G.R. No. 179549 ; June 29, 2010
LIRIO A. DEANON, represented by Attorney-in-Fact JOCELYN D. ASOR, Petitioner, vs. MARFELINA C. MAG-ABO, Respondent.

FACTS

The case involves a dispute over possession of a 74-square-meter lot in Pasig City, originally part of a larger property under the government’s Community Mortgage Program. Petitioner Lirio Deanon based her claim on a Waiver of Rights executed by Ma. Imelda Eloisa Galvan on July 28, 2003, and a subsequent Lease/Purchase Agreement with the NAPICO Homeowners Association XIII, Inc. dated January 13, 2004. Deanon alleged that respondent Marfelina Mag-abo was merely occupying the property as a garage without permission. Upon acquiring rights from Galvan, Deanon sent Mag-abo a notice to vacate, which was refused, prompting the filing of an unlawful detainer complaint.
Respondent Mag-abo asserted a superior claim, tracing her right to a sheriff’s auction sale. The rights of the original claimants, spouses Dominador and Ma. Imelda Eloisa Galvan, over the subject property were levied upon to satisfy a civil indemnity from a criminal case. At the public auction on February 28, 1998, Ruth Cabrera purchased these rights. Cabrera subsequently transferred her rights to Mag-abo via a Deed of Transfer and Assignment dated February 23, 2001. Mag-abo argued that this judicial sale extinguished the Galvans’ rights long before Galvan’s waiver to Deanon in 2003.

ISSUE

The core issue is who between the petitioner and the respondent has a better right of possession over the disputed property, which determines the outcome of the unlawful detainer action.

RULING

The Supreme Court ruled in favor of respondent Mag-abo, affirming the decisions of the lower courts. The legal logic hinges on the effect of a judicial execution sale. The Court emphasized that a levy and execution sale effectively divest the judgment obligor (in this case, the Galvan spouses) of all rights to the property as of the time of the levy. The purchaser at the auction sale, Ruth Cabrera, was substituted to all the rights, title, and interest of the Galvans upon the expiration of the redemption period.
Consequently, when Ma. Imelda Eloisa Galvan executed a Waiver of Rights in favor of petitioner Deanon in July 2003, she no longer possessed any transferable rights over the property. Her rights had already been extinguished by the 1998 sheriff’s sale. Therefore, Deanon acquired nothing from Galvan. In contrast, Mag-abo derived her claim from Cabrera, the lawful purchaser at the judicial sale, giving her a prior and superior right. Since an action for unlawful detainer requires the plaintiff to prove a better right of possession, Deanon’s failure to establish this right, based on a derivative claim from a party with no remaining rights, warranted the dismissal of her complaint.
