G.R. No. 149097; October 18, 2004
MACARIO S. TANCUNTIAN, as substituted by his heir, FRUCTUOSA TANCUNTIAN-ABRENICA and CRISTINA D. CAYANG, petitioners, vs. CECILIO VICENTE T. GEMPESAW, et al., and COURT OF APPEALS, respondents.

FACTS

Petitioners, claiming to be the beneficial owners of Lots 968 and 953 in Davao City covered by Original Certificates of Title (OCTs) issued in 1976, filed an action for cancellation of title and damages against respondents. They alleged that respondents fraudulently secured free patents and subsequent titles over portions of the same lots from the Bureau of Lands in the 1980s and 1990s, despite the land already being privately owned and titled. Petitioners sought the nullification of respondents’ titles, reconveyance, and damages, asserting their action was one to quiet title over their private property.
The Regional Trial Court (RTC) initially dismissed the complaint motu proprio, ruling that only the Republic, through the Solicitor General, could file a case for cancellation of title on grounds of fraud in the issuance of a free patent. Upon reconsideration, a different RTC judge reinstated the complaint. However, the Court of Appeals later affirmed the original dismissal, holding that petitioners lacked the legal personality to sue. The CA ruled that an action for cancellation of a free patent title, even if the land is allegedly private, is a reversion suit that can only be prosecuted by the State.

ISSUE

Do the petitioners, as registered owners of the land, possess the legal personality to institute an action for the cancellation of titles derived from allegedly void free patents issued over the same property?

RULING

Yes. The Supreme Court reversed the Court of Appeals and reinstated the complaint for trial. The Court clarified the nature of the action and the standing of the petitioners. An action for reversion under the Public Land Act, which must be filed by the Solicitor General, applies only when the subject land is part of the public domain. Here, petitioners anchored their case on the allegation that the land was already private, covered by their own OCTs issued prior to the respondents’ free patents. Consequently, their suit was not for reversion but essentially an action to quiet title—a suit to remove a cloud upon their ownership by seeking the cancellation of instruments (the free patents and subsequent titles) that were allegedly fraudulently issued and thus void ab initio.
The Court held that petitioners are the real parties-in-interest under the Rules of Civil Procedure, as they stand to be benefited or injured by the judgment. As the registered claimants, they have the legal personality to protect their ownership and seek judicial recourse to nullify titles that unlawfully overlap with their own. The jurisdiction of the Director of Lands is limited to public lands; it does not extend to lands already privately owned. A free patent issued over land that has ceased to be public confers no valid title against the true registered owner. Therefore, the registered owner has the right to directly assail such a patent. The case was remanded to the RTC for trial on the merits to allow petitioners to prove their ownership and the nullity of the respondents’ titles.
