G.R. No. L-49749, June 18, 1987
Andrea Sangalang vs. Rev. Balbino Caparas, Development Bank of the Philippines, and Register of Deeds of Rizal

FACTS

The property, originally owned by Ramon Florentino and mortgaged to the Development Bank of the Philippines (DBP), was sold by Florentino to Rev. Balbino Caparas via a Deed of Sale with Assumption of Mortgage in 1954. After DBP foreclosed on the property in 1960, both Florentino and Caparas sought to redeem it. During this period, Florentino also executed a Deed of Absolute Sale in favor of Andrea Sangalang in January 1961, which she promptly registered. Caparas had registered his earlier deed only in May 1961. With multiple claims, Caparas filed a suit for Specific Performance with Consignation against DBP (Civil Case No. 6685) to determine the better right to redeem. Sangalang intervened. The trial court and the Court of Appeals ruled in favor of Caparas, finding Sangalang was not a purchaser in good faith and that her knowledge of the prior sale to Caparas was equivalent to registration, negating any priority from her earlier registration.
Subsequently, Sangalang filed the present Complaint for Quieting of Title, seeking to cancel Caparas’s title derived from his redemption. The Court of First Instance dismissed her complaint on the ground of res judicata, holding that the issues had been conclusively settled in the prior case (Civil Case No. 6685).

ISSUE

Whether the principle of res judicata bars Sangalang’s action for quieting of title.

RULING

Yes, res judicata applies. The Supreme Court affirmed the dismissal. For res judicata to exist, four requisites must concur: (1) a final former judgment; (2) a court of competent jurisdiction rendered it; (3) it is a judgment on the merits; and (4) there is identity of parties, subject matter, and causes of action between the first and second cases. All these elements are present. The decision in Civil Case No. 6685 was a final judgment on the merits by a competent court. The parties—Sangalang and Caparas—are identical. The subject matter is the same parcel of land. The cause of action is fundamentally identical: the determination of ownership and the better right to the property arising from the conflicting sales and redemption rights.
The Court emphasized that the prior case conclusively adjudicated Sangalang’s status as a purchaser in bad faith. Her knowledge of Caparas’s prior unregistered sale was deemed equivalent to registration, defeating her claim of being a registrant in good faith entitled to priority under the Torrens system. This finding is binding. The present action for quieting of title, though framed differently, essentially seeks to relitigate the issue of ownership already settled against her. The Court also noted that Caparas, as a vendee a retro who validly redeemed the property from DBP pursuant to the final judgment, acquired clear title. Therefore, Sangalang cannot now seek to cancel that title. The defense of res judicata was properly invoked to prevent endless litigation over a matter already definitively resolved.
