Hu v. Unico
REITERATIONFacts
The Antecedents: On December 13, 1978, respondents Spouses Renato and Maria Aurora J. Unico purchased a 800-square meter residential property in Fairview Park Village, Quezon City. They fully paid the purchase price and constructed a house on the land, where they resided. However, they failed to register the sale, declare the property in their names for taxation purposes, or pay the associated realty taxes. Procedural History: Due to the respondents' tax delinquency, the property was sold at public auction on March 5, 1984, and purchased by petitioners Spouses Hu Chuan Hai and Leoncia Lim Hu. Petitioners subsequently obtained a court order for consolidation of ownership and a new title was issued in their names. When respondents attempted to pay realty taxes on December 19, 1986, they discovered the property was already registered under the petitioners' names. Respondents then filed a complaint for annulment of the tax sale and damages, arguing they were deprived of due process as they were not notified of the tax sale. The Regional Trial Court (RTC) nullified the tax sale, finding that the notice was sent to the previous owners instead of the actual occupants. The Court of Appeals affirmed the RTC's decision. The Petition: Petitioners seek review of the Court of Appeals' decision, arguing that the lower courts erred in nullifying the tax sale. They contend that they should not be prejudiced by the respondents' failure to register the sale and declare the property for tax purposes as mandated by law. Petitioners assert that the tax sale was valid because the notice was correctly sent to the registered owners at the time, the spouses de los Santos, as the transfer to the respondents had not been registered. The Supreme Court granted the petition, reversing the decisions of the lower courts and dismissing the respondents' complaint on the ground of res judicata, declaring the tax sale valid.
Issue(s)
Whether the tax sale conducted on March 5, 1984, is valid despite the notice of sale and advertisement being sent to the original registered owners (spouses de los Santos) instead of the unregistered transferees (spouses Unico). Whether the decision in the petition for consolidation of ownership (LRC Case No. Q-3458) bars the subsequent action for annulment of the tax sale (Civil Case No. Q-50553) on the ground of res judicata.
Ruling
The petition is GRANTED. The decision of the Court of Appeals affirming the Regional Trial Court's decision is REVERSED and SET ASIDE. A new judgment is entered dismissing Civil Case No. Q-50553 on the ground of res judicata. The March 5, 1984 tax sale is declared VALID.
Ratio Decidendi
On Issue 1 (Validity of Tax Sale and Notice): The Court held that the tax sale was valid. It reiterated the settled rule that for purposes of real property taxation, the registered owner of the property is deemed the taxpayer. A local treasurer cannot rely solely on the tax declaration but must verify with the Register of Deeds who the registered owner is. In this case, the respondents (spouses Unico) failed to register the transfer of the property and did not declare it in their names for taxation purposes as required by Section 6 of PD 464. Consequently, the spouses de los Santos remained the registered owners in both the Torrens title and the tax declaration. Therefore, the City Treasurer correctly sent the notice of the tax sale and advertisement to the spouses de los Santos, and the subsequent tax sale was valid. The respondents' failure to register the sale and pay taxes, which led to the tax sale, could not prejudice the petitioners, who were purchasers in the auction. On Issue 2 (Res Judicata): The Court found that the action for annulment of the tax sale was barred by res judicata. It cited the ruling in Talusan v. Tayag, which held that a decision in a land registration court case for consolidation of ownership precludes another action for annulment of the auction sale. The September 8, 1986 decision of the RTC Branch 93 in LRC Case No. Q-3458(86), which granted the consolidation of ownership, had already passed upon the validity of the title that stemmed from the tax sale. Therefore, the RTC Branch 104 should have dismissed Civil Case No. Q-50553 on the ground of res judicata, as the matter had already been definitively passed upon and decided in a prior case involving the same parties and subject matter.
Main Doctrine
A prior judgment in a land registration proceeding, such as a petition for consolidation of ownership, bars a subsequent suit for annulment of a tax sale involving the same property on the ground of res judicata. Furthermore, for real property tax purposes, the registered owner appearing in the Torrens title and tax declaration is considered the taxpayer, and notices of tax sale must be sent to this registered owner, not the unregistered transferee or occupant, to ensure the validity of the sale.
