TALUSAN vs. TAYAG

For purposes of real property taxation under Presidential Decree No. 464, the registered owner of the property is deemed the taxpayer and is therefore the only person entitled to notice of tax delinquency and subsequent auction sale proceedings; unregistered buyers are not entitled to such notice and are bound by the results of the tax sale conducted against the registered owner. Additionally, the expanded jurisdiction of land registration courts under PD 1529 allows them to determine the validity of auction sales in consolidation proceedings, and such determinations are binding on the whole world as in rem judgments, barring subsequent collateral attacks.

The controversy arises from the failure of property buyers to observe the formalities of registration and tax payment. The subject property, a unit in Europa Condominium Villas in Baguio City, was owned by Elias Imperial who emigrated to Australia in 1974. In 1981, petitioners purchased the unit but did not register the deed of sale. For years, real property taxes remained unpaid, leading the City Treasurer to initiate collection proceedings against the registered owner, Imperial, culminating in a public auction sale to Respondent Tayag in 1985. The dispute highlights the conflict between an unregistered buyer in actual possession and a subsequent auction purchaser who secured registration of title, raising fundamental questions regarding the identity of the taxpayer for real property tax purposes and the validity of tax sale notices.

• On December 7, 1981, petitioners Antonio and Celia Talusan purchased the subject condominium unit located in Building IV, Europa Condominium Villas, Baguio City, from the registered owner Elias Imperial for P100,000.00, as evidenced by a Deed of Absolute Sale which was never registered with the Register of Deeds.
• Elias Imperial and his family had emigrated to Australia in 1974, and while the condominium served as a vacation house, Imperial's permanent and known address remained at 145 Ermin Garcia Street, Cubao, Quezon City, as reflected in tax records.
• On October 15, 1985, Respondent Juan Hernandez, as City Treasurer of Baguio City, sent a notice of tax delinquency by registered mail to Elias Imperial at his Quezon City address, demanding payment of P4,039.80 representing unpaid real estate taxes, penalties, and costs, and notifying him that the property would be sold at public auction on December 9, 1985 to satisfy the delinquency.
• On December 9, 1985, the City Treasurer conducted the public auction and sold the property to Respondent Herminigildo Tayag for P4,400.00, the amount of the delinquent taxes, and subsequently issued a Certificate of Sale and Final Bill of Sale in Tayag's favor; the property had an assessed value of P37,310.00 and a fair market value exceeding P300,000.00.
• Prior to the instant action, Respondent Tayag had filed a Petition for Consolidation of Ownership (LRC Adm. Case No. 207-R) before RTC Branch 6 of Baguio City, which rendered a Decision dated September 16, 1987 consolidating ownership in Tayag's favor and declaring the auction sale valid, with a Certificate of Finality issued on October 8, 1987.
• Petitioners claimed they had been in actual, open, public, continuous, and adverse possession of the unit since 1981, and that they offered to pay the tax amount plus interests and expenses to redeem the property, but their offer was rejected, prompting them to file the present action for annulment of the auction sale and damages.

• Petitioners contended that they were deprived of due process because their former counsel received the Court of Appeals decision on December 3, 1997, but only informed them on February 5, 1998, effectively delaying the filing of their Motion for Reconsideration.
• They argued that the auction sale was void for failure to comply with Section 46 of Presidential Decree No. 464, which mandates publication of the notice of tax delinquency in a newspaper of general circulation, claiming no such publication was made.
• They asserted that Section 73 of PD 464 was violated because the notice of public auction was sent to Elias Imperial's residence in Quezon City rather than to the property address as shown in the tax rolls (Unit No. 5, Baden #4105, Europa Condominium Villas, Baguio City), arguing that notice to the residence is only permissible when no address appears in the tax records.
• They maintained that the prior judgment in LRC Adm. Case No. 207-R did not bar the present action because the land registration court lacked jurisdiction to rule on the validity of the auction sale, citing Tiongco v. Philippine Veterans Bank to support the distinction between general jurisdiction and limited land registration jurisdiction.
• They sought annulment on equitable grounds, arguing that the bid price of P4,400.00 was unconscionably low and shocking to the conscience compared to the property's fair market value of over P300,000.00, and that as innocent purchasers in actual possession, equity should favor their claim over the auction buyer.

• Respondents argued that the claim of deprivation of due process was moot because the Court of Appeals accepted, considered, and ruled on the Motion for Reconsideration despite its late filing, thereby affording petitioners full opportunity to be heard.
• They contended that all requirements of notice, publication, and posting under PD 464 were fully complied with by the City Treasurer, rendering the auction sale valid, regular, and binding.
• They asserted that petitioners had no cause of action because they were not the registered owners; under Section 51 of PD 1529, the unregistered deed of sale did not bind third persons, and only the registered owner (Elias Imperial) was entitled to notice of tax delinquency proceedings under the Real Property Tax Code.
• They argued that the prior judgment in LRC Adm. Case No. 207-R, which consolidated ownership in Tayag's favor, had already upheld the validity of the auction sale and was binding on the whole world as an in rem proceeding, thus barring relitigation under the principle of conclusiveness of judgment or res judicata.
• They maintained that Tayag was a buyer in good faith at a regular and lawful public bidding, and that petitioners were guilty of laches for failing to register their purchase or pay real property taxes for years while in possession of the property, effectively sleeping on their rights.

• Procedural Issues: (1) Whether petitioners were deprived of due process by the negligence of their former counsel in failing to immediately notify them of the Court of Appeals decision dated November 20, 1997; (2) Whether the prior final judgment in LRC Adm. Case No. 207-R consolidating ownership in Respondent Tayag's favor bars the present action for annulment of the auction sale under the principle of conclusiveness of judgment.
• Substantive Issues: (1) Whether the auction sale is void for failure to publish the notice of tax delinquency as required by Section 46 of PD 464; (2) Whether the auction sale is void for lack of personal notice to the registered owner at the address specified in the tax rolls pursuant to Section 73 of PD 464; (3) Whether equitable considerations warrant the annulment of the auction sale despite compliance with statutory procedures and the existence of a prior final judgment.

• Procedural: The Court held that the issue regarding counsel's negligence was moot and academic because the Court of Appeals explicitly accepted and considered the Motion for Reconsideration on its merits despite the late filing, thereby affording petitioners due process. Regarding the prior judgment, the Court ruled that under PD 1529 (Property Registration Decree), land registration courts now possess expanded jurisdiction to hear contentious and controversial cases, including petitions for consolidation of ownership that necessitate determination of the validity of underlying auction sales; consequently, the prior judgment in LRC Adm. Case No. 207-R, being a proceeding in rem that had become final and executory, was binding on the whole world and barred relitigation of the auction sale's validity under the principle of conclusiveness of judgment.
• Substantive: The Court held that proceedings for the collection of delinquent real property taxes and subsequent auction sales are in personam, requiring notice to the taxpayer, who is defined as the registered owner of the property; consequently, petitioners, as unregistered buyers, were not entitled to notice and the notice sent to Elias Imperial at his known residence in Quezon City complied with Section 73 of PD 464, which grants the City Treasurer discretion to send notice to the residence if known. The Court ruled that while publication of notice of delinquency is required under Section 46, such publication does not satisfy the in personam requirement of direct notice to the registered owner. The Court affirmed that an unregistered deed of sale does not bind third persons, including the government, and that between two innocent purchasers, the registered buyer (Tayag) has priority over the unregistered possessor (petitioners). Finally, the Court held that equitable considerations cannot override compliance with statutory procedures where the City Treasurer acted in accordance with law, and petitioners' failure to register the sale or pay taxes for years while in possession constituted laches, barring their claim.

• Registered Owner as Taxpayer Doctrine — For purposes of real property taxation, the registered owner of the property is deemed the taxpayer, and therefore is the only person entitled to notice of tax delinquency and subsequent auction sale proceedings. This doctrine was applied to deny petitioners' claim to notice, as they were merely unregistered buyers from the registered owner and had no legal standing to receive tax notices.
• In Personam Nature of Tax Sales — Proceedings for the collection of delinquent real property taxes and the subsequent auction sale are in personam, requiring actual notice to the specific taxpayer (registered owner), unlike land registration proceedings which are in rem. The Court applied this to emphasize that mere publication of notice does not suffice, and direct notice to the registered owner is mandatory to protect the taxpayer's interests.
• Registration as Operative Act — Under Section 51 of PD 1529 (Property Registration Decree), no voluntary instrument purporting to convey registered land shall take effect as a conveyance or bind the land as to third persons until registration; the act of registration is the operative act to convey or affect the land. The Court applied this principle to hold that the unregistered deed of sale in favor of petitioners did not bind the government or the auction sale purchaser, leaving the registered owner as the only party entitled to tax notices.
• Expanded Jurisdiction of Land Registration Courts — Under PD 1529, land registration courts are no longer limited to non-contentious applications but may now hear and decide controversial and contentious cases, including petitions for consolidation of ownership that require determination of the validity of underlying auction sales. This doctrine was invoked to uphold the binding effect of the prior judgment in LRC Adm. Case No. 207-R on the validity of the tax sale.
• Conclusiveness of Judgment — A final judgment in a land registration proceeding (in rem) that has ordered the confirmation and registration of title binds the whole world and bars subsequent relitigation of issues necessarily determined therein, such as the validity of the tax auction sale. The Court applied this to dismiss petitioners' attempt to retry the validity of the sale already upheld in the consolidation case.
• Laches — The failure to assert a right for an unreasonable length of time, coupled with negligence or omission to assert it while holding possession that puts others in ignorance or false security, bars relief. The Court applied this to petitioners who failed to register their purchase or pay taxes for years while in possession of the property, rendering their claim unenforceable against the registered title of Respondent Tayag.

• "For purposes of real property taxation, the registered owner of a property is deemed the taxpayer and, hence, the only one entitled to a notice of tax delinquency and the resultant proceedings relative to an auction sale."
• "Laws exist to be followed, failing in which the price must be paid."
• "The law helps the vigilant, but not those who sleep on their rights, for time is a means of obliterating actions."
• "Verily, time runs against the slothful and the contemners of their own rights."
• "Matters of notice and publication in tax sales are factual questions that cannot be determined by this Court."
• "Thus, insofar as third persons are concerned, it is the registration of the deed of sale that can validly transfer or convey a person's interest in a property."

• Tiongco v. Philippine Veterans Bank, 212 SCRA 176 (1992) — Cited by petitioners to argue that land registration courts lack jurisdiction to rule on the validity of auction sales, but distinguished by the Court because the cited case involved a Petition for Surrender of Certificates of Title rather than a Petition for Consolidation of Ownership, and because PD 1529 has since expanded land registration court jurisdiction.
• Pecson v. Court of Appeals, 222 SCRA 580 (1993) — Followed by the Court in interpreting Section 73 of PD 464, holding that the City Treasurer has discretionary authority to send notice of auction sale either to the address shown in tax rolls or to the taxpayer's residence if known, thereby validating the notice sent to Imperial's Quezon City address.
• Tañedo v. Court of Appeals, 252 SCRA 80 (1996) — Cited for the principle that between two innocent purchasers, the one who registers the sale has a preferred right over the unregistered buyer, even if the latter is in actual possession, supporting the priority of Respondent Tayag's registered title.
• Estate of the Late Mercedes Jacob v. Court of Appeals, 283 SCRA 474 (1997) and Ignacio v. Court of Appeals, 246 SCRA 242 (1995) — Cited to support the expanded jurisdiction of land registration courts under PD 1529 to hear contentious cases and determine questions of ownership necessarily tied to registration proceedings.
• De Knecht v. Court of Appeals, 290 SCRA 223 (1998) — Cited to establish that matters of notice and publication in tax sales are factual questions generally not reviewable in a Petition for Review on Certiorari under Rule 45.
• Garbin v. Court of Appeals, 253 SCRA 187 (1996) and Salandanan v. Court of Appeals, 290 SCRA 671 (1998) — Cited in support of the doctrine of laches applied against petitioners who slept on their rights by failing to register their purchase or pay taxes for an extended period.

• Section 46 of Presidential Decree No. 464 (Real Property Tax Code) — Cited regarding the publication requirements for notice of tax delinquency; the Court noted that while this section requires publication, tax sale proceedings remain in personam requiring personal notice to the taxpayer, and mere publication does not cure the lack of such personal notice.
• Section 73 of Presidential Decree No. 464 (Real Property Tax Code) — Cited regarding the requirement that notice of public auction be sent to the delinquent taxpayer either at the address shown in tax rolls or at his residence if known to the treasurer; the Court upheld the City Treasurer's discretion in choosing to send notice to the owner's known residence in Quezon City rather than the property address in Baguio City.
• Section 51 of Presidential Decree No. 1529 (Property Registration Decree) — Cited to establish that unregistered deeds of sale do not bind the land or third persons, and that registration is the operative act to convey title, which was applied to hold that petitioners' unregistered purchase did not bind the government or the auction buyer.
• Rule 45 of the Rules of Court — Referenced as the procedural basis for the Petition for Review on Certiorari, with the Court noting its limited scope generally precludes review of factual questions such as compliance with notice requirements, and that the Court deviated from this rule only to provide complete adjudication of the case.
