Case Summary (G.R. No. 168940)

Factual Background

The Tans (Angelina and Ruben) executed the Kasulatan to secure a P30,000 loan with a six-month maturity and a contractual compound interest rate of 5% per month. After Ruben’s death, Angelina failed to pay on maturity. Petitioners demanded an accumulated total of P359,000. Petitioners then extrajudicially foreclosed the mortgage on February 5, 1999, became the sole bidder at auction, obtained consolidation of title after the redemption period lapsed, and were given possession through a writ of possession and sheriff’s ejectment.

Initial Court Action (RTC)

On September 26, 2000, respondents filed a Complaint for Nullification of Mortgage and Foreclosure and/or Partial Rescission of Documents and Damages in the Regional Trial Court (RTC) of Malolos, alleging the interest rate was unconscionable. On June 11, 2002, the RTC held the Kasulatan could not be wholly declared void but partially rescinded the iniquitous interest provision, reducing interest to 12% per annum and awarding an additional 1% per month as liquidated damages from February 17, 1994 to June 21, 2000; it also mentioned an offer by respondents to redeem for P200,000 but denied moral damages and attorney’s fees.

Court of Appeals Decision

The Court of Appeals affirmed the RTC’s finding that the stipulated 5% monthly compounded interest was iniquitous and equitably reduced it to the legal rate of 12% per annum. The appellate court further held that, in the interest of equity and substantial justice, respondents could redeem the mortgaged property notwithstanding the statutory redemption period’s expiration.

Issues Raised Before the Supreme Court

Petitioners advanced three principal contentions: (1) the Court of Appeals improperly nullified an interest rate agreed to voluntarily by the parties; (2) the appellate court unlawfully modified the contract, effectively making a new contract between parties; and (3) the extension of the redemption period violated Act No. 3135’s one-year rule.

Petitioners’ Argument on Freedom of Contract and Interest Ceilings

Petitioners relied on Central Bank Circular No. 905 (s. 1982), which suspended the statutory usury ceiling effective January 1, 1983, arguing lenders and borrowers may validly agree to any interest rate and that the courts lacked authority to nullify an expressly stipulated compounded interest term.

Respondents’ Argument on Unconscionability and Public Policy

Respondents countered that contractual terms are binding only to the extent they are not contrary to law, morals, good customs, public order, or public policy, and asserted that the 5% monthly compounded interest is excessive, immoral, and therefore void under Article 1306 of the Civil Code.

Supreme Court’s Governing Legal Principles

The Court reiterated that while freedom of contract is recognized, it is not absolute and is subject to Article 1306’s limitation that stipulations contrary to law, morals, good customs, public order, or public policy are invalid. The Central Bank Circular did not confer license to impose unconscionable rates that would enslave borrowers or strip them of assets. Precedent was cited where iniquitous rates were struck down (Medel, Ruiz, Solangon) and where more moderate rates were upheld (Bautista, Garcia).

On Unconscionability of the Stipulated Rate

Applying the foregoing principles and controlling precedents, the Court held the contractual 5% monthly compounded interest (60% per annum) to be excessive, iniquitous, unconscionable, and contrary to morals and Article 1306, and therefore void ab initio. The void stipulation is treated as never having existed; the underlying debt must be considered without that iniquitous interest provision.

Substitution by the Legal Interest Rate and Effect on the Contract

Because the iniquitous term was void, the Court imposed the legal interest rate of 12% per annum in substitution, consistent with prior decisions (e.g., Medel, Ruiz). The Court emphasized this is not a unilateral rewriting of the contract but an application of legal principle that void contractual terms must yield and be replaced by lawful standards where necessary to determine the proper debt.

Liquidated Damages Award

The Court addressed the additional 1% per month liquidated damages previously awarded by the RTC. Article 2226 requires an agreement between parties to establish liquidated damages. The Kasulatan contained no stipulation for liquidated damages, and none was proven. Therefore, the award for 1% per month as liquidated damages had no legal basis and was deleted.

Foreclosure, Redemption, and Equity

Because the foreclosure sale rested on an overstated outstanding balance inflated by the void iniquitous interest, the Court found the foreclosure proceedings conducted on March 3, 1999 could not stand. Citing Heirs of Zoilo Espiritu v. Landrito, the Court held that where debtors were not given a reasonable opportunity to pay the correct amount (i.e., principal plus lawful interest), foreclosure cannot properly be maintained and the resulting registration cannot transfer valid title. Accordingly, the foreclosure was nullified; the registration of the sale could not vest title in petitioners.

Redemption Period and Act No. 3135

Although Act No. 3135 provides a one-year statutory redemption period, the Court determined the extension or allowance of redemption was unnecessary to analyze separately because nullification of the foreclosure rendered the statutory redemption issue
