Applicable Law and Constitutional Basis
Applicable Constitution: 1987 Philippine Constitution (decision rendered after 1990).
Relevant statutory and decisional authorities relied upon in the analysis: Civil Code provisions on quasi-contracts (Art. 2154–2156), contract of lease (Arts. 1657, 1659), prescriptive statutes (Art. 1144 — actions on written contracts, ten-year prescription; Art. 1145(2) — quasi-contracts, six-year prescription), interruption of prescription by extrajudicial written demand (Art. 1155), and jurisprudence interpreting accrual of causes of action against the government (Español v. Board of Administrators, Philippine Veterans Administration and related cases).
Facts and Trial Court Ruling
DPRC alleged that MIAA imposed increased rentals pursuant to Resolution No. 98-30 and Administrative Order No. 1 without the contractually required prior notice and without valid administrative procedure, and that such resolutions were later judicially declared void. DPRC paid the increased rentals under protest from December 11, 1998 until December 5, 2005, totaling P9,593,179.87 in alleged overpayments. DPRC demanded a refund in writing on July 27, 2006 and filed suit in December 2008. The RTC ruled for DPRC, awarding the full amount claimed plus legal interest at 12% per annum from the date of extrajudicial demand, attorney’s fees, and costs.
Court of Appeals’ Rationale and Adjustment
The CA affirmed liability but characterized DPRC’s claim as one grounded in the quasi-contract of solutio indebiti (restitution of undue payment). Applying Article 1145(2) of the Civil Code (six-year prescriptive period for quasi-contracts), the CA held that DPRC could only recover overpayments made within the six years immediately preceding the filing or demand. The CA therefore limited recovery to payments made between January 9, 2003 and December 5, 2005, totaling P3,839,643.05, reasoning that earlier payments (December 11, 1998 to December 5, 2002) were barred by prescription.
Central Issue Presented to the Supreme Court
Whether the CA correctly characterized DPRC’s cause of action as solutio indebiti (a quasi-contract) and therefore correctly applied the six-year prescription under Article 1145(2), resulting in reduction of recoverable amounts; or whether DPRC’s claim arises from breach of the written lease contract, entitling DPRC to relief under the ten-year prescriptive period of Article 1144 and permitting recovery of the full amount.
Supreme Court’s Analysis on the Nature of the Cause of Action
The Supreme Court examined the two-element test for solutio indebiti: (1) payment made when no binding relation exists between payor and recipient, and (2) payment made through mistake (not by liberality or other cause). The Court found both elements lacking:
Binding relation: DPRC and MIAA were in a lessor-lessee contractual relationship under the June 4, 1998 lease. The parties’ obligations and rental escalation provisions were governed by that written contract (including Section 2.06 requiring a valid Administrative Order and prior notice for price escalation). Where a contract governs the parties’ relation, a dispute respecting payments arising out of that relation is contractual in nature, not a quasi-contract. The Court relied on precedents holding that when payments arise from an existing contract (e.g., letter of credit or repurchase agreements), the cause is contractual and governed by the prescriptive period applicable to contracts.
Mistake: The Court concluded DPRC’s payments were not made by mistake of fact or law. DPRC consistently protested Resolution No. 98-30 (December 8, 1998) and paid the increased rates under protest and compulsion while the administrative action remained presumptively valid. The payments were deliberate compliance with an administrative measure presumed valid until judicially annulled. Solutio indebiti applies when a payment is made under the erroneous belief that it was due; that was not DPRC’s position. DPRC paid under protest because it had no judicial ruling at the time establishing the payments as undue.
Consequently, the Court held the cause of action to be contractual (breach of the lease and attendant statutory rights), not quasi-contractual.
Accrual of Cause of Action and Start of Prescription
The Court applied the established rule that, where an administrative policy or measure is presumptively valid, a cause of action to recover payments based on the policy accrues only when a court declares the administrative measure invalid. Citing Español v. Board of Administrators, the Court held that DPRC’s cause of action accrued on December 1, 2004, the date the Court in Airspan invalidated MIAA’s Resolution No. 98-30. Only from that date could DPRC assert with certainty that the administrative measure had no legal effect and that payments made pursuant to it were wrongful.
Correct Prescription Period and Effect of Extrajudicial Demand
Because DPRC’s cause of action is contractual, Article 1144’s ten-year prescriptive period for actions upon written contracts applies, not the six-year period for quasi-contracts. Even under either prescriptive scheme, the Court noted that an extrajudicial written demand interrupts prescription (Art. 1155) and causes the prescriptive period to run anew from receipt of the demand. DPRC made a written extrajudicial demand on July 27, 2006; that demand interrupted any prior lapse and started a new prescriptive period. Consequently, DPRC had until July 27, 2016 to file suit; the Complaint filed on December 23, 2008 was within that period. Thus no part of DPRC’s claim had prescribed as of the filing of suit.
Supreme Court’s Ho

- RTC rendered judgment in favor of DPRC on August 15, 2011; RTC later issued an Order dated November 17, 2011 clarifying the interest component.
- CA affirmed the RTC’s liability finding but reduced the recoverable amount by application of prescription based on solutio indebiti; DPRC moved for partial reconsideration of the CA decision, which was denied.
- MIAA filed a Comment on the Petition before the Supreme Court; DPRC filed a Reply. MIAA did not file a CA appeal from the CA’s decision and resolution.
Facts and Antecedent Proceedings
- DPRC and MIAA entered into a Contract of Lease dated June 4, 1998 covering: (a) a 1,631.12‑square‑meter parcel of land; and (b) a 630.88‑square‑meter building, both located at Domestic Road, Pasay City.
- Contractual monthly rental amounts: P75,357.74 for the land and P33,310.46 for the building; DPRC faithfully paid rentals pursuant to the lease.
- On April 2, 1998, MIAA passed Resolution No. 98‑30, effective June 1, 1998, which increased rentals of concessionaires and lessees; MIAA issued Administrative Order No. 1, Series of 1998 reflecting the new schedule of fees, charges, and rates.
- DPRC initially refused to pay the increased rentals, asserting the increase had been decreed without prior notice and hearing.
- On November 19, 1998, MIAA demanded payment of P655,031.13 representing rental arrears based on Resolution No. 98‑30 with 2% interest compounded monthly; after recomputation and deduction of P26,135.70, MIAA demanded P628,895.43.
- On December 8, 1998, DPRC formally protested the increased rentals and the computation, but indicated its intention to comply in good faith; on December 11, 1998, DPRC paid P628,895.43 based on the new rates, and continued paying the increased rates subsequently, often “under protest.”
- On December 1, 2004, the Supreme Court in Manila International Airport Authority v. Airspan Corporation, et al. (486 Phil. 1136, 2004) nullified Resolution Nos. 98‑30 and 99‑11 for failure to observe notice and hearing requirements.
- On December 21, 2005, DPRC advised MIAA of its intention to stop paying the increased rental rates; effective January 1, 2006 DPRC stopped paying the increased rate and reverted to the original rates in the lease.
- DPRC paid a total amount of P9,593,179.87 in excess of the stipulated monthly rentals for the period December 11, 1998 to December 5, 2005.
- On June 22, 2006, MIAA demanded P645,216.21 allegedly representing rental balance for January–June 2006; on July 27, 2006, DPRC replied denying the unpaid obligation and demanded refund of P9,593,179.87.
- MIAA ignored DPRC’s demand; DPRC sent a final written demand on November 5, 2008 and filed a Complaint for Collection of Sums of Money on December 23, 2008.
RTC Decision (Aug. 15, 2011) and Clarification (Nov. 17, 2011)
- RTC rendered judgment in favor of DPRC ordering MIAA to pay:
- The principal amount of P9,593,179.87;
- Legal interest (RTC’s disposi tive portion as originally penned later clarified);
- Attorney’s fees of P300,00.00 (noted in the record as “sic”);
- Costs of suit.
- On DPRC’s motion, RTC issued an Order dated November 17, 2011 clarifying the judgment to read: the principal amount of P9,593,179.87 plus 12% per annum legal interest computed from the time of the extrajudicial demand on July 27, 2006.
Court of Appeals Decision (May 31, 2013) and Rationale
- CA affirmed RTC’s finding of liability but modified the award: it reduced MIAA’s liability to P3,839,643.05, plus legal interest at 12% per annum computed from July 27, 2006.
- CA characterized the liability as arising from the quasi‑contract of solutio indebiti and applied the six‑year prescriptive period under Article 1145(2) of the Civil Code (actions upon quasi‑contract).
- CA reasoned the claim for refund must be commenced within six years from the date of payment; because DPRC demanded refund only on July 27, 2006 and filed suit on December 23, 2008, CA awarded only sums paid within six years prior to the demand (January 9, 2003 to December 5, 2005), totaling P3,839,643.05.
- CA concluded DPRC lost its right to recover P5,753,536.82 paid during December 11, 1998 to December 5, 2002 by reason of the six‑year prescriptive rule.
- DPRC’s Motion for Partial Reconsideration before the CA was denied by the assailed Resolution dated November 29, 2013.
Issue Presented to the Supreme Court
- Whether the CA correctly modified the RTC’s decision by reducing MIAA’s liability from the full amount of P9,593,179.87 to P3,839,643.05 on the basis that DPRC’s claim was governed by the six‑year prescriptive period applicable to quasi‑contracts (solutio indebiti).
Supreme Court Holding (March 27, 2019)
- The Petition for Review is GRANTED.
- The CA Decision dated May 31, 2013 and Resolution dated November 29, 2013 are PARTIALLY REVERSED and SET ASIDE insofar as the CA reduced MIAA’s liability to P3,839,643.05.
- The RTC Decision dated August 15, 2011, as clarified by its Order dated November 17, 2011, is REINSTATED.
- The Supreme Court held that DPRC is entitled to the full amount of P9,593,179.87 plus legal interest at 12% per annum computed from the time of extrajudicial demand on July 27, 2006.
- Decision authored by Justice Caguioa; concurred in by Carpio (Chairperson), Perlas‑Bernabe, J. Reyes, Jr., and Lazaro‑Javier, JJ.
Supreme Court Reasoning — Solutio Indebiti Not Applicable (Nature of the Cause of Action)
- The CA’s foundational premise — that the overpayments gave rise to a quasi‑contractual claim of solutio indebiti — is incorrect in the instant case.
- Civil Code Article 2154 (solutio indebiti) provides: where something is received when there is no right to demand it and it was unduly delivered by mistake, the obligation to return it arises.
- Two essential requisites for solutio indebiti: (1) payment made when there exists no binding relation bet
