G.R. No. L-24426 July 25, 1974
ROSALINA Z. TIONGCO, petitioner, vs. GUILLERMO DE LA MERCED and RITA VENERACION, respondents.

FACTS

Petitioner Rosalina Z. Tiongco sought to reverse a decision of the Court of Appeals which sustained the lower court’s denial of her petition for review of a cadastral decree covering Lots 1838 and 1856 of the Sta. Rosa Cadastre. The Court of Appeals found that Tiongco and other claimants were deprived of their rights without due process of law due to the fraudulent machinations of a deputy clerk of court. Despite this finding of a fatal procedural infirmity, the appellate court ruled against Tiongco.
The Court of Appeals determined that respondents Guillermo de la Merced and Rita Veneracion were innocent purchasers for value of the subject lots. Consequently, the court held that even if the underlying cadastral decree was void for lack of due process, the rights of these innocent purchasers, who relied on the Torrens titles subsequently issued, were protected under the law. This finding presented the central legal obstacle to Tiongco’s petition for review.

ISSUE

Whether a decree of registration, rendered void due to a denial of procedural due process, can be reviewed and set aside when an innocent purchaser for value has subsequently acquired an interest in the property.

RULING

The Supreme Court affirmed the decision of the Court of Appeals, ruling that the petition for review could not prosper due to the presence of an innocent purchaser for value. The Court anchored its decision on the doctrine established in Vda. de Cuaycong v. Vda. de Sengbengco, which draws a critical distinction between voidable decrees obtained by fraud and void decisions rendered without due process.
The legal logic is clear: while a decision suffering from a fatal infirmity like lack of due process is void and may generally be attacked, the law provides a specific statutory exception to protect the stability of registered titles. Section 38 of the Land Registration Act allows a petition for review of a decree based on fraud within one year from its entry, but expressly conditions this remedy by stating “provided no innocent purchaser for value has acquired an interest.” The Court in Cuaycong explicitly extended this same protective condition to petitions seeking review on the ground of denial of due process. The rationale is to balance the need for justice to a deprived party with the imperative of protecting those who have acquired property in good faith and for value, relying on the indefeasibility of a Torrens title. This protection is fundamental to the Torrens system’s objective of ensuring certainty in land ownership.
The Court further held that it could not overturn the factual finding of the Court of Appeals that respondents were innocent purchasers for value. The Supreme Court’s jurisdiction is limited to reviewing errors of law; it is not its function to re-examine or weigh the evidence on this factual matter already conclusively determined by the appellate court. Therefore, with the existence of an innocent purchaser for value established as a fact, the statutory bar under Section 38 of the Land Registration Act became operative, rendering the petition for review unavailing.
