THE AI-ASSISTED CRITIQUE
The Court’s reliance on mathematical calculation to resolve the boundary dispute demonstrates a rigorous application of Res Ipsa Loquitur, treating the physical dimensions as self-evident facts that override conflicting documentary descriptions. By establishing that the area described in the petitioner’s titles (over 4,000 or 3,000 square meters) could not physically fit within the city’s claimed strip (maximum 1,835.4 square meters), the analysis conclusively proves the land must extend into the plaza. This quantitative method effectively sidesteps ambiguities in the historical Spanish-language deeds, providing an objective benchmark that makes the city’s prescription claim untenable given the proven encroachment.

The decision implicitly upholds the Torrens system‘s principle that registration clarifies title, but it interestingly prioritizes extrinsic physical evidence over the muniments of title themselves in interpreting their scope. The Court notes discrepancies between the exhibits and the survey plan but dismisses them as either favoring the city or being “substantially negligible,” thereby accepting the plan’s authority. This approach suggests that when documentary descriptions are ambiguous or conflicting, adverse possession claims by a municipality must be defeated by clear, demonstrable encroachment, placing a high burden on the public entity to prove its possession excluded the titled area.

Ultimately, the ruling protects property rights derived from a royal grant against municipal encroachment by meticulously correlating historical descriptions with present-day topography. The Court’s step-by-step geometric reasoning leaves no room for the city’s assertion that a long-standing fence constituted a recognized boundary, as the math proves the fence could not have enclosed the granted parcel. This sets a precedent that physical impossibility, when proven through survey evidence, can trump even long-standing possession claims, ensuring that land registration adjudication remains anchored in verifiable spatial reality rather than contested historical narratives.
