The Supreme Court’s decision in Development Bank of the Philippines v. Ruben S. Go and Angelita M. Go addresses the critical issue of unilateral interest rate increases by lending institutions. The court affirmed that while stipulated interest rates are valid, unilateral increases without notice or legal basis are void. This ruling protects borrowers from arbitrary adjustments to their loan terms, ensuring transparency and fairness in lending practices, and highlights the importance of adhering to contractual obligations and due process in financial transactions.

Interest Rate Roulette: When Banks Can’t Change the Rules Mid-Game

The case revolves around a loan obtained by Ruben and Angelita Go from the Development Bank of the Philippines (DBP) in 1982. The loan, amounting to ₱494,000.00, was secured by a mortgage on the Go spouses’ properties. The loan agreement stipulated an 18% per annum interest rate. However, DBP subsequently increased the interest rate without prior notice to the Gos, first to 35%, then to 29%, and finally to 30%. When the Gos defaulted on their loan, DBP foreclosed on their properties. The Gos then filed a suit to nullify the foreclosure, arguing that the interest rate increases were unlawful.

The central legal question was whether DBP had the right to unilaterally increase the interest rates on the loan. The Regional Trial Court (RTC) initially sided with the Gos, declaring the interest and penalty charges imposed by DBP as null and void. On appeal, the Court of Appeals (CA) reversed the RTC’s decision, upholding the validity of the promissory notes and the real estate mortgage. However, the CA also declared the increases in interest rate as null and void, ruling that these were done without notice and without a valid Monetary Board increase in lending rates. DBP then filed a petition for review with the Supreme Court, seeking a modification of the CA’s decision to include penalty charges and insurance premiums in the computation of the total amount due.

The Supreme Court partly granted DBP’s petition. The Court emphasized that while a stipulated interest rate is generally valid, any subsequent increases must be done with proper notice and in accordance with the law. The Court cited its earlier rulings on the matter, affirming that unilateral increases in interest rates violate the principle of mutuality of contracts. The principle of mutuality of contracts, as enshrined in Article 1308 of the Civil Code, dictates that a contract must bind both contracting parties; its validity or compliance cannot be left to the will of one of them. The Court explained this concept using the following quote:

“The DBP further reserves the right to increase, with notice to the mortgagor, the rate of interest on the loan as well as other fees and charges on loans and advances pursuant to such policy as it may adopt from time to time during the period of the loan. Provided, that the rate of interest on the loan shall be reduced in the event that the applicable maximum rate of interest is reduced by law or by the Monetary Board; Provided, further, that the adjustment in the rate of interest shall take effect on or after the effectivity of the increase or decrease in the maximum rate of interest.”

Building on this principle, the Supreme Court found that DBP’s unilateral increases of the interest rates were indeed invalid, as these violated the principle of mutuality of contracts. The Court agreed with the CA’s ruling that the extrajudicial foreclosure was premature because the loan had not yet matured at the time of the foreclosure proceedings. However, the Supreme Court also clarified that the Gos were obligated to pay the insurance premiums and other charges as stipulated in the mortgage contract. The Court emphasized that obligations arising from contracts have the force of law between the contracting parties and should be complied with in good faith, citing Article 1159 of the Civil Code. The court underscores the need to honor contractual obligations, reinforcing the stability and predictability of financial agreements.

The Supreme Court distinguished the penalty charge from the interest rate, explaining that a penalty clause is an accessory obligation designed to ensure the performance of the principal obligation. However, the Court ruled that the penalty charge was not applicable in this case because the Gos’ non-performance was due to the unauthorized increases in interest rates by DBP. Since the CA invalidated DBP’s unilateral increases in interest rates, the Supreme Court ruled that the private respondents had no obligation to pay the increased rate. Therefore, the obligation to pay the 8% penalty charge never arose since there was, as yet, no breach that would put the penalty clause in operation.

The Supreme Court also addressed DBP’s request to include a writ of execution for judicial foreclosure in the dispositive portion of the decision. The Court denied this request, stating that DBP had initially opted for extrajudicial foreclosure, which was later declared void by both the RTC and the CA. The Court clarified that DBP still had the option to resort to either judicial or extrajudicial foreclosure if the Gos defaulted on their obligation, but it must follow the proper procedure in Rule 68 of the Rules of Court if it chooses judicial foreclosure. The Court also stated that it could not allow the petitioner to resort to short-cuts in the procedure for judicial foreclosure even in the guise of avoiding multiplicity of suits through the mere expediency of amending a duly-promulgated decision of the appellate court.

The implications of this decision are significant for both borrowers and lending institutions. For borrowers, it reinforces their right to fair and transparent lending practices. Lending institutions must adhere to contractual obligations and cannot unilaterally change the terms of the agreement without proper notice and legal basis. The decision also clarifies the distinction between interest rates and penalty charges, emphasizing that penalty charges are only applicable when there is a breach of contract due to the debtor’s fault. It promotes fairness and equity in financial transactions, protecting borrowers from predatory lending practices and ensuring that lending institutions act responsibly.
