Facts

March 22, 1902

Sesinando Leyva, the applicants’ earliest known predecessor-in-interest, had the land in Antipolo, Rizal, surveyed in his name.

July 26, 1904

Executive Order No. 33 established the Marikina Watershed Reservation. By then, Leyva had been in possession for only two years.

April 25, 1985

Edna T. Collado applied to register the land, about 120 hectares, and co-applicants later joined her. They alleged occupation since time immemorial, tax declarations and payment of real estate taxes. The technical description attached to the application, signed by an officer of the Bureau of Lands, stated: “[t]his survey is inside IN-12 Mariquina Watershed.”

1988–1991

The Republic, through the Solicitor General, and the Municipality of Antipolo had filed oppositions. The Solicitor General later submitted a March 2, 1988 report of the Administrator of the National Land Titles and Deeds Registration Administration confirming that the lot formed part of the watershed. At the January 1991 hearings, the oppositors presented no evidence, and the court considered the case submitted on the applicants’ evidence.

January 30, 1991

The Regional Trial Court of Antipolo, Branch 71, sitting as a land registration court, confirmed the applicants’ imperfect title, and in May 1991 it ordered the issuance of the decree.

1991–1992

On August 6, 1991, the Solicitor General filed a petition for annulment of judgment in the Court of Appeals, and holders of DENR certificates of stewardship over the area intervened. On June 22, 1992, the Court of Appeals declared the trial court’s decision null and void.

Issue

Could possession of land inside the Marikina Watershed Reservation ripen into private ownership, and could the trial court’s decision confirming the applicants’ title stand?

Ruling

No. The Court denied the petition and affirmed the Court of Appeals. Any title to the lot is void ab initio, because the land registration court never acquired jurisdiction over it.

From 1904, the lot was inalienable public land. When the application was filed, it had been reserved as a watershed for 81 years, and Leyva’s two years before 1904 were not enough. Once land is included in a watershed reservation established by executive proclamation, it is presumed to remain part of the reservation until clear and convincing evidence of declassification is shown, and declassification requires a positive act of the Executive. The applicants’ claim of reclassification was contradicted by documents the Solicitor General submitted. Even if a 1974 townsite proclamation had excluded the lot, the applicants would have had only eleven years of possession by 1985, and according to the DENR Secretary, a 1977 proclamation reverted the area to the watershed. Because the land registration court never acquired jurisdiction over the lot, the alleged procedural defects of the annulment petition were immaterial, and the Court added that “environmental consequences in this case override concerns over technicalities and rules of procedure.” It also upheld the intervention of the stewardship holders, noting that the case had “already claimed at least five lives.”

“It is axiomatic that the possession of forest lands or other inalienable public lands cannot ripen into private ownership.”
Collado vs. Court of Appeals, G.R. No. 107764, October 4, 2002

Doctrine

Under the Regalian doctrine, “all lands not otherwise appearing to be clearly within private ownership are presumed to belong to the State.” Land included in a watershed reservation established by executive proclamation is presumed to remain part of it “until clear and convincing evidence of subsequent declassification is shown,” and declassification takes a positive act of the Executive, such as an official proclamation. Until then, possession, however long, does not ripen into ownership, and a land registration court acquires no jurisdiction to confirm title to the land.

Compare: native title

In Cariño vs. Insular Government, 212 U.S. 449, February 23, 1909, the claimant won because land held under a claim of private ownership as far back as testimony or memory goes was presumed “never to have been public land.” Collado does not discuss Cariño; its applicants claimed possession under the Public Land Act.

Bar tip

Classification comes before possession. If the land is inside a watershed or other reservation, no length of possession will ripen into ownership. A decision confirming title to such land is void for lack of jurisdiction, even if the applicants claim it has become final.
