G.R. No. 131277 February 2, 1999
Spouses FRANCISCO and ANGELA C. TANKIKO and Spouses ISAIAS and ANITA E. VALDEHUEZA, petitioners, vs. JUSTINIANO CEZAR, et al., respondents.

FACTS

Respondents are actual occupants of portions of Lot No. 3714, having resided there since as early as 1965. They are miscellaneous sales patent applicants for their respective occupied areas and have been paying real property taxes. The lot was originally titled under Original Certificate of Title (OCT) No. O-740 in the name of Patricio Salcedo, issued in 1977 pursuant to a 1941 cadastral court decision. Petitioners derived their titles from subsequent purchases from Salcedo’s heirs. Respondents filed an action for reconveyance with damages before the Regional Trial Court (RTC), contesting the validity of the petitioners’ titles. They alleged that the 1941 decision adjudicating the lot to Salcedo was spurious, presenting evidence that a 1940 cadastral decision had declared Lot No. 3714 as public land.
The RTC dismissed the complaint, declaring petitioners as the rightful owners and ordering respondents to vacate. The Court of Appeals (CA) reversed the RTC. The CA set aside the RTC decision, allowed respondents to remain in possession pending administrative proceedings for cancellation of title and a potential reversion action by the State, and ordered the annotation of a notice of lis pendens on the titles. Petitioners sought review by the Supreme Court.

ISSUE

Whether the respondents, as mere sales patent applicants, have the legal standing or personality to file an action for reconveyance of the subject property.

RULING

No. The Supreme Court granted the petition, reversed the CA decision, and reinstated the RTC’s dismissal of the complaint. The Court held that respondents are not the real parties-in-interest required under the Rules of Court. A real party-in-interest is one who stands to be benefited or injured by the judgment. Here, the respondents are merely applicants for sales patents over portions of land they claim as public domain. They have not yet acquired any vested right, title, or interest in the property; their applications only give them an inchoate right that does not equate to ownership.
The Court emphasized that an action for reconveyance based on an implied or constructive trust presupposes that the plaintiff is the true owner of the property. Since the respondents are not owners, they lack the personality to sue. Furthermore, if the property is indeed public land erroneately titled to a private individual, the proper action is for reversion, which can only be instituted by the Solicitor General in the name of the Republic of the Philippines. The Court explicitly ruled that equity cannot be invoked to grant them standing, as equity may only supplement, not supplant, the law. The absence of a legal right cannot be cured by equitable considerations. The dismissal of the complaint was thus proper for lack of a cause of action.
