G.R. No. 170207. April 19, 2010.
VICENTE CAWIS (substituted by his son, EMILIO CAWIS), et al., Petitioners, vs. HON. ANTONIO CERILLES, in his capacity as the DENR Secretary, et al., Respondents.

FACTS

Petitioners claimed to be actual occupants of Lot No. 47 within the Holy Ghost Hill Subdivision in Baguio City. The sales patent for the lot was approved for Jose V. Andrada in 1957 under the Public Land Act, and an Original Certificate of Title (OCT) was eventually issued to respondent Ma. Edeliza Peralta after she purchased it from Andrada in 1987. Petitioners protested, invoking Republic Act (R.A.) No. 6099, which provided for the sale of lands in the subdivision to actual occupants. The Bureau of Lands denied their protest in 1987, a decision which became final due to petitioners’ failure to appeal.
In 1998, petitioners filed a complaint before the Regional Trial Court seeking annulment of the sales patent and title, alleging fraud and misrepresentation. They argued that Peralta and her predecessor failed to construct the required residential improvements on the lot, a condition for the patent, and that R.A. No. 6099 effectively revoked Andrada’s patent in their favor. The trial court dismissed the complaint, ruling that an action for reversion based on fraud can only be initiated by the government through the Office of the Solicitor General (OSG). The Court of Appeals affirmed this dismissal.

ISSUE

The primary issue is whether the petitioners, as alleged actual occupants, have the legal standing to file a direct action for the annulment of the sales patent and certificate of title issued over the subject lot.

RULING

The Supreme Court denied the petition and upheld the dismissal. The Court ruled that petitioners lack the requisite legal standing to institute the action for annulment. Under Section 101 of the Public Land Act (Commonwealth Act No. 141), all actions for the reversion of lands of the public domain to the government must be instituted by the Solicitor General or his representative in the name of the Republic of the Philippines. An action for annulment of a patent and certificate of title on the ground of fraud in their issuance is essentially a reversion proceeding. Such an action impugns the State’s original act of granting the land, and thus, only the State can question the validity of its own grant.
The Court clarified that this rule is without prejudice to a private individual’s right to bring an action for reconveyance, provided it is based on a claim of ownership and does not seek to nullify the State’s grant. Here, petitioners’ suit was a direct attack on the validity of the patent and title, which is a reversion claim reserved to the State. Their reliance on R.A. No. 6099 did not confer a vested right or automatic ownership; it merely granted a privilege to apply for a sales patent, which they did not timely pursue. Consequently, they are not the real parties-in-interest to file the annulment case.
