proper forum for boundary conflicts and reinforces the principle of local autonomy in the Philippines.

The Dispute: A Resolution That Redrew Boundaries

The case began in Antipolo City, which had sixteen barangays after eight new ones were created by Batas Pambansa Bilang (BP Blg.) 787 to 794 in 1984. To integrate all barangay territories into one official map, the Sangguniang Bayan passed Resolution No. 97-89, which approved boundary delineations prepared by the City Assessor based on a Bureau of Lands Cadastral Survey.

Barangay Mayamot objected. It claimed that the resolution reduced its territory to half its original size, apportioning land to neighboring barangays Sta. Cruz, Bagong Nayon, Cupang, and Mambugan. It argued that the resolution effectively altered its boundaries without the ordinance and plebiscite required by Section 82 of the Local Government Code of 1983 (BP Blg. 337).

Barangay Mayamot filed a petition before the RTC for the nullification of Resolution No. 97-89. The RTC dismissed the case, and the Court of Appeals affirmed. The Supreme Court upheld these dismissals—but on a different ground.

The Issue: Jurisdiction, Not the Resolution's Validity

The Supreme Court framed the issue not as the validity of Resolution No. 97-89, but as a boundary dispute between Barangay Mayamot and its neighbors. The Court explained that jurisdiction is determined by the material allegations of the complaint, not by its caption or designation.

Barangay Mayamot's allegations centered on the alleged inconsistency between its perceived actual territory and the boundaries defined after the consolidation of the cadastral survey and BP Blg. 787 to 794. This, the Court said, is precisely a boundary dispute—a claim by one local government unit over a portion of another's territory.

The Ruling: The Sanggunian Has Original Jurisdiction

The Court applied the Local Government Code of 1991 (Republic Act No. 7160), which was already in effect when Barangay Mayamot filed its case in 1999. Under Section 118, boundary disputes between two or more barangays in the same city or municipality shall be referred for settlement to the sangguniang panlungsod or sangguniang bayan concerned.

The process works as follows:

• The sanggunian must first attempt an amicable settlement.
• If no settlement is reached within sixty (60) days, the sanggunian issues a certification to that effect.
• The sanggunian then formally tries the dispute and decides it within sixty (60) days from the certification.
• Under Section 119, the decision may be appealed to the RTC having jurisdiction over the area in dispute.

The Court cited its earlier rulings in Municipality of Sta. Fe v. Municipality of Aritao and Municipality of Pateros v. Court of Appeals to emphasize that the RTC lost its power to try boundary disputes at the first instance under the 1991 Code. The RTC only steps in on appeal, after the sanggunian has acted.

Because Barangay Mayamot went directly to the RTC, its petition was correctly dismissed for lack of jurisdiction. The Court noted that the defense of lack of jurisdiction over the subject matter may be raised at any time, even on appeal or after final judgment.

Practical Takeaways

• Barangay boundary disputes must first go to the sanggunian. The sangguniang panlungsod or sangguniang bayan has original jurisdiction to hear and decide these cases, not the RTC.
• The RTC acts only on appeal. A party may elevate the sanggunian's decision to the RTC within the time and manner prescribed by the Rules of Court, and the RTC must decide the appeal within one year.
• The caption of a case does not control. Courts look at the substance of the allegations to determine the true nature of the action and which forum has jurisdiction.
• The law in force at the time of filing governs jurisdiction. Even if an earlier law applied when the challenged resolution was passed, the statute in effect when the action is commenced determines the court's jurisdiction.
• Local autonomy is reinforced. The Code gives local legislative bodies a primary role in resolving territorial conflicts among their own barangays, with courts serving only as appellate review.
