De La Paz vs. L & J Development Company

No monetary interest is due on a loan unless the stipulation to pay interest has been expressly reduced to writing, and a stipulated interest rate of 6% per month (72% per annum) on a loan with no specified maturity is unconscionable and void regardless of which party proposed the rate, such that interest payments made under the void stipulation must be returned to the borrower through the principle of solutio indebiti or applied against the principal via legal compensation.

Rolando C. De la Paz, an architect, extended a loan to L & J Development Company, a property developer then developing Brentwood Subdivision in Antipolo, whose President and General Manager was Atty. Esteban Salonga. The loan was unsecured and had no specified maturity date. The interest rate of 6% per month was allegedly proposed by L&J through its secretary/treasurer, Arlene San Juan, on the representation that the loan was short-term. The dispute arose when L&J ceased paying interest due to financial difficulties, prompting Rolando to file a collection suit.

On December 27, 2000, Rolando C. De la Paz lent ₱350,000.00 without any security to L & J Development Company, a property developer headed by Atty. Esteban Salonga as President and General Manager. The loan carried no specified maturity date and was agreed to bear interest at 6% per month, equivalent to ₱21,000.00 monthly. Rolando had no prior communication with Atty. Salonga but knew of him as a lawyer, son of a former Senator, and owner of L&J, which developed Brentwood Subdivision in Antipolo where Rolando's associate Nilo Velasco resided. When Nilo informed Rolando that L&J needed money to finish its projects, Rolando agreed to lend the amount. The terms were negotiated through Arlene San Juan, L&J's secretary/treasurer, who stated the money would finance L&J's housing project. Rolando claimed it was L&J and Atty. Salonga, through Arlene, who insisted on paying the 6% monthly interest, representing the loan as short-term.

From December 2000 to August 2003, L&J paid Rolando a total of ₱576,000.00 in interest charges across thirty payments, an amount exceeding the ₱350,000.00 principal. L&J ceased paying when it suffered financial difficulties attributed to the economic crisis. Rolando alleged that as of January 2005, L&J's debt inclusive of monthly interest stood at ₱772,000.00, and that Atty. Salonga had tricked him into parting with his money without the loan transaction being reduced to writing.

L&J and Atty. Salonga acknowledged the loan as a corporate debt but attributed non-payment to a fortuitous event — financial difficulties from the economic crisis. They argued that the 6% monthly interest was unconscionable and shocking to morals, and that the payments already made should be applied to the ₱350,000.00 principal. The MeTC upheld the interest rate on estoppel grounds but reduced it to 12% per annum for equity, a ruling affirmed by the RTC. The CA reversed, holding that no interest was due under Article 1956 for lack of a written stipulation and that the 6% monthly rate was unconscionable, applying legal compensation to set off the ₱350,000.00 principal against the ₱576,000.00 in interest payments and ordering Rolando to return the ₱226,000.00 excess.

• Blame on Borrower's Legal Knowledge: Rolando argued that Atty. Salonga, a lawyer, took advantage of his legal knowledge to hoodwink Rolando into believing no written document was necessary to reflect the interest rate, and that had Atty. Salonga advised him the stipulation should be in writing, he would have readily assented.
• Interest Proposed by Borrower: Rolando maintained that the 6% monthly interest rate could not be unconscionable because it was not imposed by the creditor but was in fact offered by the borrower, who dictated all the terms of the loan, distinguishing the case from jurisprudence protecting helpless borrowers from predatory lenders.
• No "Enslavement" of Borrower: Rolando contended that the case does not fall under the scenario of enslaving the borrower or causing the hemorrhaging of his assets that courts seek to prevent when invalidating unconscionable interest rates.
• Estoppel: Rolando asserted that L&J was estopped from questioning the interest rate, having voluntarily paid it for more than two and a half years.

• Mutual Agreement on Rate: L&J countered that the interest rate was subject to negotiation and agreed upon by both parties, not by the borrower alone.
• Jurisprudence on Unconscionable Rates: L&J argued that jurisprudence has nullified interest rates on loans of 3% per month and higher as contrary to morals and public interest, and that the 6% monthly rate falls squarely within this rule.
• Question of Fact: L&J averred that Rolando's imputation of bad faith on Atty. Salonga's part raised a question of fact, which cannot be raised under Rule 45.

• Written Stipulation Requirement: Whether the lack of a written stipulation for the payment of interest bars the creditor from collecting monetary interest under Article 1956 of the Civil Code.
• Unconscionability of Interest Rate: Whether a 6% monthly interest rate (72% per annum) on a loan with no specified maturity is unconscionable and void, regardless of which party proposed the rate.
• Application of Excess Payments: Whether the interest payments made by the borrower under the void stipulation should be returned or applied against the principal obligation.

• Written Stipulation Requirement: Yes. No interest is due because the parties did not reduce their agreement to pay interest in writing, as required by Article 1956 of the Civil Code; estoppel cannot validate an act prohibited by law.
• Unconscionability of Interest Rate: Yes. A 6% monthly interest rate on a loan with no specified period is unconscionable, iniquitous, and void, regardless of whether it was the borrower who proposed the rate; voluntariness does not make an unconscionable interest stipulation valid.
• Application of Excess Payments: Yes. The excess interest payments must be returned to the borrower through the principle of solutio indebiti, and legal compensation applies to set off the principal against the total interest paid, leaving the lender liable to return the excess of ₱226,000.00.

• Written Stipulation Requirement: Article 1956 of the Civil Code provides that no interest shall be due unless it has been expressly stipulated in writing. Jurisprudence requires two conditions for interest to be due: (a) express stipulation for the payment of interest, and (b) the agreement is reduced to writing. Here, it was undisputed that the parties did not put their agreement in writing, so no interest was due. Rolando's claim that Atty. Salonga duped him into foregoing a written document was rejected; the Court found no deception, noting that L&J devotedly paid interest for over two years and stopped only due to financial difficulties, and that Rolando, an educated architect, could have insisted on a written contract. The Court emphasized that courts cannot constitute themselves guardians of persons who are not legally incompetent. As to estoppel, the Court cited Ching vs. Nicdao, holding that estoppel cannot give validity to an act prohibited by law or against public policy; thus, L&J's voluntary payments did not validate the void interest stipulation.

• Unconscionability of Interest Rate: While the Usury Law was suspended by Central Bank Circular No. 905, courts retain the power to equitably reduce unreasonable interest rates. Stipulated interest rates of 3% per month and higher have consistently been declared excessive, iniquitous, unconscionable, and exorbitant, and void for being contrary to morals. The Court clarified that such rates are invalidated only where loan terms are open-ended and interest is applied for an indefinite period — as in this case, where no specified maturity existed, making 6% monthly or 72% per annum "definitely outrageous and inordinate." The fact that the borrower proposed the rate did not exempt it from invalidation; citing Asian Cathay Finance and Leasing Corporation vs. Gravador, the Court held that the imposition of an unconscionable interest rate is immoral and unjust even if knowingly and voluntarily assumed, and voluntariness does not make the stipulation valid.

• Application of Excess Payments: Since no monetary interest was due under Article 1956, the CA correctly adjudged that the excess interest payments made by L&J should be applied to its principal loan. As computed by the CA, the ₱576,000.00 in total interest payments, set off against the ₱350,000.00 principal, left an excess of ₱226,000.00 which Rolando was bound to return to L&J following the principle of solutio indebiti under Article 2154 of the Civil Code. The interest rate on this returnable amount was modified from 12% to 6% per annum pursuant to Central Bank Circular No. 799, which took effect on July 1, 2013.

• Written Stipulation for Interest (Article 1956) — No interest shall be due unless it has been expressly stipulated in writing. Two conditions must concur: (a) express stipulation for the payment of interest, and (b) the agreement to pay interest is reduced in writing. Absent either, no monetary interest may be collected. Estoppel cannot give validity to an act prohibited by law or against public policy.

• Unconscionable Interest Rates — Stipulated interest rates of 3% per month and higher are excessive, iniquitous, unconscionable, and exorbitant, and are void for being contrary to morals, if not against the law. This doctrine applies where loan terms are open-ended and interest rates are applied for an indefinite period. The unconscionability of a rate is not affected by which party proposed it; even if the borrower knowingly and voluntarily assumed the rate, the stipulation remains void. Voluntariness does not make an unconscionable interest stipulation valid.

• Legal Compensation (Article 1279) — Where the creditor and debtor become mutually indebted to each other (here, Rolando owed return of excess interest payments while L&J owed the principal), legal compensation may apply if the requisites of Article 1279 are met: (1) each obligor is bound principally and is a principal creditor of the other; (2) both debts consist in a sum of money; (3) both debts are due; (4) they are liquidated and demandable; and (5) neither is subject to retention or controversy commenced by third persons.

• Solutio Indebiti (Article 2154) — If something is received when there is no right to demand it, and it was unduly delivered through mistake, the obligation to return it arises. Applied here to require Rolando to return the excess interest payments collected under a void stipulation.

• "No interest shall be due unless it has been expressly stipulated in writing." — This is the text of Article 1956 of the Civil Code, cited at the opening of the decision and serving as the primary statutory basis for barring Rolando's collection of interest.

• "Estoppel cannot give validity to an act that is prohibited by law or one that is against public policy." — This principle, quoted from Ching vs. Nicdao, was applied to reject the argument that L&J's voluntary payment of interest for over two years estopped it from questioning the rate, reinforcing that voluntary performance cannot cure a legal prohibition.

• "The imposition of an unconscionable rate of interest on a money debt, even if knowingly and voluntarily assumed, is immoral and unjust. It is tantamount to a repugnant spoliation and an iniquitous deprivation of property, repulsive to the common sense of man." — Quoted from Asian Cathay Finance and Leasing Corporation vs. Gravador, this passage establishes that the identity of the party proposing the rate is immaterial to the determination of unconscionability.

• "Courts cannot follow one every step of his life and extricate him from bad bargains, protect him from unwise investments, relieve him from one-sided contracts, or annul the effects of foolish acts. Courts cannot constitute themselves guardians of persons who are not legally incompetent." — Quoted from Vales vs. Villa, this passage was applied to reject Rolando's claim that Atty. Salonga's legal expertise should have compelled him to ensure a written stipulation, affirming that a competent creditor bears responsibility for safeguarding his own interests.

• Central Bank Circular No. 799, s. 2013 — Took effect July 1, 2013; set the rate of interest for loans or forbearance of money and the rate allowed in judgments, in the absence of express contract, at 6% per annum. Applied to modify the interest on the ₱226,000.00 returnable excess from 12% to 6% per annum.
