Boundary Disputes in the Philippines: Resolving Territorial Conflicts Between LGUs

The decades-long territorial dispute between the cities of Makati and Taguig reached its conclusion before the Supreme Court in 2021. The case involved not only the physical boundaries between two neighboring local government units (LGUs) but also important procedural questions about how courts should handle appeals when a party has committed forum shopping. The decision provides valuable guidance for LGUs and lawyers dealing with territorial conflicts.

The Origins of the Dispute

The conflict centered on the Enlisted Men's Barangays (EMBOs) and Fort Bonifacio, an area that both cities claimed as part of their territory. Taguig argued that these areas had historically been within its jurisdiction, tracing its existence as a pueblo during the Spanish colonial period. Makati, on the other hand, claimed that the disputed areas fell within its territory based on its own historical records and cadastral surveys.

The case began in 1993 when Taguig filed a complaint before the Regional Trial Court of Pasig, seeking judicial confirmation of its territorial boundaries and challenging the constitutionality of Presidential Proclamations that placed the disputed areas under Makati's jurisdiction.

The Constitutional Requirement

A key issue in the case was whether Presidential Proclamation Nos. 2475 and 518 were constitutional. Taguig argued that these proclamations altered its boundaries without the plebiscite required by Article X, Section 10 of the 1987 Constitution. This provision requires that any change in the territorial boundaries of a local government unit must be approved by a majority of the votes cast in a plebiscite held in the affected areas.

The Supreme Court's ruling in the earlier case involving these parties (City of Taguig v. City of Makati, G.R. No. 208393) found Makati guilty of forum shopping for pursuing simultaneous remedies. However, the Court chose to impose fines on Makati's lawyers rather than dismiss the appeal outright.

The Forum Shopping Issue

When the Court of Appeals later dismissed Makati's appeal based on the forum shopping finding, the Supreme Court corrected this action. The Court explained that the dispositive portion, or fallo, of its earlier decision had limited the sanction to a fine. The body of the decision may discuss forum shopping, but the dispositive portion controls what remedies are actually imposed.

This ruling reaffirms the established principle that when there is a conflict between the dispositive portion and the body of a decision, the dispositive portion prevails. The Court cited the case of BBB v. People in reiterating this rule, along with earlier jurisprudence such as Florentino v. Rivera and Republic v. Nolasco.

The Merits of the Territorial Claim

Despite correcting the Court of Appeals on the forum shopping issue, the Supreme Court ultimately ruled in favor of Taguig on the merits. The Court found that Taguig was able to prove its claim over the disputed areas by preponderance of evidence. This included historical records, cadastral surveys, and other documentary evidence showing that the disputed territories formed part of Taguig's jurisdiction.

Practical Takeaways

• LGUs must respect the constitutional requirement for a plebiscite before any boundary alteration can take effect. Presidential proclamations cannot override this requirement.
• When a court decision contains both a finding and a specific penalty, the dispositive portion determines the actual remedy imposed. Parties cannot use statements in the body of the decision to expand the sanctions beyond what the fallo provides.
• Forum shopping is a serious violation that can result in sanctions, including fines against lawyers. However, the specific consequences depend on what the court actually orders in its dispositive portion.
• Territorial disputes between LGUs often require examining historical records, cadastral surveys, and official maps. Parties should gather comprehensive documentary evidence to support their claims.
• Boundary conflicts can take decades to resolve. Both LGUs and their lawyers should be prepared for lengthy litigation and should avoid procedural missteps that could complicate their cases.
