G.R. No. 112115 March 9, 2001
Republic of the Philippines, petitioner, vs. Court of Appeals and Ceferino Paredes, Jr., respondent.

FACTS

Private respondent Ceferino Paredes, Jr. purchased a parcel of land in 1974. In 1976, he filed an application for a free patent over a larger, adjacent area, which was approved, leading to the issuance of Free Patent No. (X-8) 1253 and Original Certificate of Title No. P-8379. He subsequently constructed his house on the land. In 1984, the Sangguniang Bayan of San Francisco, Agusan del Sur, adopted resolutions asserting that the lot was part of a public land reservation designated as a school site long before the title was issued. The municipality questioned the posting of Paredes’s application and requested the Solicitor General to initiate action. Consequently, the Republic filed a complaint for the cancellation of the patent and title and for reversion of the land to the public domain. The Regional Trial Court ruled in favor of the Republic, declaring the patent and title null and void.

ISSUE

The core issue is whether the grant of a free patent and the subsequent issuance of a certificate of title over the subject land were valid, considering the land was allegedly part of a withdrawn public land reservation and the applicant may have committed fraud.

RULING

The Supreme Court granted the petition, reinstating the trial court’s decision. The legal logic centered on the violation of a specific legal prohibition and the presence of fraud. First, the Court found that Proclamation No. 336, issued in 1952, withdrew the land from settlement, permitting its acquisition only through homestead or purchase. Paredes acquired the land via a free patent, a mode explicitly not allowed under the proclamation. This fundamental legal infirmity alone was sufficient to nullify the title. Second, the Court agreed with the trial court’s finding of misrepresentation. Paredes falsely declared in his application that the land was not within any government reservation. Evidence, including a certification from the Bureau of Lands, conclusively established that the lot was indeed part of the San Francisco Town Site Reservation, which had been set aside for a school site. This constituted a fraudulent misrepresentation that vitiated the patent. The Court also rejected the defense of estoppel, holding that the doctrine does not apply against the state in acts involving public lands and reversion. The government retains the perpetual authority to investigate fraud in the acquisition of titles to ensure public land is disposed of in accordance with law. Therefore, the patent and title were correctly declared void, and the land reverted to the public domain.
