- Trial court judgment: February 10, 1967.
- Supreme Court decision on appeal: July 31, 1970.
Applicable Law (including Constitutions and Rules)
- Applicable Constitution: 1935 Philippine Constitution (constitution operative at time of decision).
- Civil Code provisions: Article 1431 (estoppel), Article 1437 (elements of estoppel in pais), Article 1254 (application of payments), and general contract principles.
- Republic Act No. 529 (June 16, 1950) — prohibition on contractual stipulations requiring payment in foreign currency and rules on conversion for obligations incurred before the Act.
- Relevant Rules of Court: Rule 57 §1(f) (writ of attachment), Rule 33 (use of commissioners — Sections 11–12), Rule 131 §5 (presumptions), and related procedural provisions.
- Central Bank circulars (Circular Nos. 117, 121, 133) governing surrender and preferred vs. free market exchange rates.
Factual Background and Terms of the Agreement
- The parties contracted that appellee would render engineering design services (structural, electrical, mechanical, sanitary) for projects designed by appellant. Fee schedule was expressed as percentages of the architect’s fee: structural 12.5%, electrical 2.5%, mechanical 2.5%, sanitary 2.5%.
- The clarification to the proposal excluded certain services (e.g., foundation soil exploration; principally engineering works) and reserved appellee’s right to increase fees for small projects (cost < P100,000).
- Appellee performed engineering services on multiple projects (ten enumerated projects, including the International Rice Research Institute (IRRI) Research Center — the IRRI project).
Accounts, Payments and Dispute
- Appellee’s statement of account (Exh. 1-A) of December 11, 1961 aggregated engineering fees claimed at P116,565.00, showing prior payments of P57,000.00 and leaving a claimed balance of P59,565.00.
- Appellant contended that the correct balance was P10,861.08 and sent that amount (which appellee refused).
- Appellee sued asserting in the first cause of action unpaid fees in U.S. dollars ($28,000) (for the IRRI project) and Philippine pesos (P100,204.46), with admitted partial payments reducing the claimed balance. Additional causes of action sought consequential/moral damages and attorney’s fees; appellant denied liability and counterclaimed.
Procedural Posture — Commissioner and Trial Court
- The parties agreed that factual questions were to be resolved by a court‑appointed Commissioner. The Commissioner’s report concluded that appellee was entitled to $28,000 (20% of the $140,000 architect’s fee from the IRRI project) and P51,539.91 for the other projects, less prior payments of P69,475.46; recommended attorney’s fees of P5,000.
- At the hearing on the report, counsel for both parties stated they had no objection to the Commissioner’s findings of fact and limited the contested issues to two legal questions: (1) whether estoppel applied under the facts; and (2) whether the dollar amount could legally be paid in dollars or, if not, what exchange rate should govern conversion.
- Trial court judgment ordered defendant to pay P51,539.91 and $28,000 (the dollar amount to be converted into pesos at the current exchange rate at time of payment as certified by the Central Bank), with deduction of P69,475.46 already paid, legal interest from filing, and attorney’s fees of P8,000; defendant’s counterclaim dismissed.
Appellant’s Assignments of Error (summarized)
- Trial court erred by not holding appellee estopped by Exhibit 1-A (statement of account) from asserting amounts different from that exhibit.
- Trial court erred in directing the IRRI dollar balance to be converted at the rate at time of payment rather than at the official rate prevailing when appellant received his fee or at the official (P2:$1) rate.
- Trial court erred in not declaring that the aggregate balance due was only P15,792.05.
- Trial court erred in awarding attorney’s fees of P8,000 rather than the Commissioner’s recommended P5,000.
- Trial court erred in denying relief on appellant’s counterclaim.
Legal Issue Presented: Estoppel and Effect of Statement of Account
- The Commissioner found, and the parties did not dispute, that appellant did not rely on Exhibit 1‑A; appellee prepared Exh. 1‑A under mistake or ignorance and later corrected his position after consulting counsel. The trial court adopted these factual findings.
- Under Article 1431 (estoppel) and Article 1437 (elements of estoppel in pais), a party invoking estoppel must show reliance or action prompted by the representation. The Supreme Court reiterated that estoppel requires clear proof of all essential elements and that it is not favored where application would prevent a party from presenting the truth.
- The Court held that Exhibit 1‑A did not operate as an estoppel because (a) it was made under innocent mistake (the appellee’s ignorance) and (b) appellant did not lack knowledge of the true facts nor did he rely to his detriment on the statement; thus the essential elements of estoppel were not present.
- The Court further explained that a non‑judicial admission or a statement of account is prima facie evidence of correctness but is open to impeachment for mistake, error or fraud; appellee’s showing of mistake sufficed to overcome the prima facie effect.
- Practical construction by one party does not bind that party where the construction resulted from mistake and where allowing it would work an inequity; restitutionary remedies should be available rather than perpetuating a mistake.
Legal Issue Presented: Payment in Dollars and Applicable Exchange Rate
- Agreement entitled appellee to 20% of appellant’s IRRI fee, which equaled $28,000 (20% of $140,000). The Commissioner found that appellee had not been paid that $28,000 and recommended payment or its equivalent.
- Republic Act No. 529 declares void contractual provisions that require payment in a currency other than Philippine currency and provides conversion rules for obligations incurred prior to its enactment; RA 529 was enacted in 1950. The Court held RA 529 bars compelling payment in foreign currency and does not fix a conversion rate for obligations incurred after RA 529’s enactment.
- For obligations incurred after RA 529 (as here, obligation arose August 25, 1961), the Court applied the rule that conversion should be at the rate of exchange prevailing at the time of payment (endorsing Engel v. Velasco & Co. precedent and American authorities cited). Thus the trial court’s direction that $28,000 be converted at the current rate at time of payment (as certified by the Central Bank) was correct.
- The Court addressed appellant’s contention that the preferred official rate of P2:$1 applied on August 25, 1961: Central Bank Circular No. 121 (amending Circular No. 117) created distinctions between surrender at preferred vs. free market rates and the Court found that the $140,000 was not shown to be within the category mandating surrender at the preferred rate. In absence of proof, it was reasonable to presume the appellant converted at the free market (higher) rate; ordinary business practice supports the presumption that one will seek the most favorable exchange available.
- Finally, the Court rejected appellant’s argument that prior peso payments (aggregate P57,000) should be applied to the IRRI dollar obligation, because the Commissioner’s unchallenged factual finding was that no payment had been made in respect of the $28,000 account and the parties had agreed not to dispute the Commissioner’s factual findings.
Procedural and Evidentiary Rulings — Waiver of Challenges to Itemized Fees
- Appellant sought to re-litigate the correctness of many of the fee i
Case Syllabus (G.R. No. L-27782)
Procedural Posture
- Appeal from the decision dated February 10, 1967 of the Court of First Instance of Rizal (Branch V, Quezon City) in Civil Case No. Q-6561.
- Case brought directly to the Supreme Court raising only questions of law.
- During the appeal, appellee petitioned for a writ of attachment under Section 1(f) of Rule 57 Rules of Court; this Court, upon appellee’s posting of a P10,000 bond, issued the writ and ordered attachment of appellant’s estate in Rizal to value not less than P140,000 (Resolution June 3, 1969).
- Decision of trial court: judgment for plaintiff for P51,539.91 and $28,000.00 (with dollar amount to be converted at the current exchange rate at time of payment as certified by the Central Bank), less P69,475.46 paid, legal interest from filing of complaint, award of P8,000 attorney’s fees, costs; defendant’s counterclaim dismissed.

Statements of Account, Payments, and Disputed Balance
- December 11, 1961: appellee sent Exhibit “1” (letter) with attached itemized statement of account Exhibit “1-A”.
- Exhibit 1-A showed total engineering fees claimed by appellee of P116,565.00.
- Prior payments shown totalled P57,000.00, leaving claimed balance P59,565.00.
- Appellant’s May 18, 1962 resume of fees asserted appellee’s total due was P10,861.08.
- June 14, 1962: appellant sent appellee a check for P10,861.08; appellee refused to accept it as full payment.
- Commissioner and trial court findings: Commissioner recommended amounts due as $28,000.00 for IRRI (20% of $140,000 paid to appellant) and P51,539.91 for other projects, less P69,475.46 already paid by appellant; trial court adopted and rendered judgment consistent with the Commissioner’s recommendations except that it awarded P8,000 attorney’s fees.
Complaint, Causes of Action and Counterclaim
- Complaint filed August 10, 1962 containing four causes:
- First cause: claim for engineering fees — sums consisting of $28,000 (U.S.) and P100,204.46, excluding interest; alleged partial payment of P69,323.21 left unpaid $28,000 and P30,881.25.
- Second cause: claim P17,000 consequential and moral damages.
- Third cause: claim P55,000 as moral damages, attorney’s fees and litigation expenses.
- Fourth cause: claim P25,000 actual damages and attorney’s fees and litigation expenses.
- Appellant’s answer:
- Admitted appellee rendered services but asserted some services not in accordance with agreement; aggregate amount due only P80,336.29, of which P69,475.21 already paid, leaving P10,861.08.
- Denied liability for damages.
- Affirmative defenses: no cause of action; estoppel; premature claim on Menzi project; services incomplete or unsatisfactory.
- Counterclaim for actual and moral damages and attorney’s fees P10,000.
Submission to Commissioner and Commissioner’s Report
- Parties agreed trial would be heard before a Commissioner because pleadings showed factual agreement on services, leaving assessment of proper fees and balance as main dispute.
- Commissioner’s report in summary:
- IRRI project: appellee entitled to $28,000 (20% of $140,000 paid to appellant).
- Other projects: appellee entitled to P51,539.91.
- Less sum of P69,475.46 already paid by appellant (note trial court quoted P69,475.46; parties’ pleadings mention similar payments).
- Recommended attorney’s fees of P5,000 as “just and reasonable” under Art. 2208(11), considering number of hearings, technical nature, voluminous exhibits and manner of counsel’s handling.
- At hearing on Commissioner’s Report, counsels stated no objection to findings of fact and agreed only two legal issues remained: (1) applicability of estoppel under facts stated; (2) whether payment in dollars was legally permissible and, if not, rate of exchange to convert to pesos.
Assignments of Error by Appellant
- I. Trial court erred by not declaring Exhibit 1 and Exhibit 1-A to have estoppel effect or to constitute binding admissions limiting appellee’s claims.
- II. Trial court erred in holding balance on IRRI project should be paid based on exchange rate at time of payment of judgment rather than at time obligation arose; appellant contended official rate August 25, 1961 was P2.00 = $1.00 and that legal presumption should favor conversion at that official rate.
- III. Trial court erred in not holding aggregate balance due was only P15,792.05.
- IV. Trial court erred in awarding P8,000 attorney’s fees despite Commissioner’s finding of P5,000 which appellee did not question.
- V. Trial court erred in not granting relief on appellant’s counterclaim.
Supreme Court Issue Framing (as agreed by parties)
- Whether, under the Commissioner's findings, doctrine of estoppel applies to preclude appellee from asserting amounts beyond those in Exhibit 1-A.
- Whether payment of the appellee’s dollar-denominated fee for the IRRI project may be enforced in dollars, and if not, what exchange rate should be applied for conversion to Philippine pesos.
Court’s Analysis — Estoppel and Effect of Exhibit 1-A
- Appellant’s contentions:
- Exhibit 1-A itemized services and amounts and thus barred appellee from later asserting inconsistent claims.
- Estoppel does not require actual reliance by appellant; it suffices that representations were intended to make defendant act.
- Exhibit 1-A was a formal admission and prima facie accurate, not impeachable except for fraud or mistake.
- Exhibit 1-A represented appellee’s interpretation of contract and thus conclusive.
- Appellee’s contentions:
- Exhibit 1-A was prepared under innocent mistake; appellee had not yet consulted counsel when it was prepared.
- Appellant was aware of actual services and did not rely on Exhibit 1-A; appellant consistently denied the accounts.
- Exhibit 1-A can be corrected when based on mistake; appellee not estopped.
- Commissioner’s findings adopted by trial court:
- Plaintiff vacillated but defendant did not rely or believe plaintiff’s different claims; defendant insisted plaintiff was only entitled to P10,861.08 per exhibit 6 (r
