Republic vs. Heirs of Ignacio Daquer

The mere issuance of a homestead patent does not convert unclassified public land into alienable and disposable agricultural land; a positive act of the Executive expressly declassifying inalienable public land is required prior to disposition.

Ignacio Daquer applied for a homestead patent in 1933 over a 9-hectare parcel in Bacuit, Palawan. The application was approved in 1936, and Original Certificate of Title No. G-3287 was issued. Following Daquer's death in 1969, an investigation by the Community Environment and Natural Resource Office in 2000 revealed that the land fell within an "Unclassified Zone" per Land Classification Map No. 1467, indicating it was public forest land never declared alienable or disposable.

• The Homestead Application: On October 22, 1933, Ignacio Daquer filed Homestead Application No. 197317 with the Bureau of Lands for a 9-hectare parcel (Lot No. H-19731) in Bacuit, Palawan, for his exclusive personal use and benefit.

• Approval and Registration: On September 3, 1936, the Provincial Environment and Natural Resources Officer approved the application and issued Homestead Patent No. V-67820 covering 65,273 square meters. The patent was transmitted to the Register of Deeds, and Original Certificate of Title No. G-3287 was issued in Daquer's name.

• Death of Patentee and Investigation: Daquer died on April 3, 1969, survived by his children Porcepina Daquer Aban, Alita Daquer Quijano, and Neria Daquer Laguta. In 2000, acting on instructions to inventory suspected spurious titles in timberland areas, Land Management Officer Mariano Lilang, Jr. investigated and certified that the land was "still within the Unclassified Zone" based on Land Classification Map No. 1467 certified in 1941, meaning it was public forest land never declared alienable or disposable.

• Complaint for Reversion: On April 1, 2003, the Republic filed a Complaint for Cancellation of Free Patent, Original Certificate of Title and Reversion, alleging the Director of Lands lacked jurisdiction over unclassified public forest land and that possession could not ripen into ownership without prior classification.

• Trial Court Ruling: The Regional Trial Court denied the complaint, ruling that unclassified lands are presumed agricultural under Krivenko v. Register of Deeds and that the issuance of the patent effectively classified the land as alienable and disposable.

• Appellate Proceedings: The Court of Appeals affirmed, holding that the patent issuance was equivalent to an official proclamation classifying the land as alienable.

• Positive Act Requirement: The Republic maintained that only the President, upon recommendation of the DENR Secretary, can classify public lands into alienable or disposable through a positive, express act such as a proclamation or presidential decree. The mere issuance of a homestead patent by the Director of Lands does not constitute such classification.
• Jurisdictional Defect: The Director of Lands possessed no jurisdiction to issue a patent over unclassified public forest land. The patent and title were void ab initio because the land was inalienable at the time of application.
• Presumption of State Ownership: Citing Heirs of Spouses Vda. De Palanca v. Republic, the Republic argued that unclassified lands remain inalienable public domain, and possession, however long, cannot ripen into private ownership without a positive act of declassification.
• Distinction from Chavez: The Republic distinguished Chavez v. Public Estates Authority, noting that case involved specific presidential decrees (PD 1084 and 1085) and a special patent transferring reclaimed lands, whereas the instant case involved only the Public Land Act, which merely provides procedure for administering already-classified lands.

• Presumption of Regularity: The Heirs argued that the President, acting through the Undersecretary of Agriculture and Natural Resources, would not have approved the homestead patent over forest land, invoking the presumption of regularity of official functions.
• Presumption of Agricultural Character: Citing Krivenko v. Register of Deeds, respondents contended that unclassified lands are presumed agricultural (not timber or mineral) and thus alienable.
• Patent as Classification: Invoking Chavez v. Public Estates Authority, respondents argued that the Public Land Act coupled with the issuance of Homestead Patent No. V-67820 was equivalent to an official proclamation classifying the land as alienable and disposable.

• Classification by Patent: Whether the mere issuance of a homestead patent could classify an otherwise unclassified public land into alienable and disposable agricultural land of the public domain.
• Jurisdictional Validity: Whether the issuance of Homestead Patent No. V-67820 was jurisdictionally defective as Lot No. H-19731 was still part of inalienable public land when the application was granted.

• Classification by Patent: No. The issuance of a homestead patent does not automatically classify unclassified public land as alienable and disposable. Under Section 6 of Act No. 2874, the exclusive prerogative to classify public lands belongs to the President (formerly Governor-General), requiring a positive, express act such as an official proclamation or decree directly intended to declassify the land. The Director of Lands may only dispose of lands already officially classified as alienable.
• Jurisdictional Validity: Yes. Because the land was unclassified public forest at the time of application—having never been declared alienable by positive act—the Director of Lands lacked jurisdiction to issue the patent. The patent and consequent title are void ab initio.
• Inapplicability of Indefeasibility: The rule that certificates of title based on homestead patents become indefeasible after one year does not apply where the land covered is inalienable public domain. Citing Agne v. Director of Lands and Republic v. Ramos, an action for reversion lies at any time and is not barred by the statute of limitations.
• State Not Estopped: The State cannot be estopped by the mistake or error of its officials or agents in erroneously awarding patents over inalienable lands. The land reverts to the public domain ipso jure.

• Positive Act Requirement — Lands of the public domain can only be classified as alienable and disposable through a positive act of the government (such as an official proclamation, presidential decree, or legislative act) expressly declassifying inalienable public land. The burden of proving alienability rests on the applicant.
• Void Patents over Inalienable Lands — A certificate of title issued pursuant to a homestead patent over land that is inalienable public domain is void ab initio. The rule on indefeasibility of title after one year under Section 103 of PD 1529 does not apply to void patents issued without jurisdiction.
• State Immunity from Estoppel — The State is not bound by the errors or omissions of its agents in granting patents over lands not disposable by law. It may institute reversion actions at any time.

• "A positive act declaring land as alienable and disposable is required. In keeping with the presumption of State ownership, the Court has time and again emphasized that there must be a positive act of the government, such as an official proclamation, declassifying inalienable public land into disposable land for agricultural or other purposes."
• "The mere issuance of a homestead patent does not automatically remove the land from inalienability and convert it into alienable agricultural land."
• "The rule on the incontrovertibility of a certificate of title upon the expiration of one year... does not apply where an action for the cancellation of a patent and a certificate of title issued pursuant thereto is instituted on the ground that they are null and void because the Bureau of Lands had no jurisdiction to issue them at all."
• "The State cannot be estopped by the omission, mistake, or error of its officials or agents."

• Secretary of the Department of Environment and Natural Resources v. Yap, 589 Phil. 156 (2008) — Controlling precedent on the positive act requirement for classification of public lands.
• Chavez v. Public Estates Authority, 433 Phil. 506 (2002) — Distinguished; involved specific presidential decrees transferring reclaimed lands, not mere procedural statutes.
• Heirs of Spouses Vda. De Palanca v. Republic, 531 Phil. 602 (2006) — Cited for the rule that unclassified lands remain inalienable and possession cannot ripen into ownership.
• Krivenko v. Register of Deeds, 79 Phil. 461 (1947) — Distinguished; addressed the definition of agricultural land for constitutional purposes, not the conversion of unclassified land via administrative patent.
• Agne v. Director of Lands, 261 Phil. 13 (1990) — Applied for the rule that indefeasibility does not apply to void patents issued without jurisdiction.
• Republic v. Ramos, 117 Phil. 45 (1963) — Cited for the rule that the State may file reversion actions at any time and is not barred by prescription.

• Act No. 2874 (Public Land Act), Sections 6, 7, 8, 9, 11 — Vested exclusive authority to classify public lands in the President; required official classification before disposition.
• Presidential Decree No. 1529 (Property Registration Decree), Section 103 — Provided that certificates of title pursuant to patents become indefeasible after one year, subject to the land being disposable.
• 1987 Constitution, Article XII, Section 2 — Declared that all lands of the public domain belong to the State and that alienable lands are limited to agricultural lands.
