Mistake of Law vs Mistake of Fact: Grounds for Relief from Judgment in the Philippines

---

A party who loses a case because of a mistaken belief about the law may have no remedy. The Supreme Court has long held that the "mistake" that justifies relief from a final judgment refers to a mistake of fact, not of law. This principle was reaffirmed in Philadelphia Agan v. Heirs of Sps. Andres Nueva and Diosdado Nueva (G.R. No. 155018, December 11, 2003), a case that also clarified the application of Article 1606 of the Civil Code on the right of redemption.

The case arose from a pacto de retro (sale with right to repurchase) of a parcel of land in Cagayan de Oro City. The vendors, Spouses Nueva, sold the property to Philadelphia Agan for P21,000.00, with a six-month right to repurchase. They failed to redeem within the period.

Years later, Agan filed a petition for consolidation of ownership. The trial court ruled in her favor, consolidating ownership in her name. However, the dispositive portion also granted the vendors thirty days from receipt of the decision to repurchase the property, citing Articles 1606 and 1607 of the New Civil Code.

Agan did not appeal. She believed the redemption clause was surplusage and unenforceable. Instead, she filed a petition for relief from judgment under Rule 38 of the Rules of Court, asking the court to delete that portion of the decision. The trial court granted her petition, but the Court of Appeals reversed, and the Supreme Court affirmed the appellate court's ruling.

The Issue: What Kind of Mistake Justifies Relief?

The central question was whether Agan's belief that the redemption clause was surplusage constituted a mistake under Rule 38. The Court answered no.

Rule 38, Section 1 of the Rules of Court allows relief from judgment when the judgment was entered through fraud, accident, mistake, or excusable negligence. The Court clarified that the mistake contemplated by the rule is one of fact, not of law.

Why Agan's Mistake Was Not Enough

Agan argued that she did not appeal because she believed the redemption clause was unenforceable. The Court rejected this reasoning, citing the old case of Guevara v. Tuason & Co. (1 Phil. 27 [1901]).

The Court explained that a party's erroneous opinion about the correctness of a judicial decision does not confer a right to relief. If a party believes a judgment is wrong, the proper remedy is to appeal. A mistake of law—even one made in good faith—does not prevent a party from filing an appeal. As the Court put it, the law helps the vigilant, but not those who sleep on their rights.

The Court also noted that Agan's inaction was telling. If she truly believed the clause was surplusage, she would have moved to correct it immediately—not only after the vendors offered to repurchase the property. Her failure to file a motion for reconsideration or an appeal within the reglementary period meant she accepted the trial court's judgment.

The Court's Application of Article 1606

The Court also addressed Agan's argument that the trial court erred in granting the vendors a redemption period under Article 1606 of the Civil Code.

Article 1606, third paragraph, provides that a vendor may repurchase within thirty days from the time final judgment was rendered in a civil action, on the basis that the contract was a true sale with right to repurchase. This provision applies when the vendor honestly believed, in good faith, that the transaction was actually an equitable mortgage.

The Court found that the vendors had raised this defense in good faith. They alleged that the sale price of P21,000.00 was far below the fair market value of P81,320.00, that they remained in possession of the property, and that they continued paying real estate taxes. The trial court made no finding of bad faith on their part. Therefore, they were entitled to the protection of Article 1606.

Interestingly, the Court noted that the trial court erred in granting thirty days from receipt of the decision. The law says thirty days from the time final judgment was rendered—meaning the judgment must first become final and executory. However, this error was moot because the vendors had already consigned the redemption price within the period fixed.

Practical Takeaways

• Mistake of fact, not law, justifies relief. A party who misinterprets a court decision or the law cannot use Rule 38 as a second chance after losing the right to appeal.
• Appeal is the remedy for legal errors. If a party believes a judgment is wrong, the proper course is to file a motion for reconsideration or an appeal within the reglementary period.
• Rule 38 is an equitable remedy. It is granted only in exceptional cases, such as fraud, accident, mistake of fact, or excusable negligence. It is not a substitute for a lost appeal.
• Article 1606 protects good-faith vendors. A vendor who honestly believed a pacto de retro sale was actually an equitable mortgage may repurchase the property within thirty days from final judgment.
• Read the entire decision, not just the dispositive portion. The Court noted that the alleged inconsistency in the RTC decision was only apparent when read together with the body of the decision and the cited legal provisions.
