Polotan, Sr. vs. Court of Appeals

An escalation clause in a contract of adhesion that ties interest rate adjustments to prevailing market rates is valid and not violative of the principle of mutuality of contracts, provided the adjustment is not left solely to the will of one party. The Court held that because the clause allowed interest rates to fluctuate based on market conditions—a factor beyond the creditor's control—it was not potestative and provided leeway for de-escalation.

Rodelo G. Polotan, Sr., a lawyer and businessman, applied for and obtained a Diners Club credit card in October 1985. The application form, a contract of adhesion prepared by Security Diners International Corporation, stipulated that unpaid balances would earn interest at 3% per annum plus the prime rate of Security Bank and Trust Company. It further contained an escalation clause authorizing Security Diners to increase interest rates correspondingly in the event of changes in prevailing market rates, without need of notice other than posting on the monthly statement. By May 8, 1987, Polotan had incurred aggregate credit charges, interest, and service charges amounting to P33,819.84.

• The Credit Application: Petitioner Rodelo G. Polotan, Sr. applied for a Diners Club credit card in October 1985. The application form contained terms and conditions governing credit accommodations, including a provision that unpaid balances would earn 3% interest per annum plus the prime rate of Security Bank & Trust Company. The contract also contained an escalation clause stating that if prevailing market rates changed, the new interest rate would be the guiding rate without need of notice other than posting on the monthly statement, and authorizing Security Diners to increase interest rates and charge additional service fees as necessary. Ofricano Canlas signed as a joint and several guarantor.
• The Unpaid Obligation: As of May 8, 1987, Polotan incurred total credit charges, interest, and service charges amounting to P33,819.84. Demands for payment proved futile, prompting Security Diners to file a collection suit.
• The Supplementary Card Issue: During the proceedings, Polotan presented a Diners Club Monthly Statement for his wife, Alicia Polotan, dated February 8, 1989, which showed a zero balance. Polotan argued this was a judicial admission that his wife's account was fully paid. Security Diners presented witness Alfredo Vicente, who explained that the zero balance resulted from a new policy effective February 1989, which consolidated supplementary card accounts under the principal cardholder's statement rather than issuing separate statements.
• Lower Court Findings: The trial court found Polotan liable for the full amount and rejected his defenses. The Court of Appeals affirmed these factual findings, noting that Polotan, a lawyer and businessman, could not claim to have entered the contract blindfolded, and that the zero balance statement was not proof of payment but a result of account consolidation.

• Petitioner argued that the interest rate provision was obscure, ambiguous, and not susceptible of reasonable interpretation, particularly the terms "prime rate," "prevailing market rate," and "guiding rate." Because the contract was one of adhesion, any ambiguity should be resolved against the party who caused it.
• Petitioner contended that the escalation clause was illegal for violating Central Bank Circulars, asserting that while it allowed for the escalation of interest, it did not allow for a downward adjustment of the same.
• Petitioner maintained that Security Diners's statement of account showing a zero balance for his wife constituted a judicial admission that she had no more account with the company. To contradict this admission, Security Diners should have laid the proper basis by declaring it a result of a palpable mistake under Section 4, Rule 129 of the Rules of Court.
• Petitioner claimed he should have been awarded damages due to Security Diners's bad faith.

• Respondent Security Diners argued that the contract was valid and binding, and that the escalation clause was tied to prevailing market rates rather than its sole discretion, thus complying with the principle of mutuality.
• Respondent countered that the zero balance on the supplementary cardholder's statement was not a judicial admission of payment but a result of the new policy of consolidating accounts, as explained by its witness Alfredo Vicente.
• Respondent maintained that the factual findings of the lower courts, which found the obligation due and demandable, were conclusive and not subject to review by the Supreme Court.

• Procedural Issues: Whether the factual findings of the trial court, as affirmed by the Court of Appeals, are subject to review by the Supreme Court.
• Substantive Issues: Whether the escalation clause in the credit card contract is void for being obscure, one-sided, or violative of the principle of mutuality of contracts and Central Bank Circulars. Whether a statement of account showing a zero balance for a supplementary cardholder constitutes a judicial admission of payment that cannot be contradicted without laying a basis for palpable mistake.

• Procedural: The Court declined to review the factual findings, holding that such findings of the trial court, when adopted and confirmed by the Court of Appeals, are final and conclusive and may not be reviewed on appeal. None of the recognized exceptions to this rule were found to exist, as the lower courts' conclusions were logically arrived at and substantially supported by the evidence.
• Substantive: The Court upheld the validity of the escalation clause. While the contract was one of adhesion, the Court noted that petitioner, a lawyer and businessman, could not claim ignorance of its terms. The clause was not dependent solely on the creditor's will because it was tied to prevailing market rates, which are beyond the creditor's control. The provision allowing interest to be based on prevailing market rates inherently provided leeway for de-escalation. Regarding the judicial admission, the Court held that a statement of account showing a zero balance was not a judicial admission of payment. It was equivocal and satisfactorily explained by the creditor's witness as a result of account consolidation. The proper evidence of payment would have been a receipt, which petitioner failed to present.

• Contracts of Adhesion — A contract of adhesion is one in which one party imposes a ready-made form on the other, who may accept or reject it but cannot modify it. While ambiguities in such contracts are construed against the drafter, they are binding as ordinary contracts because the adhering party is free to reject them entirely. Courts may disregard their terms if the attendant facts show they are obviously too one-sided or unconscionable.
• Mutuality of Contracts — The binding effect of agreements is premised on mutuality based on the parties' essential equality. Any stipulation left solely to the will of one party is invalid. Escalation clauses are valid stipulations in commercial contracts to maintain fiscal stability, provided they are based on reasonable and valid grounds beyond the control of the parties, such as prevailing market rates, and are not solely potestative.
• Judicial Admissions — Admissions made by the parties in the pleadings or in the course of trial do not require proof and can be contradicted only if shown to have been made through palpable mistake. However, a statement of account showing a zero balance is not a conclusive judicial admission of payment; it is equivocal and can be explained by the issuing party.

• "Escalation clauses are valid stipulations in commercial contracts to maintain fiscal stability and to retain the value of money in long term contracts."
• "[T]he unilateral determination and imposition of increased interest rates by the herein respondent bank is obviously violative of the principle of mutuality of contracts ordained in Article 1308 of the Civil Code."
• "One party prepares the stipulation in the contract, while the other party merely affixes his signature or his 'adhesion' thereto, giving no room for negotiation and depriving the latter of the opportunity to bargain on equal footing."
• "Although said exhibit would, by itself, show that Mrs. Polotan had no more account with Diners Club, it would not have been conclusive to prove that said account was already paid. The proper evidence would have been a receipt of payment."

• Reyes v. CA, 258 SCRA 651 (1996) — Cited as controlling precedent for the rule that factual findings of the trial court, affirmed by the Court of Appeals, are final and conclusive and may not be reviewed on appeal, subject to recognized exceptions.
• Philippine Commercial International Bank v. CA, 255 SCRA 299 (1996) — Cited for the definition of a contract of adhesion and the principle that courts are not precluded from ruling out blind adherence to terms if they are obviously too one-sided.
• Almeda v. CA, 256 SCRA 292 (1996) — Cited for the principle of mutuality of contracts, holding that stipulations left solely to the will of one party are invalid.
• People v. Dizon, 260 SCRA 851 (1996) — Cited for the validity of escalation clauses in commercial contracts and the allowance of interest rates stipulated by the parties under Central Bank Circular 905.
• Florendo v. CA, 265 SCRA 678 (1996) — Cited for the proposition that the unilateral determination and imposition of increased interest rates violates the principle of mutuality of contracts.

• Article 1308, Civil Code — The Court applied this provision to invalidate conditions dependent solely on the will of one party, but found the escalation clause valid because it was tied to market rates, not the creditor's sole will.
• Section 2, Rule 129, Rules of Court — The Court interpreted this provision on judicial admissions, holding that a statement of account showing a zero balance was not a conclusive admission of payment and could be contradicted by the party that issued it.
• Central Bank Circular 905 — The Court noted that the stipulated interest rate was allowed under this Circular, which suspended the Usury Law, and that petitioner failed to cite any specific provision violated by the contract.
