G.R. No. L-66866, June 18, 1987
Republic of the Philippines vs. Minda de Porkan, et al.

FACTS

The case involves two parcels of land, Lots 1099 and 1546, in Carmen, Davao del Norte. The lots were allocated to Medori de Porkan and Macampon de Porkan, respectively, during the 1937 Tagum Cadastral Survey, based on their family’s possession since the Spanish period. For Lot 1099, Medori filed a free patent application in 1953, later relinquishing her rights to her daughter, Lolita Macatindog, who was issued Free Patent No. 488112 and Original Certificate of Title No. P-9742 in 1971. She later sold a portion to Juan Arangali. For Lot 1546, allocated to the deceased Macampon, Sadin Maraug filed a homestead application in 1953, which was approved. He later transferred his rights to Minda de Porkan, who was issued Homestead Patent No. 135029 and Original Certificate of Title No. P-10095 in 1972. She later sold a portion to Gorgonio Bermudez.
The Republic, through the Director of Lands, filed complaints for cancellation of these patents and titles. The government alleged the lands were part of the public domain, specifically within a zone classified as “Timberland” per a 1921 map, and that a portion was covered by a fishpond permit issued to Viola Azurin in 1966. The trial court dismissed the complaints, a decision affirmed by the Intermediate Appellate Court.

ISSUE

The primary issue is whether the homestead and free patents, and the subsequent certificates of title issued to the private respondents, are valid and indefeasible, or whether they should be cancelled on the grounds that the lands were inalienable timberland or that the patents were issued over areas claimed under a fishpond permit.

RULING

The Supreme Court denied the petition and affirmed the appellate court’s decision, upholding the validity of the patents and titles. The Court’s legal logic rested on two key principles. First, the official issuance of a patent and the consequent grant of a certificate of title operate as a government declaration that the land is alienable and disposable. This official act has the force and effect of formally reclassifying the land, rendering any previous general classification (like the 1921 timberland map) inconclusive and insufficient to defeat the granted title. The patent itself is conclusive evidence of the state’s act of conveyance.
Second, the claim based on Viola Azurin’s fishpond permit failed. The permit was temporary, expiring in 1966, and her subsequent sales application was never approved. She therefore acquired no vested right over the area that could prevail against the perfected and vested rights of the patentees. The Court emphasized that the private respondents’ predecessors-in-interest had possessed the lands since the Spanish era, and the patents were issued after due investigation and compliance with legal requirements. The titles, having become indefeasible one year after issuance, could no longer be impugned on the basis of an expired permit or an old, general land classification map. The state’s solemn act of issuing the patents must be upheld.
