G.R. No. 96302 November 29, 1991
AMBROCIO MUYCO, petitioner, vs. THE HONORABLE COURT OF APPEALS and SERGIO SAGA, respondents.

FACTS

Eugenio Saga obtained a homestead patent over a portion of Lot No. 5164 in 1939. The Bureau of Lands later subdivided this into Lots 5956 and 6331. In 1952, Eugenio sold his rights to his son, Sergio Saga, who subsequently filed a homestead application for Lot 5956 and was issued an Original Certificate of Title (OCT) in 1954. Meanwhile, Leon Tolabing had filed a homestead application for the same Lot 5956 in 1946, which was approved. Tolabing sold his rights to Ambrocio Muyco in 1955, who then filed his own application. Investigations by the Public Land Inspector found that Sergio Saga was actually occupying Lot 6331, not Lot 5956, and recommended correcting the title, but these findings were contested.
Sergio Saga filed an action for recovery of possession against Muyco, relying on his OCT. The trial court ruled in favor of Saga, holding the title indefeasible. The Court of Appeals affirmed this decision, prompting Muyco’s petition to the Supreme Court, arguing error in the title issuance and asserting Tolabing’s vested right.

ISSUE

The core issue is whether the OCT issued to Sergio Saga over Lot 5956 is indefeasible, thereby precluding Muyco’s claim derived from Tolabing’s earlier application.

RULING

The Supreme Court denied the petition and affirmed the appellate court’s decision. The legal logic rests on the principle of indefeasibility of a certificate of title issued under a homestead patent. The Court held that Eugenio Saga acquired a vested right over the homestead land upon the grant of his patent in 1939. This right was validly transferred to his son, Sergio. Consequently, the subsequent approval of Leon Tolabing’s application for the same land was erroneous, as the land was already disposed of by the state.
Crucially, the OCT issued to Sergio Saga in 1954 became indefeasible and incontrovertible one year from its issuance, pursuant to settled jurisprudence. Any alleged error in the issuance or identification of the lot number should have been challenged within that one-year period. The investigations and recommendations by land officials after the title’s issuance could not override the titling decree’s conclusiveness. Therefore, Sergio Saga’s title prevails, and Muyco’s claim, based on a denied application, cannot be sustained. The proper remedy for such a factual error, if it existed, was reconveyance, but this action was effectively barred by the failure to contest the title within the statutory period.
