THE AI-ASSISTED CRITIQUE
The Court’s reliance on secondary evidence to establish the existence and content of a lost “composition title” is a critical point of legal vulnerability. While the destruction of archives and Fontanet’s house provides a factual basis for the non-production of the original document, the ruling essentially permits the reconstruction of a sovereign grant—a transaction involving public domain—through oral testimony and a private deed of sale (Exhibit B). This sets a precarious precedent for proving ownership of significant land grants, as it lowers the evidentiary bar for what constitutes satisfactory proof of a state concession. The legal doctrine of “best evidence rule” is substantially relaxed here based on circumstances of loss, but the decision risks conflating proof of possession with proof of a valid, grant-derived title, which are distinct under property law.

The analysis of prescription as an alternative basis for ownership is legally insufficient. The opinion notes the petitioner’s claim of continuous, peaceful, and adverse possession by himself and his predecessors but fails to engage in the rigorous application of the required elements for acquisitive prescription. Crucially, there is no examination of whether the possession was in the concept of an owner (“en concepto de dueño”) for the statutory period against the State, which is the true opponent here. The withdrawal of private oppositions by residents and the municipality is procedurally irrelevant to the core issue of state ownership and the inalienability of public domain absent a proper grant. By not squarely addressing whether the possession was adverse to the Government, the Court sidesteps the fundamental public land law principle that no length of possession by a private individual can ripen into ownership unless the land is already alienable or disposable.

The procedural handling of the government’s opposition through the Office of the Solicitor-General is treated perfunctorily, missing a deeper constitutional duty. The State’s interest in conservation of natural resources and protection of public dominion over islands is paramount. The Court’s acceptance of the petitioner’s narrative, based largely on uncorroborated testimonies about events decades prior, without demanding stronger corroborative evidence for a claim over an entire island, reflects an undue deference to private claims over public assets. The legal maxim “regalia doctrine” underpins that all lands of the public domain belong to the State, and the burden to overcome this presumption with clear, convincing evidence is exceptionally high. This decision, by allowing inscription based on a chain of transactions rooted in an unproven state grant, potentially weakens the doctrine of jura regalia and could encourage speculative claims based on lost documentary evidence.
