Co vs. Philippine National Bank

The governing principle is that the law in force at the time the mortgage contract was executed and the extrajudicial foreclosure was initiated governs the right of redemption, and subsequent legislative enactments that would alter the redemption terms to the detriment of the contracting parties cannot be applied retroactively due to the constitutional prohibition against the impairment of contracts. Where strict statutory application would result in an unconscionable windfall to the debtor, the Court may invoke the principle of unjust enrichment under the Civil Code to require full satisfaction of the secured obligation, thereby balancing statutory redemption rights with equitable considerations.

Standard Parts Manufacturing Corporation secured loans from the Philippine National Bank in 1961 and 1963, executing real estate mortgages over properties in Baguio City and Makati to secure a loan subsequently increased to P1,000,000.00. The mortgage contract contained a clause expressly incorporating Republic Act No. 1300, the then PNB Charter, and Act No. 3135 for extrajudicial foreclosure proceedings. Following Standard’s default, PNB extrajudicially foreclosed the mortgaged properties in 1974 and purchased them as the highest bidder. Before the expiration of the statutory redemption period, Standard assigned its right of redemption over the Makati property to Citadel Insurance & Surety Co., Inc. Citadel subsequently tendered payment based on the foreclosure bid price plus statutory interest, which PNB rejected in favor of a higher amount representing Standard’s total outstanding indebtedness.

• On November 10, 1961, and February 20, 1963, Standard Parts Manufacturing Corporation executed real estate mortgages over properties in Baguio City and Makati in favor of PNB to secure a loan that was subsequently increased to P1,000,000.00. The mortgage contract contained a clause expressly incorporating Republic Act No. 1300, the PNB Charter, and Act No. 3135, as amended, to govern foreclosure proceedings.
• Following Standard’s default, PNB extrajudicially foreclosed the Baguio properties and attached chattels on July 19, 1974, and the Makati property on August 8, 1974, emerging as the highest bidder in both sales. The corresponding certificates of sale were issued and subsequently registered.
• On February 20, 1976, Standard executed a Deed of Assignment transferring its right of redemption over the Makati property to Citadel Insurance & Surety Co., Inc. On March 5, 1976, Citadel wrote to PNB tendering P1,621,970.00 as the redemption price, computed as the foreclosure bid price plus one percent monthly interest. PNB rejected the tender, asserting that the correct redemption amount was P3,366,546.42, representing Standard’s total outstanding indebtedness.
• On March 11, 1976, Citadel filed the instant action, depositing the manager’s check with the trial court subject to its control. The parties stipulated that the case involved pure questions of law, including the timeliness of redemption, the applicable redemption amount, the validity of the tender, and the enforceability of the assignment. The trial court ruled for Citadel, prompting PNB’s direct appeal.

• Petitioner maintained that the redemption was timely exercised within the statutory period from the registration of the certificate of sale, and that the tender was valid despite PNB’s refusal to accept the manager’s check.
• Petitioner argued that Act No. 3135 and Sections 29 to 34 of Rule 39 of the Rules of Court governed the redemption, limiting the required payment to the purchaser’s bid price, statutory interest, and any taxes or assessments paid by the purchaser.
• Petitioner contended that applying the subsequently enacted P.D. No. 694 would unconstitutionally impair the contractual obligations of the parties, and that the assignment of the right of redemption to Citadel and subsequently to Leticia Co was legally enforceable despite lack of registration.

• Respondent countered that Section 25 of P.D. No. 694, the new PNB Charter, governed the redemption and required payment of the mortgagor’s entire indebtedness as a condition for the release of the foreclosed property.
• Respondent argued that the tender of P1,621,970.00 was legally insufficient and therefore invalid, and that the assignment of redemption rights to Citadel and subsequently to Leticia Co was not binding on the bank absent proper registration.
• Respondent maintained that strict adherence to its charter and the mortgage contract mandated full satisfaction of the outstanding obligation prior to the transfer of title.

• Procedural Issues: Whether the assignment of the right of redemption, absent registration under Article 1625 of the Civil Code, was binding on the mortgagee, and whether the direct appeal to the Supreme Court was proper under the applicable statute.
• Substantive Issues: Whether the redemption was exercised within the reglementary period; whether Act No. 3135 and Rule 39 or P.D. No. 694 governs the redemption amount; whether the tender of payment via manager’s check was valid and effective; and whether the principle of unjust enrichment warrants modification of the statutory redemption price to prevent unconscionable enrichment of the debtor.

• Procedural: The Court held that the assignment of the right of redemption was valid and binding on PNB. Registration of the assignment is not strictly required to bind the mortgagee, particularly where no prejudice or damage to the bank was demonstrated and the bank failed to timely object to the assignee’s personality during the tender. The direct appeal was properly entertained as a matter of right under Republic Act No. 5440.
• Substantive: The Court ruled that the redemption was timely, as the tender was made on March 5, 1976, within one year from the registration of the certificate of sale. Applying Act No. 3135 and Rule 39, the statutory redemption price comprised only the bid price plus interest and taxes. However, the Court declined to apply P.D. No. 694 retroactively, holding that its application would violate the constitutional prohibition against the impairment of contracts, as the mortgage was executed under the old PNB Charter which incorporated Act No. 3135. To prevent unjust enrichment of the debtor at the bank’s expense, the Court invoked Articles 22 and 2142 of the Civil Code. It modified the trial court’s judgment to require the petitioner to pay the bank’s full outstanding obligation of P3,366,546.42 as of March 11, 1976, without additional interest, subject to adjustments for interest earned on the consigned funds and the bank’s retention of property rentals.

• Non-Impairment of Contracts — The Constitution prohibits legislation that retroactively alters the terms of existing contracts to the detriment of either party. The Court held that P.D. No. 694 could not govern the redemption because the mortgage contract was executed in 1963 under Republic Act No. 1300, which expressly incorporated Act No. 3135. Applying a subsequent law to increase the redemption burden would unconstitutionally impair the contractual obligations established under the prior legal regime.
• Unjust Enrichment and Quasi-Contract — Articles 22 and 2142 of the Civil Code prevent a party from acquiring or retaining a benefit at another’s expense without just or legal ground. The Court applied these provisions to modify the strictly statutory redemption amount, reasoning that limiting the bank’s recovery to the bid price plus interest would unconscionably enrich the debtor, given the substantial disparity between the foreclosure bid and the actual outstanding debt.
• Liberal Construction of Redemption Laws — Redemptions are favored in law, and statutes governing them are construed liberally to enable debtors to recover their property and satisfy multiple creditors. The Court emphasized that a liberal approach aligns with banking policy, which prioritizes loan recovery over asset acquisition.

• "To alter those terms in a manner prejudicial to the mortgagor or the person redeeming the property as his successor-in-interest after the foreclosures and sales would definitely come within the constitutional proscription against impairment of the obligations of contracts." — The Court utilized this principle to reject the retroactive application of P.D. No. 694, emphasizing that contractual terms incorporated by reference remain binding despite subsequent legislative changes.
• "It strikes Us as rather unconscionable that by a literal application of the law and perhaps due to a mistake in the amount of the bid made by PNB, the bank would not get full satisfaction of its credit. Indeed, there would be unjust enrichment on the part of the debtor-mortgagor in such an eventuality. Our sense of justice cannot permit such inequitous advantage." — This passage justified the Court’s invocation of quasi-contract to require full payment of the outstanding obligation, balancing statutory redemption rights with equitable fairness.
• "Redemptions are looked upon with favor, and when an injury is to follow, a liberal construction will be given to our redemption laws to the end that the property of the debtor may pay as many of the debtor's liabilities." — The Court reaffirmed this policy to support allowing the redemption while ensuring the secured creditor is not unfairly prejudiced by a low foreclosure bid.

• Medina v. Philippine National Bank, 56 Phil. 655 — Cited to distinguish the requirement of full debt payment from the bid price. The Court clarified that Medina applied to a mortgage executed before Act No. 3135 took effect, where the bank’s right to demand full payment was undisputed, reinforcing the non-impairment principle.
• Nepomuceno v. RFC, G.R. No. L-14877, Nov. 23, 1960 — Distinguished because the case involved a special charter provision for the Rehabilitation Finance Corporation that expressly required full indebtedness payment, which differed from the old PNB Charter governing the instant mortgage.
• DBP v. Mirang, 66 SCRA 141 — Distinguished on the same ground, as it upheld special charter provisions of the Development Bank of the Philippines that governed redemption, whereas the present case was bound by the contractual incorporation of Act No. 3135.
• Enage v. Vda. de Escano, 38 Phil. 687 — Relied upon to establish that a valid tender of redemption, once refused, need not be followed by judicial consignation to preserve the right, and no further interest accrues on the redemption money.
• Javellana v. Mirasol, 40 Phil. 761 — Applied to affirm that redemption by manager’s check is legally permissible and constitutes a valid tender of payment, defeating PNB’s challenge to the mode of tender.
• Lichauco v. Olegario, 43 Phil. 540 — Cited to uphold the validity of the assignment of the right of redemption, confirming that execution debtors may legally transfer such rights and that lack of registration does not invalidate the assignment absent prejudice to the mortgagee.

• Section 6, Act No. 3135, as amended by Act No. 4018 — Governs the one-year redemption period in extrajudicial foreclosures and establishes the procedural framework for the exercise of the right of redemption.
• Sections 29, 30, and 34, Rule 39 of the Rules of Court — Detail the procedure and computation for redemption, specifying payment of the purchase price plus one percent monthly interest and any taxes or assessments paid by the purchaser.
• Section 20, Republic Act No. 1300 (Old PNB Charter) — Referenced as the governing charter at the time of contract execution, which contemplated judicial foreclosure and was contractually supplemented by Act No. 3135 for extrajudicial proceedings.
• Section 25, Presidential Decree No. 694 (New PNB Charter) — Contrasted with the old charter; held inapplicable due to non-retroactivity and the constitutional prohibition against impairing existing contracts.
• Articles 22 and 2142, Civil Code — Invoked to prevent unjust enrichment and establish a quasi-contractual obligation requiring the redeemer to pay the full outstanding debt to avoid unconscionable windfall.
• Article 13, Civil Code — Referenced regarding the computation of months and years, specifically addressing the distinction between “one year” and “twelve months” for the redemption period.
• Section 11, Article IV, 1973 Constitution — Cited as the constitutional basis for prohibiting the retroactive application of P.D. No. 694 to an existing mortgage contract.
• Republic Act No. 5440 — Provided the statutory basis for the direct appeal to the Supreme Court.
