THE AI-ASSISTED CRITIQUE
The court’s reliance on the doctrine of Jura Regalia is central, as it presumes all lands belong to the State unless proven otherwise, placing a stringent burden of proof on private claimants. The appellants’ failure to perfect title under Spanish decrees, such as the Royal Decree of June 25, 1880 or the Royal Decree of February 13, 1894, is fatal, as the court correctly notes that mere possession without legalization under those regimes caused the land to revert to the public domain. This aligns with precedents like Fuster vs. Director of Lands, which emphasize that the State’s offer of gratuitous title through possessory information proceedings was a conditional opportunity; non-compliance extinguishes any inchoate right, reinforcing that adverse possession alone cannot overcome the regalian doctrine without statutory compliance.

The rejection of the constitutional ex post facto argument is legally sound, as the prohibition applies solely to criminal penalties, not to the retrospective alteration of civil property rights under public land laws. The court properly distinguishes that no vested right accrued under Act No. 926 , since the appellants never filed an application for confirmation during its efficacy, and the repeal by Act No. 2874 did not impair a substantive claim but merely adjusted procedural avenues. This highlights a key principle: statutes governing public lands are remedial and do not create entitlements until all statutory conditions are met, including timely judicial assertion.

Ultimately, the court’s insistence on open, continuous, exclusive, and notorious possession from July 26, 1894, is consistent with the presumptive grant theory, but the evidence here failed to meet that high standard. The appellants’ claim of possession since 1874 was undermined by lack of documentary titling and failure to engage with Spanish land regularization processes. The decision underscores that judicial confirmation under Acts 926 or 2874 requires not just factual possession but also adherence to evolving statutory frameworks, ensuring public lands are reserved for state purposes like the agricultural school site here.
