G.R. No. L-50107 November 14, 1984
Exequiel Lising and Loreta Viola, petitioners, vs. Honorable Andres Plan, Mamerto Licuanan, Vicente Garcia and Estrella Magat, respondents.

FACTS

Petitioner-spouses Exequiel Lising and Loreta Viola, original homesteaders of a 23-hectare lot, sold the entire property to respondent Mamerto Licuanan. The Lising spouses later sued to repurchase the homestead under the Public Land Act in Civil Case No. II-428. The trial court upheld their right to repurchase in a 1964 order that became final. Licuanan subsequently filed a separate suit to quiet title (Civil Case No. II-765), which the trial court decided in his favor, but the Court of Appeals reversed this in 1975, reinstating the Lising spouses’ repurchase right. Meanwhile, during the pendency of these cases, Licuanan sold the property to respondent spouses Vicente Garcia and Estrella Magat. In a third case filed by the Garcias to recover a portion of the lot from a prior claimant, the courts declared the Garcias as purchasers in bad faith. The Lising spouses then moved for execution of the final judgment in the repurchase case. The respondent judge issued the writ but excluded the Garcias, ruling they were not parties to the original suit and needed a separate action to assert their defenses.

ISSUE

Whether a writ of execution from a final judgment recognizing a right to repurchase a homestead can be enforced against subsequent purchasers who were not formal parties to the original suit but were declared in bad faith in a related case.

RULING

Yes, execution may be enforced against the Garcias. The core legal logic is that a final judgment in an action for repurchase under the Public Land Act binds not only the parties but also their successors-in-interest. The Garcias are successors-in-interest to Licuanan, the original vendee in the repurchase case. Crucially, their status as purchasers in bad faith was conclusively established in a separate case (the Garcia-Aquino case), where the courts found they bought the property with knowledge of the pending litigation over the repurchase right. This prior adjudication renders a separate civil action to determine their rights unnecessary. The law does not require such redundant proceedings. Furthermore, having purchased with notice of the lis pendens (later cancelled prematurely during appeal) and the ongoing suits, the Garcias had the opportunity to intervene to protect their interests. Their failure to do so means they are bound by the outcome of the litigation. Therefore, they cannot now claim a right to a separate hearing to re-litigate issues already settled by final judgments concerning the very property they acquired. The writ of execution must include them to give full effect to the homesteaders’ vested right of repurchase.
