Heirs of Reyes vs. Republic

The State is not estopped by the mistakes or illegal acts of its agents from assailing a void judgment, particularly when sovereign functions and environmental protection are involved.

Spouses Casiano Sandoval and Luz Marquez applied for registration of a 15,303-hectare lot in Isabela in 1961. After an order of general default, a compromise agreement was submitted in 1981 by the applicants, other private claimants, and the Directors of the Bureau of Lands and Bureau of Forest Development, distributing the land among themselves and the government bureaus. The Regional Trial Court approved the agreement and adjudicated the portions, including an 892-hectare share assigned to petitioners' predecessor as attorney's fees. The Office of the Solicitor General filed a petition for annulment of judgment eighteen years later, alleging lack of jurisdiction.

• Application for Registration: On July 17, 1961, spouses Casiano Sandoval and Luz Marquez applied for registration of Cadastral Lot 7453 (15,303.5928 hectares) in Cordon, Isabela, docketed as LRC Case No. II-N-36. Philippine Cacao and Farm Products, Inc. opposed the application, claiming ownership over a portion.
• Compromise Agreement: On March 30, 1962, the trial court issued an order of general default against the whole world except the Republic. Nearly 20 years later, on March 3, 1981, the heirs of Sandoval, other private claimants, and the Directors of the Bureau of Lands and Bureau of Forest Development submitted a compromise agreement. The provincial fiscal of Nueva Vizcaya represented the government bureaus.
• RTC Judgment: Judge Andres B. Plan approved the agreement, distributing the land as follows: 1,750 hectares to the Bureau of Lands; 5,661 hectares to the Bureau of Forest Development; 1,000 hectares to private heirs; 4,000 hectares to Philippine Cacao; and 2,892.5928 hectares to the Sandoval heirs. The Sandoval heirs assigned 892.5928 hectares to Atty. Jose C. Reyes as attorney’s fees.
• Annulment Proceedings: On August 18, 1999, the OSG filed a petition for annulment of judgment under Rule 47, alleging lack of jurisdiction. Petitioners moved to dismiss, arguing the OSG had participated and the petition was barred by laches and estoppel. The CA denied the motions and annulled the RTC decision, citing the unconstitutional adjudication of forest land, lack of evidence of ownership, and lack of OSG consent to the compromise agreement.

• Rule 47 Inapplicability: Petitioners argued that the Court of Appeals erred in giving due course to the petition for annulment under Rule 47 because land registration cases are not covered by the rule.
• Laches and Estoppel: Petitioners maintained that the Republic was estopped and barred by laches from challenging the judgment, citing the 18-year delay and the OSG's alleged participation in the initial hearing and subsequent manifestation withdrawing its appearance.
• Evidentiary Basis: Petitioners contended that the Court of Appeals erred in finding the decision was based solely on the compromise agreement without evidence of ownership.

• Rule 47 by Analogy: Respondent countered that Rule 47 applied by analogy due to the absence of a remedy under PD 1529.
• Lack of OSG Participation: Respondent argued that the OSG was never notified, never deputized the provincial fiscal to enter into the compromise agreement, and never received a copy of the judgment until 1998, precluding estoppel.
• Void Judgment: Respondent maintained that the RTC lacked jurisdiction because the land was forest land, rendering the judgment void.

• Annulment of Judgment: Whether the Court of Appeals correctly gave due course to the petition for annulment of judgment under Rule 47 despite the case being a land registration proceeding.
• Estoppel and Laches: Whether the Republic is estopped or barred by laches from challenging the RTC decision due to the lapse of 18 years and the alleged participation or withdrawal of the OSG.

• Annulment of Judgment: The petition for annulment was properly given due course. At the time of the application in 1961, the contested land was part of the public forest, reclassified as alienable only in 1979. Where the land applied for is part of the public forest, the land registration court acquires no jurisdiction. Procedural infirmities are immaterial when the court lacks jurisdiction, and environmental consequences override technicalities and rules of procedure.
• Estoppel and Laches: The Republic is not estopped. The State is not estopped by the mistakes or errors of its officials or agents, especially when performing sovereign functions. The Directors of Lands and Forest Development lacked authority to enter into the compromise agreement, and the OSG's alleged withdrawal—assuming it occurred—constituted an unconscionable dereliction of duty. Illegal acts of government agents do not bind the State, and the Government is never estopped from questioning the acts of its officials, more so if they are erroneous or irregular.

• Doctrine of Non-Estoppel of the State — The State, as represented by the government, is not estopped by the mistakes, errors, or illegal acts of its officials or agents, especially when its actions are sovereign in nature. Applied to hold that the unauthorized compromise agreement entered into by the Directors of Lands and Forest Development, and the OSG's alleged withdrawal, cannot bind the Republic to lose nearly 8,000 hectares of forest land.
• Jurisdiction over Forest Lands — A land registration court acquires no jurisdiction over land that is part of the public forest. Applied to render the RTC decision void ab initio, as the land in question was forest land at the time the application was filed in 1961.

• "Where the land applied for is part of the public forest, the land registration court acquires no jurisdiction over it."
• "The Government is never estopped from questioning the acts of its officials, more so if they are erroneous, let alone irregular."
• "This Court will never allow unscrupulous government agents, whether retired or incumbent, to bind the Republic to unconscionable and illegal agreements with questionable characters to the detriment of the national interest."

• Republic v. Sayo, G.R. No. 60413 — Followed. Annulled a judgment based on a compromise agreement involving the same parties and adjacent land, due to lack of evidence of proprietary rights, lack of authority of Directors to compromise, and lack of OSG participation.
• Collado v. Court of Appeals, 439 Phil. 149 — Followed. Upheld the annulment of a land registration decision over a watershed reservation; established that environmental consequences override technicalities and rules of procedure.
• Sharp International Marketing v. Court of Appeals, G.R. No. 93661 — Followed. Held that the Government is never estopped from questioning the acts of its officials, more so if they are erroneous or irregular.
• Oposa v. Factoran, G.R. No. 101083 — Cited. Emphasized the constitutional right to a balanced and healthful ecology and the correlative duty to refrain from impairing the environment.

• Rule 47, Rules of Court — Applied by analogy to allow the petition for annulment of judgment due to the absence of a specific remedy under PD 1529 for the government to assail a void land registration judgment.
• Presidential Decree No. 1529 (Property Registration Decree) — Noted as lacking a specific remedy for the government to annul a void judgment in land registration cases.
• Presidential Decree No. 478, Sec. 1(e) — Cited for the exclusive authority of the OSG to represent the government in land registration and related proceedings, rendering the provincial fiscal's unauthorized representation invalid.
• Section 16, Article II, 1987 Constitution — Cited as the constitutional basis for the State's duty to protect and advance the right of the people to a balanced and healthful ecology.
