Eastern Heights Investments and Development Corp. v. Tagumpay Realty Corp.

Case Decision Date

G.R. No. 240671 (Resolution) December 6, 2021

This case is DIRECT to the Topic/Subtopic of Jurisdiction. Petitioner Eastern Heights, registered owner of a Taytay, Rizal property sold at a tax delinquency public auction to respondent Tagumpay Realty, resisted Tagumpay Realty's petition to surrender its withheld duplicate title, arguing the trial court lacked jurisdiction over its person for want of valid summons and over the subject matter because, as a land registration court, it could resolve title-surrender petitions only where the tax sale's validity was uncontested. The Supreme Court denied Eastern Heights' petition and affirmed the surrender order. On jurisdiction over the person, the Court held that although merely including other grounds in a motion to dismiss did not, under the rule then in force, amount to voluntary appearance, Eastern Heights' subsequent active participation in the proceedings cured any defect in service of summons. On jurisdiction over the subject matter, the Court reaffirmed that Section 2, P.D. 1529 empowers Regional Trial Courts, whether sitting as land registration courts or as courts of general jurisdiction, to hear and determine all questions — even contentious ones like a tax sale's validity — arising from petitions filed after registration, expressly abandoning the contrary view in Tagaytay-Taal Tourist Dev't Corp. v. CA.

Core Doctrine

A defect in service of summons is cured by the defendant's subsequent voluntary, active participation in the proceedings. Under Section 2, P.D. 1529, a Regional Trial Court sitting as a land registration court has the same jurisdiction as one exercising general jurisdiction to resolve even contentious and substantial questions — including a tax sale's validity — arising from petitions filed after original registration; any prior doctrine confining such courts to uncontroverted matters is abandoned.

Core Doctrine

Facts

Eastern Heights' 330-square-meter Taytay property, covered by TCT No. 285425, was sold at a public auction for tax delinquency in the Provincial Capitol of Antipolo City. (The auction was held on 9 February 2012 by the local government of Taytay, Rizal; the one-year redemption period ran out unused, and the Deed of Conveyance issued on 8 May 2013. Everything the company later argued about want of notice was raised only after that clock had already run.)
Tagumpay Realty won as highest bidder, received a certificate of sale, and, after the redemption period lapsed unexercised, a deed of conveyance.
Eastern Heights did not surrender its owner's duplicate TCT, prompting Tagumpay Realty to petition the RTC-Antipolo (Branch 98) for surrender or cancellation. (Filed 6 November 2013 as LRC Case No. 12-5570, under Sections 75 and 107 of P.D. 1529. It is a petition filed after original registration, and that is precisely the class Section 2 commits to the Regional Trial Court's ordinary jurisdiction.)
Eastern Heights filed a "Voluntary Special Appearance and Urgent Motion to Dismiss," contending the petition misnamed it as "Eastern Heights Investments," that it was never served summons, and that the auction should be nullified for want of demand and notice under Sections 254 and 258, R.A. 7160. Labelled a special appearance, but in the same paper it attacked the tax sale on the merits under Sections 254 and 258 of R.A. 7160 — and asking the court to rule on the merits is what cured the missing summons.
Tagumpay Realty moved to amend the petition to correct the name.
Eastern Heights opposed, arguing the amendment would confer jurisdiction the RTC otherwise lacked, citing Alto Surety & Insurance Co. v. Limcaco and Tagaytay-Taal Tourist Dev't Corp. v. CA.
On September 26, 2013, the RTC allowed the amendment as a mere typographical correction and later denied reconsideration.
Eastern Heights' counsel attended, then later missed, a scheduled hearing despite notice.
The RTC allowed Tagumpay Realty to present evidence ex parte.
On August 7, 2015, the RTC granted the petition, ordering surrender or cancellation of the TCT and issuance of a new one to Tagumpay Realty; reconsideration was denied.
The Court of Appeals affirmed on November 7, 2017, and denied reconsideration on July 11, 2018.
Eastern Heights then petitioned the Supreme Court, decided December 6, 2021.

Arguments of the Parties

Petitioner. Eastern Heights argued the amendment correcting its name was improper, that the RTC never validly acquired jurisdiction over its person absent valid summons, that as a land registration court the RTC could resolve the surrender petition only if the tax sale's validity was unchallenged, and that it could challenge that validity without the deposit Section 267, R.A. 7160 requires.

Respondent. Tagumpay Realty maintained the name correction was clerical, that Eastern Heights' conduct amounted to voluntary submission to the court's jurisdiction, that Section 2, P.D. 1529 empowered the RTC to resolve even the contested tax-sale question, and that Eastern Heights' failure to deposit under Section 267 barred its challenge.

Common Ground / Stipulations (if any). Both parties treated the underlying attachments to the petition — the TCT, tax declaration, certificate of sale, and deed of conveyance — as consistently naming the same corporate entity, disputing only the legal effect of the initial misnomer.

Issue

MAIN ISSUE (Jurisdiction-centered). Whether the RTC acquired jurisdiction over the person of Eastern Heights despite the defective service of summons, and whether, as a land registration court, it had jurisdiction over the subject matter to resolve a petition for surrender of title where the underlying tax sale's validity was placed in issue.

SECONDARY ISSUES. Whether the amendment correcting Eastern Heights' corporate name was proper; whether Eastern Heights' failure to deposit under Section 267, R.A. 7160 barred its challenge to the tax sale's validity.

ANCILLARY / INCIDENTAL ISSUES (if any). None separately resolved.

Ruling

On the MAIN ISSUE: YES to both — jurisdiction over the person was acquired through Eastern Heights' voluntary, active participation, curing any defect in summons; and jurisdiction over the subject matter existed because Section 2, P.D. 1529 empowers the RTC to resolve even contentious questions, including a tax sale's validity, arising from post-registration petitions. Secondary issues: the amendment was a proper clerical correction; and Eastern Heights' non-compliance with Section 267's deposit requirement barred its challenge to the tax sale. The dispositive portion reads verbatim: "WHEREFORE, the petition is DENIED. The Decision dated November 7, 2017 and the Resolution dated July 11, 2018 of the Court of Appeals in CA-G.R. CV No. 107794 are hereby AFFIRMED. SO ORDERED."

Ratio

On jurisdiction over the person, the Court agreed that, under the then-governing Section 20, Rule 14, "[t]he inclusion in a motion to dismiss of other grounds aside from lack of jurisdiction over the person shall not be deemed a voluntary appearance," so the Court of Appeals erred in treating Eastern Heights' motion itself as voluntary appearance.
Nonetheless, "petitioner's subsequent conduct demonstrated its voluntary submission to the court's jurisdiction": its counsel appeared at hearings, and it filed a motion for reconsideration, a notice of appeal, and an appellant's brief — "active participation tantamount to a voluntary appearance," curing the defective summons.
On subject-matter jurisdiction, the Court distinguished Alto Surety, where the offending petition was filed within an unrelated collection case rather than as an original action.
Here, Tagumpay Realty's petition was filed as "an original action before the RTC sitting not only as a land registration court but also as a court of general jurisdiction."
Invoking Section 2, P.D. 1529 and its own line of authority, the Court held that because the statute "eliminated" the distinction between a court's general and its limited cadastral jurisdiction, the RTC now has "the power to hear and determine all questions, even contentious and substantial ones," including the tax sale's validity, so that "[w]hether the RTC resolves an issue in the exercise of its general jurisdiction or of its limited jurisdiction as a special court is only a matter of procedure and has nothing to do with the question of jurisdiction."
On this basis, the Court declared the contrary 1995 ruling in Tagaytay-Taal Tourist Dev't Corp. v. CA "already abandoned."

Doctrine

Doctrines / Rules / Principles Laid Down.

A defect in service of summons is cured by the defendant's subsequent voluntary, active participation in the proceedings.
Under Section 2, P.D. 1529, a Regional Trial Court sitting as a land registration court has the same jurisdiction as one exercising general jurisdiction to resolve even contentious and substantial questions — including a tax sale's validity — arising from petitions filed after original registration; any prior doctrine confining such courts to uncontroverted matters is abandoned.

Distinctions / Limitations / Qualifications.

The Court did not dispense with Section 267's deposit requirement for challenging a tax sale's validity; it treated that as an independent, still-binding precondition distinct from the court's jurisdiction to hear the surrender petition itself.

Topic/Subtopic Integration (Mandatory).

DIRECT: this Resolution both reinforces Section 2, P.D. 1529's broad jurisdictional grant — expressly abandoning Tagaytay-Taal's narrower view — and clarifies the related but distinct doctrine of curing defective summons through voluntary appearance, both squarely within the Jurisdiction subtopic.

Separate Opinions

None. Perlas-Bernabe, S.A.J. (Chairperson), Hernando, and J. Lopez, JJ., concurred; Gaerlan, J., on official leave.

TOPIC/SUBTOPIC FOCUS: Chapter I – General Provisions (Sections 1–3) > Jurisdiction

I. Gist and Central Doctrine

The relationship of the case of Eastern Heights Investments and Development Corp. v. Tagumpay Realty Corp. to the requested topic of Jurisdiction is DIRECT. The controversy arose when Respondent Tagumpay Realty Corporation filed a petition before the Regional Trial Court to compel the surrender or cancellation of the owner's duplicate certificate of title following a purchase at a municipal tax delinquency sale. Petitioner Eastern Heights Investments and Development Corporation opposed the petition on the ground that the Regional Trial Court, sitting as a land registration court, had no jurisdiction over contentious and substantial issues such as the validity of a tax delinquency sale. The Supreme Court denied the petition, thereby affirming the decision of the Court of Appeals and the Regional Trial Court. The central doctrine established by the Supreme Court is that Section 2 of Presidential Decree No. 1529 has completely eliminated the distinction between the general jurisdiction of the Regional Trial Court and the limited jurisdiction of the Regional Trial Court sitting as a land registration or cadastral court. Consequently, the Regional Trial Court has full jurisdiction to hear and decide both non-controversial and highly contentious post-registration petitions, including those involving the validity of a tax delinquency sale, provided that any party challenging the tax sale complies with the mandatory jurisdictional deposit requirement under Section 267 of Republic Act No. 7160.

III. Arguments of the Parties

A. Petitioner / Prosecution (Petitioner Eastern Heights Investments and Development Corporation)

Petitioner Eastern Heights argued that the Regional Trial Court sitting as a land registration court did not acquire jurisdiction over the person of Petitioner Eastern Heights because the original petition impleaded a different entity ("Eastern Heights Investments") and no valid service of summons was made on Petitioner Eastern Heights.
Petitioner Eastern Heights contended that the Regional Trial Court sitting as a land registration court lacked jurisdiction over the subject matter of the petition because land registration proceedings are summary in nature, and the Regional Trial Court has no authority to order the surrender or cancellation of an owner's duplicate certificate of title when the validity of the underlying tax delinquency sale is actively contested and controversial, citing Alto Surety & Insurance Co., Inc. v. Limcaco and Tagaytay-Taal Tourist Dev't Corporation v. Court of Appeals.
Petitioner Eastern Heights asserted that the municipal tax delinquency sale was null and void because the local government of Taytay, Rizal, failed to comply with the mandatory requirements under Section 254 and Section 258 of Republic Act No. 7160, specifically by failing to serve a notice of levy, demand for payment, or deed of conveyance on Petitioner Eastern Heights.
Petitioner Eastern Heights maintained that the jurisdictional deposit requirement under Section 267 of Republic Act No. 7160 is inapplicable because the deposit is only required in actions initiated by a taxpayer to annul a tax sale, and not when the taxpayer merely sets up the invalidity of the tax sale as an affirmative defense in a post-registration proceeding initiated by a purchaser.

B. Respondent / Defense (Respondent Tagumpay Realty Corporation)

Respondent Tagumpay argued that the amendment of the petition from "Eastern Heights Investments" to "Eastern Heights Investments and Development Corporation" was a mere formal correction of a clerical or typographical error, which was permissible as a matter of right because Petitioner Eastern Heights had not filed any responsive pleading.
Respondent Tagumpay contended that the Regional Trial Court sitting as a land registration court acquired jurisdiction over the person of Petitioner Eastern Heights because Petitioner Eastern Heights voluntarily appeared by filing a motion to dismiss that sought affirmative reliefs other than the mere dismissal of the petition for lack of personal jurisdiction.
Respondent Tagumpay asserted that the Regional Trial Court is vested with full and general jurisdiction under Section 2, Section 75, and Section 107 of Presidential Decree No. 1529 to resolve both non-controversial and highly contentious issues in land registration and post-registration proceedings, thereby avoiding multiplicity of suits and simplifying registration proceedings.
Respondent Tagumpay maintained that the Regional Trial Court and the Court of Appeals correctly refused to entertain the challenge of Petitioner Eastern Heights to the validity of the tax sale because Petitioner Eastern Heights failed to deposit with the court the purchase price plus interest as mandatorily required under Section 267 of Republic Act No. 7160.

C. Common Ground

The adversarial parties did not stipulate to any common ground regarding the validity of the tax sale or the ownership of the subject property. However, both Petitioner Eastern Heights and Respondent Tagumpay recognized that the subject property was originally registered under Transfer Certificate of Title No. 285425 in the name of Petitioner Eastern Heights, and that Respondent Tagumpay purchased the subject property at a tax delinquency sale on February 9, 2012.

IV. Issues

A. Main Issue

Whether the Regional Trial Court, sitting as a land registration court, is vested with jurisdiction under Section 2, Section 75, and Section 107 of Presidential Decree No. 1529 to hear, determine, and resolve contentious and substantial issues, such as the validity of a municipal tax delinquency sale, in a post-registration proceeding to compel the surrender or cancellation of an owner's duplicate certificate of title.

B. Secondary Issues

Whether the Regional Trial Court acquired jurisdiction over the person of Petitioner Eastern Heights Investments and Development Corporation despite the failure of Respondent Tagumpay Realty Corporation to serve summons on Petitioner Eastern Heights under the correct corporate name in the original petition.
Whether Petitioner Eastern Heights Investments and Development Corporation can validly challenge the validity of the tax delinquency sale in a post-registration proceeding without complying with the jurisdictional deposit requirement set forth in Section 267 of Republic Act No. 7160.

V. Ruling / Disposition

A. MAIN ISSUE: YES. The Supreme Court dismissed the petition and affirmed the Court of Appeals Decision because the Regional Trial Court is fully vested with jurisdiction. Under Section 2 of Presidential Decree No. 1529, the historical distinction between the general jurisdiction of the Regional Trial Court and the limited, summary jurisdiction of the Regional Trial Court when acting merely as a land registration or cadastral court was completely eliminated. Consequently, the Regional Trial Court has full authority to hear, determine, and resolve all questions, including contentious and substantial issues like the validity of a tax delinquency sale, in post-registration proceedings filed under Section 75 and Section 107 of Presidential Decree No. 1529.
B. SECONDARY ISSUES:
1. YES. The Supreme Court affirmed that the Regional Trial Court acquired jurisdiction over the person of Petitioner Eastern Heights because Petitioner Eastern Heights voluntarily submitted to the jurisdiction of the Regional Trial Court. By filing a Voluntary Special Appearance and Urgent Motion to Dismiss that raised substantive defenses and sought the nullification of the tax delinquency sale, and by actively participating in the subsequent proceedings, filing briefs, and seeking affirmative reliefs, Petitioner Eastern Heights waived any defect in the service of summons under Section 20, Rule 14 of the then Rules of Court.
2. NO. The Supreme Court affirmed that the Regional Trial Court cannot entertain any challenge to the validity of the tax delinquency sale because compliance with Section 267 of Republic Act No. 7160 is a mandatory jurisdictional prerequisite. Since Petitioner Eastern Heights failed to deposit with the court the amount for which the subject property was sold plus interest, the challenge of Petitioner Eastern Heights to the tax sale was legally ineffective, and the tax sale remained valid and binding.

Verbatim Dispositive Portion

"WHEREFORE, the petition is DENIED. The Decision dated November 7, 2017 and the Resolution dated July 11, 2018 of the Court of Appeals in CA-G.R. CV No. 107794 are hereby AFFIRMED."

VI. Ratio Decidendi and Doctrines

A. Ratio Decidendi

The Plenary Jurisdiction of the Regional Trial Court under Section 2 of Presidential Decree No. 1529: Under Section 2 of Presidential Decree No. 1529, the Regional Trial Court is vested with exclusive original jurisdiction over all applications for original registration of title to lands and over all petitions filed after original registration of title, with power to hear and determine all questions arising upon such applications or petitions.
Elimination of the General vs. Limited Jurisdiction Distinction: The enactment of Presidential Decree No. 1529 completely eliminated the distinction between the general jurisdiction of the Regional Trial Court and the limited jurisdiction formerly conferred upon the Regional Trial Court when acting merely as a cadastral or land registration court. The legislative intent behind this change was to avoid multiplicity of suits and simplify registration proceedings by conferring upon the Regional Trial Court the authority to resolve both non-controversial and highly contentious or substantial issues in a single proceeding.
Abandonment of the Summary Doctrine in Post-Registration Incidents: Prior to the effectivity of Presidential Decree No. 1529, summary reliefs under Section 112 of Act No. 496, such as an action to compel the surrender of an owner's duplicate certificate of title, could only be granted if there was complete unanimity among the parties or no adverse claim. However, under Section 2 of Presidential Decree No. 1529, the land registration court is no longer fettered by this summary limitation. The court is fully authorized to decide contentious issues, and the old doctrines in Alto Surety & Insurance Co., Inc. v. Limcaco and Tagaytay-Taal Tourist Dev't Corporation v. Court of Appeals, which barred land registration courts from resolving controversial matters, are completely abandoned.
Jurisdiction over Post-Registration Petitions under Sections 75 and 107: Under Section 75 and Section 107 of Presidential Decree No. 1529, a purchaser of registered land at a public auction, such as a tax delinquency sale, may petition the Regional Trial Court to compel the surrender of the owner's duplicate certificate of title for the purpose of registering the transfer. If the registered owner refuses or fails to surrender the duplicate title, the Regional Trial Court, in the exercise of the Regional Trial Court's broad jurisdiction under Section 2, is fully authorized to order the cancellation of the outstanding owner's duplicate title and direct the issuance of a new transfer certificate of title in the name of the purchaser.
Jurisdictional Deposit Requirement under Section 267 of Republic Act No. 7160: Section 267 of Republic Act No. 7160, otherwise known as the Local Government Code of 1991, provides a mandatory jurisdictional requirement that no court shall entertain any action assailing the validity of a tax sale at public auction unless the taxpayer deposits with the court the amount for which the real property was sold plus interest. This deposit requirement is a condition precedent that applies whenever the validity of a tax sale is challenged, whether through a direct complaint or as an defense or opposition to a petition for surrender of title under Presidential Decree No. 1529. The failure of the taxpayer to make this deposit deprives the court of the authority to hear or resolve any challenge to the validity of the tax sale.
Acquisition of Jurisdiction over the Person via Voluntary Appearance: Under Section 20, Rule 14 of the then applicable Rules of Court, a defendant's voluntary appearance in an action is equivalent to the service of summons. Although a special appearance to challenge the court's jurisdiction over the person does not constitute voluntary submission, the inclusion of other grounds or substantive defenses, such as a prayer to nullify a tax sale, and the subsequent active participation of the party in the trial, appeal, and filing of briefs, constitutes a waiver of any defect in the service of summons and vests the Regional Trial Court with full personal jurisdiction.

B. Doctrines/Rules

1. Jurisdiction Over Post-Registration Petitions

Section 2 of Presidential Decree No. 1529 provides:

"Courts of First Instance [now Regional Trial Courts] shall have exclusive jurisdiction over all applications for original registration of title to lands, including improvements and interests therein, and over all petitions filed after original registration of title, with power to hear and determine all questions arising upon such applications or petitions."

2. Surrender of Withheld Duplicate Title

Section 107 of Presidential Decree No. 1529 provides:

"SECTION 107. Surrender of Withheld Duplicate Certificates. — Where it is necessary to issue a new certificate of title pursuant to any involuntary instrument which divests the title of the registered owner against his consent or where a voluntary instrument cannot be registered by reason of the refusal or failure of the holder to surrender the owner's duplicate certificate of title, the party in interest may file a petition in court to compel surrender of the same to the Register of Deeds. The court, after hearing, may order the registered owner or any person withholding the duplicate certificate to surrender the same, and direct the entry of a new certificate or memorandum upon such surrender. If the person withholding the duplicate certificate is not amenable to the process of the court, or if not any reason the outstanding owner's duplicate certificate cannot be delivered, the court may order the annulment of the same as well as the issuance of a new certificate of title in lieu thereof. Such new certificate and all duplicates thereof shall contain a memorandum of the annulment of the outstanding duplicate."

3. Mandatory Deposit in Tax Sale Challenges

Section 267 of Republic Act No. 7160 provides:

"No court shall entertain any action assailing the validity of any sale at public auction of real property or rights therein under this Title until the taxpayer shall have deposited with the court the amount for which the real property was sold, together with interest of two percent (2%) per month from the date of sale to the time of the institution of the action."

C. Limitations/Exceptions

No Reopening of Original Decrees: While Section 2 and Section 108 of Presidential Decree No. 1529 grant the Regional Trial Court broad jurisdiction to hear contentious cases, this authority is strictly limited and does not extend to the reopening of the original decree of registration. The land registration court cannot review or set aside the original judgment that brought the land under the Torrens system.
Protection of Innocent Purchasers for Value: The power of the court to alter, amend, or cancel a certificate of title under Section 108 of Presidential Decree No. 1529 is subject to the strict limitation that nothing shall be ordered or done by the court which will impair the title or other interest of a purchaser holding a certificate for value and in good faith, or the heirs and assigns of the purchaser, without the written consent of the purchaser or the heirs and assigns of the purchaser.

D. Topic Integration

The relationship of the case of Eastern Heights Investments and Development Corp. v. Tagumpay Realty Corp. to the requested topic of Jurisdiction is DIRECT. This case is a premier contemporary authority clarifying the expansive scope of the jurisdiction of Regional Trial Courts sitting as land registration courts under Chapter I of Presidential Decree No. 1529. By affirming that the historical division between general civil jurisdiction and limited cadastral jurisdiction has been completely abolished by Section 2 of Presidential Decree No. 1529, the Supreme Court settled that the land registration court is a court of general jurisdiction fully competent to resolve highly contentious and substantial property disputes, such as the validity of tax delinquency sales, in post-registration incidents. This case is highly illustrative of the modern legislative policy of avoiding multiplicity of suits and streamlining land registration procedures by vesting the Regional Trial Court with plenary powers over all land-related applications and petitions.

VII. Separate Opinions

No. 240671, December 6, 2021) do not contain the text, summaries, or citations of any separate concurring or dissenting opinions. Consequently, the details of any separate opinions are NOT IN RECORD.

Cited Laws & Provisions

Every statute, rule, and issuance the decision turns on — the text as written, and the work it does in this case.

Special Law

Section 2, P.D. No. 1529

Nature of registration proceedings; jurisdiction of courts

Presidential Decree No. 1529 (Property Registration Decree, 1978)

Judicial proceedings for the registration of lands throughout the Philippines shall be in rem and shall be based on the generally accepted principles underlying the Torrens system.

Courts of First Instance shall have exclusive jurisdiction over all applications for original registration of title to lands, including improvements and interests therein, and over all petitions filed after original registration of title, with power to hear and determine all questions arising upon such applications or petitions. The court through its clerk of court shall furnish the Land Registration Commission with two certified copies of all pleadings, exhibits, orders, and decisions filed or issued in applications or petitions for land registration, with the exception of stenographic notes, within five days from the filing or issuance thereof.

Why it is cited here

The grant of jurisdiction the case relies on, and it is worth separating the two kinds of jurisdiction in play.

Section 2 gives the court "exclusive jurisdiction over all applications for original registration … and over all petitions filed after original registration, with power to hear and determine all questions arising upon such applications or petitions." That is jurisdiction over the subject matter, and it comes from the statute.

Jurisdiction over the person is a different thing, acquired by valid service of summons or by the defendant's voluntary appearance. A defect in service goes to the second, never the first.

Hence the holding: a defect in service of summons is cured by the defendant's subsequent voluntary, active participation in the proceedings. Someone who files pleadings, argues the merits, and seeks affirmative relief has submitted to the court, and cannot afterwards complain that he was not properly summoned.

The distinction is worth holding firmly because the consequences differ sharply. Lack of subject-matter jurisdiction cannot be waived or cured and makes the judgment void. Lack of personal jurisdiction is a defense personal to the defendant, and he may give it up — including by conduct.

Facts

Eastern Heights' 330-square-meter Taytay property, covered by TCT No. 285425, was sold at a public auction for tax delinquency in the Provincial Capitol of Antipolo City. (The auction was held on 9 February 2012 by the local government of Taytay, Rizal; the one-year redemption period ran out unused, and the Deed of Conveyance issued on 8 May 2013. Everything the company later argued about want of notice was raised only after that clock had already run.)
Tagumpay Realty won as highest bidder, received a certificate of sale, and, after the redemption period lapsed unexercised, a deed of conveyance.
Eastern Heights did not surrender its owner's duplicate TCT, prompting Tagumpay Realty to petition the RTC-Antipolo (Branch 98) for surrender or cancellation. (Filed 6 November 2013 as LRC Case No. 12-5570, under Sections 75 and 107 of P.D. 1529. It is a petition filed after original registration, and that is precisely the class Section 2 commits to the Regional Trial Court's ordinary jurisdiction.)
Eastern Heights filed a "Voluntary Special Appearance and Urgent Motion to Dismiss," contending the petition misnamed it as "Eastern Heights Investments," that it was never served summons, and that the auction should be nullified for want of demand and notice under Sections 254 and 258, R.A. 7160. Labelled a special appearance, but in the same paper it attacked the tax sale on the merits under Sections 254 and 258 of R.A. 7160 — and asking the court to rule on the merits is what cured the missing summons.
Tagumpay Realty moved to amend the petition to correct the name.
Eastern Heights opposed, arguing the amendment would confer jurisdiction the RTC otherwise lacked, citing Alto Surety & Insurance Co. v. Limcaco and Tagaytay-Taal Tourist Dev't Corp. v. CA.
On September 26, 2013, the RTC allowed the amendment as a mere typographical correction and later denied reconsideration.
Eastern Heights' counsel attended, then later missed, a scheduled hearing despite notice.
The RTC allowed Tagumpay Realty to present evidence ex parte.
On August 7, 2015, the RTC granted the petition, ordering surrender or cancellation of the TCT and issuance of a new one to Tagumpay Realty; reconsideration was denied.
The Court of Appeals affirmed on November 7, 2017, and denied reconsideration on July 11, 2018.
Eastern Heights then petitioned the Supreme Court, decided December 6, 2021.

Arguments of the Parties

ANCILLARY / INCIDENTAL ISSUES (if any). None separately resolved.

Ruling

Ratio

On jurisdiction over the person, the Court agreed that, under the then-governing Section 20, Rule 14, "[t]he inclusion in a motion to dismiss of other grounds aside from lack of jurisdiction over the person shall not be deemed a voluntary appearance," so the Court of Appeals erred in treating Eastern Heights' motion itself as voluntary appearance.
Nonetheless, "petitioner's subsequent conduct demonstrated its voluntary submission to the court's jurisdiction": its counsel appeared at hearings, and it filed a motion for reconsideration, a notice of appeal, and an appellant's brief — "active participation tantamount to a voluntary appearance," curing the defective summons.
On subject-matter jurisdiction, the Court distinguished Alto Surety, where the offending petition was filed within an unrelated collection case rather than as an original action.
Here, Tagumpay Realty's petition was filed as "an original action before the RTC sitting not only as a land registration court but also as a court of general jurisdiction."
Invoking Section 2, P.D. 1529 and its own line of authority, the Court held that because the statute "eliminated" the distinction between a court's general and its limited cadastral jurisdiction, the RTC now has "the power to hear and determine all questions, even contentious and substantial ones," including the tax sale's validity, so that "[w]hether the RTC resolves an issue in the exercise of its general jurisdiction or of its limited jurisdiction as a special court is only a matter of procedure and has nothing to do with the question of jurisdiction."
On this basis, the Court declared the contrary 1995 ruling in Tagaytay-Taal Tourist Dev't Corp. v. CA "already abandoned."

Doctrine

Doctrines / Rules / Principles Laid Down.

A defect in service of summons is cured by the defendant's subsequent voluntary, active participation in the proceedings.
Under Section 2, P.D. 1529, a Regional Trial Court sitting as a land registration court has the same jurisdiction as one exercising general jurisdiction to resolve even contentious and substantial questions — including a tax sale's validity — arising from petitions filed after original registration; any prior doctrine confining such courts to uncontroverted matters is abandoned.

Distinctions / Limitations / Qualifications.

The Court did not dispense with Section 267's deposit requirement for challenging a tax sale's validity; it treated that as an independent, still-binding precondition distinct from the court's jurisdiction to hear the surrender petition itself.

Topic/Subtopic Integration (Mandatory).

DIRECT: this Resolution both reinforces Section 2, P.D. 1529's broad jurisdictional grant — expressly abandoning Tagaytay-Taal's narrower view — and clarifies the related but distinct doctrine of curing defective summons through voluntary appearance, both squarely within the Jurisdiction subtopic.

III. Arguments of the Parties

A. Petitioner / Prosecution (Petitioner Eastern Heights Investments and Development Corporation)

Petitioner Eastern Heights argued that the Regional Trial Court sitting as a land registration court did not acquire jurisdiction over the person of Petitioner Eastern Heights because the original petition impleaded a different entity ("Eastern Heights Investments") and no valid service of summons was made on Petitioner Eastern Heights.
Petitioner Eastern Heights contended that the Regional Trial Court sitting as a land registration court lacked jurisdiction over the subject matter of the petition because land registration proceedings are summary in nature, and the Regional Trial Court has no authority to order the surrender or cancellation of an owner's duplicate certificate of title when the validity of the underlying tax delinquency sale is actively contested and controversial, citing Alto Surety & Insurance Co., Inc. v. Limcaco and Tagaytay-Taal Tourist Dev't Corporation v. Court of Appeals.
Petitioner Eastern Heights asserted that the municipal tax delinquency sale was null and void because the local government of Taytay, Rizal, failed to comply with the mandatory requirements under Section 254 and Section 258 of Republic Act No. 7160, specifically by failing to serve a notice of levy, demand for payment, or deed of conveyance on Petitioner Eastern Heights.
Petitioner Eastern Heights maintained that the jurisdictional deposit requirement under Section 267 of Republic Act No. 7160 is inapplicable because the deposit is only required in actions initiated by a taxpayer to annul a tax sale, and not when the taxpayer merely sets up the invalidity of the tax sale as an affirmative defense in a post-registration proceeding initiated by a purchaser.

B. Respondent / Defense (Respondent Tagumpay Realty Corporation)

Respondent Tagumpay argued that the amendment of the petition from "Eastern Heights Investments" to "Eastern Heights Investments and Development Corporation" was a mere formal correction of a clerical or typographical error, which was permissible as a matter of right because Petitioner Eastern Heights had not filed any responsive pleading.
Respondent Tagumpay contended that the Regional Trial Court sitting as a land registration court acquired jurisdiction over the person of Petitioner Eastern Heights because Petitioner Eastern Heights voluntarily appeared by filing a motion to dismiss that sought affirmative reliefs other than the mere dismissal of the petition for lack of personal jurisdiction.
Respondent Tagumpay asserted that the Regional Trial Court is vested with full and general jurisdiction under Section 2, Section 75, and Section 107 of Presidential Decree No. 1529 to resolve both non-controversial and highly contentious issues in land registration and post-registration proceedings, thereby avoiding multiplicity of suits and simplifying registration proceedings.
Respondent Tagumpay maintained that the Regional Trial Court and the Court of Appeals correctly refused to entertain the challenge of Petitioner Eastern Heights to the validity of the tax sale because Petitioner Eastern Heights failed to deposit with the court the purchase price plus interest as mandatorily required under Section 267 of Republic Act No. 7160.

C. Common Ground

The adversarial parties did not stipulate to any common ground regarding the validity of the tax sale or the ownership of the subject property. However, both Petitioner Eastern Heights and Respondent Tagumpay recognized that the subject property was originally registered under Transfer Certificate of Title No. 285425 in the name of Petitioner Eastern Heights, and that Respondent Tagumpay purchased the subject property at a tax delinquency sale on February 9, 2012.

IV. Issues

A. Main Issue

B. Secondary Issues

Whether the Regional Trial Court acquired jurisdiction over the person of Petitioner Eastern Heights Investments and Development Corporation despite the failure of Respondent Tagumpay Realty Corporation to serve summons on Petitioner Eastern Heights under the correct corporate name in the original petition.
Whether Petitioner Eastern Heights Investments and Development Corporation can validly challenge the validity of the tax delinquency sale in a post-registration proceeding without complying with the jurisdictional deposit requirement set forth in Section 267 of Republic Act No. 7160.

V. Ruling / Disposition

A. MAIN ISSUE: YES. The Supreme Court dismissed the petition and affirmed the Court of Appeals Decision because the Regional Trial Court is fully vested with jurisdiction. Under Section 2 of Presidential Decree No. 1529, the historical distinction between the general jurisdiction of the Regional Trial Court and the limited, summary jurisdiction of the Regional Trial Court when acting merely as a land registration or cadastral court was completely eliminated. Consequently, the Regional Trial Court has full authority to hear, determine, and resolve all questions, including contentious and substantial issues like the validity of a tax delinquency sale, in post-registration proceedings filed under Section 75 and Section 107 of Presidential Decree No. 1529.
B. SECONDARY ISSUES:
1. YES. The Supreme Court affirmed that the Regional Trial Court acquired jurisdiction over the person of Petitioner Eastern Heights because Petitioner Eastern Heights voluntarily submitted to the jurisdiction of the Regional Trial Court. By filing a Voluntary Special Appearance and Urgent Motion to Dismiss that raised substantive defenses and sought the nullification of the tax delinquency sale, and by actively participating in the subsequent proceedings, filing briefs, and seeking affirmative reliefs, Petitioner Eastern Heights waived any defect in the service of summons under Section 20, Rule 14 of the then Rules of Court.
2. NO. The Supreme Court affirmed that the Regional Trial Court cannot entertain any challenge to the validity of the tax delinquency sale because compliance with Section 267 of Republic Act No. 7160 is a mandatory jurisdictional prerequisite. Since Petitioner Eastern Heights failed to deposit with the court the amount for which the subject property was sold plus interest, the challenge of Petitioner Eastern Heights to the tax sale was legally ineffective, and the tax sale remained valid and binding.

Verbatim Dispositive Portion

"WHEREFORE, the petition is DENIED. The Decision dated November 7, 2017 and the Resolution dated July 11, 2018 of the Court of Appeals in CA-G.R. CV No. 107794 are hereby AFFIRMED."

VI. Ratio Decidendi and Doctrines

A. Ratio Decidendi

The Plenary Jurisdiction of the Regional Trial Court under Section 2 of Presidential Decree No. 1529: Under Section 2 of Presidential Decree No. 1529, the Regional Trial Court is vested with exclusive original jurisdiction over all applications for original registration of title to lands and over all petitions filed after original registration of title, with power to hear and determine all questions arising upon such applications or petitions.
Elimination of the General vs. Limited Jurisdiction Distinction: The enactment of Presidential Decree No. 1529 completely eliminated the distinction between the general jurisdiction of the Regional Trial Court and the limited jurisdiction formerly conferred upon the Regional Trial Court when acting merely as a cadastral or land registration court. The legislative intent behind this change was to avoid multiplicity of suits and simplify registration proceedings by conferring upon the Regional Trial Court the authority to resolve both non-controversial and highly contentious or substantial issues in a single proceeding.
Abandonment of the Summary Doctrine in Post-Registration Incidents: Prior to the effectivity of Presidential Decree No. 1529, summary reliefs under Section 112 of Act No. 496, such as an action to compel the surrender of an owner's duplicate certificate of title, could only be granted if there was complete unanimity among the parties or no adverse claim. However, under Section 2 of Presidential Decree No. 1529, the land registration court is no longer fettered by this summary limitation. The court is fully authorized to decide contentious issues, and the old doctrines in Alto Surety & Insurance Co., Inc. v. Limcaco and Tagaytay-Taal Tourist Dev't Corporation v. Court of Appeals, which barred land registration courts from resolving controversial matters, are completely abandoned.
Jurisdiction over Post-Registration Petitions under Sections 75 and 107: Under Section 75 and Section 107 of Presidential Decree No. 1529, a purchaser of registered land at a public auction, such as a tax delinquency sale, may petition the Regional Trial Court to compel the surrender of the owner's duplicate certificate of title for the purpose of registering the transfer. If the registered owner refuses or fails to surrender the duplicate title, the Regional Trial Court, in the exercise of the Regional Trial Court's broad jurisdiction under Section 2, is fully authorized to order the cancellation of the outstanding owner's duplicate title and direct the issuance of a new transfer certificate of title in the name of the purchaser.
Jurisdictional Deposit Requirement under Section 267 of Republic Act No. 7160: Section 267 of Republic Act No. 7160, otherwise known as the Local Government Code of 1991, provides a mandatory jurisdictional requirement that no court shall entertain any action assailing the validity of a tax sale at public auction unless the taxpayer deposits with the court the amount for which the real property was sold plus interest. This deposit requirement is a condition precedent that applies whenever the validity of a tax sale is challenged, whether through a direct complaint or as an defense or opposition to a petition for surrender of title under Presidential Decree No. 1529. The failure of the taxpayer to make this deposit deprives the court of the authority to hear or resolve any challenge to the validity of the tax sale.
Acquisition of Jurisdiction over the Person via Voluntary Appearance: Under Section 20, Rule 14 of the then applicable Rules of Court, a defendant's voluntary appearance in an action is equivalent to the service of summons. Although a special appearance to challenge the court's jurisdiction over the person does not constitute voluntary submission, the inclusion of other grounds or substantive defenses, such as a prayer to nullify a tax sale, and the subsequent active participation of the party in the trial, appeal, and filing of briefs, constitutes a waiver of any defect in the service of summons and vests the Regional Trial Court with full personal jurisdiction.

B. Doctrines/Rules

1. Jurisdiction Over Post-Registration Petitions

Section 2 of Presidential Decree No. 1529 provides:

"Courts of First Instance [now Regional Trial Courts] shall have exclusive jurisdiction over all applications for original registration of title to lands, including improvements and interests therein, and over all petitions filed after original registration of title, with power to hear and determine all questions arising upon such applications or petitions."

2. Surrender of Withheld Duplicate Title

Section 107 of Presidential Decree No. 1529 provides:

"SECTION 107. Surrender of Withheld Duplicate Certificates. — Where it is necessary to issue a new certificate of title pursuant to any involuntary instrument which divests the title of the registered owner against his consent or where a voluntary instrument cannot be registered by reason of the refusal or failure of the holder to surrender the owner's duplicate certificate of title, the party in interest may file a petition in court to compel surrender of the same to the Register of Deeds. The court, after hearing, may order the registered owner or any person withholding the duplicate certificate to surrender the same, and direct the entry of a new certificate or memorandum upon such surrender. If the person withholding the duplicate certificate is not amenable to the process of the court, or if not any reason the outstanding owner's duplicate certificate cannot be delivered, the court may order the annulment of the same as well as the issuance of a new certificate of title in lieu thereof. Such new certificate and all duplicates thereof shall contain a memorandum of the annulment of the outstanding duplicate."

3. Mandatory Deposit in Tax Sale Challenges

Section 267 of Republic Act No. 7160 provides:

"No court shall entertain any action assailing the validity of any sale at public auction of real property or rights therein under this Title until the taxpayer shall have deposited with the court the amount for which the real property was sold, together with interest of two percent (2%) per month from the date of sale to the time of the institution of the action."

C. Limitations/Exceptions

No Reopening of Original Decrees: While Section 2 and Section 108 of Presidential Decree No. 1529 grant the Regional Trial Court broad jurisdiction to hear contentious cases, this authority is strictly limited and does not extend to the reopening of the original decree of registration. The land registration court cannot review or set aside the original judgment that brought the land under the Torrens system.
Protection of Innocent Purchasers for Value: The power of the court to alter, amend, or cancel a certificate of title under Section 108 of Presidential Decree No. 1529 is subject to the strict limitation that nothing shall be ordered or done by the court which will impair the title or other interest of a purchaser holding a certificate for value and in good faith, or the heirs and assigns of the purchaser, without the written consent of the purchaser or the heirs and assigns of the purchaser.
