F.A.T. Kee Computer Systems, Inc. vs. Online Networks International, Inc.

Estoppel by silence and acceptance of payments bars a creditor from later denying the exchange rate offered by the debtor; thus, the ₱37:US$1 rate governed FAT KEE’s foreign-currency obligation. The Court also ruled that non-attachment of the transcript of stenographic notes does not render a Rule 45 petition fatally defective where the records are subsequently elevated, and that conflicting factual findings of the RTC and the Court of Appeals fall within a recognized exception to the rule that only questions of law may be raised in a petition for review on certiorari.

FAT KEE Computer Systems, Inc. and Online Networks International, Inc. are domestic corporations; FAT KEE sold computer equipment and provided maintenance services, while ONLINE sold computer units, parts, and software. FAT KEE was a client of ONLINE, and their dealings included purchases of imported computer products billed in US dollars. The governing statutory backdrop includes Republic Act No. 8183, which repealed Republic Act No. 529 and removed the prohibition on stipulating a currency other than Philippine currency, while leaving the conversion rate for foreign-currency obligations to jurisprudence.

FAT KEE Computer Systems, Inc., a domestic corporation engaged in selling computer equipment and conducting maintenance services for the units it sold, purchased computer printers from Online Networks International, Inc., also a domestic corporation principally engaged in selling computer units, parts, and software. The purchases were covered by Invoice Nos. 4680, 4838, 5090, and 5096 for a total purchase price of US$136,149.43. The invoice receipts stipulated that interest at 28% per annum would be charged on all overdue accounts and that an additional sum equal to 25% of the amount would be charged for attorney’s fees plus cost of collection in case of suit. FAT KEE had issued purchase orders, including one dated October 23, 1997 and another dated November 26, 1997, both denominated in US dollars.

According to ONLINE, sometime in November 1997 it sold the printers to FAT KEE, and FAT KEE, through its President Frederick Huang, Jr., later offered to pay its US dollar obligations in Philippine pesos at the exchange rate of ₱40:US$1. ONLINE accepted the offer, and the amount payable was computed at ₱5,445,977.20. Between March and May 1998, FAT KEE made payments totaling ₱2,502,033.06. As of May 12, 1998, the balance was ₱2,943,944.14. Because the obligations matured in December 1997, ONLINE applied the 28% interest on the unpaid amount, but, in view of the parties’ good business relationship, applied it for three months only, making the total amount due plus interest ₱3,012,636.17. FAT KEE made additional payments of ₱2,256,541.12, leaving a balance of ₱756,095.05. Despite repeated demands and a final demand letter, FAT KEE did not pay, prompting ONLINE to file the complaint.

FAT KEE denied any agreement to pay in US dollars and claimed that the invoice receipts quoting the purchase price in US dollars were unilaterally prepared by ONLINE. It admitted offering to pay in Philippine pesos but asserted that the amount owing was only ₱5,067,925.34, as reflected in the Statement of Account dated December 9, 1997 sent by ONLINE. FAT KEE said it tendered payments in Philippine pesos in accordance with that SOA and ONLINE accepted them. It denied agreeing to the ₱40:US$1 conversion rate and claimed it had fully paid its obligations. By way of counterclaim, it sought ₱250,000.00 as attorney’s fees.

At trial, ONLINE presented Peter Jeoffrey Goco, James Payoyo, and Sonia Magpili. Goco, ONLINE’s Legal Officer, testified that he monitored outstanding accounts and sent demand letters; FAT KEE had an outstanding balance of a little over ₱756,000.00. He said the invoice receipts were denominated in US dollars because ONLINE sold imported computer products and, given currency fluctuations, adopted a business policy of billing clients in US dollars. FAT KEE’s outstanding balance was roughly US$136,000.00. When ONLINE demanded payment, FAT KEE negotiated to pay in Philippine pesos, and the parties subsequently agreed to a ₱40:US$1 conversion rate. FAT KEE made partial payments, but as of May 1998 ₱756,095.05 remained unpaid. FAT KEE later sent a letter insisting there was no agreement on the exchange rate and that it could not pay because of extraordinary currency fluctuations. ONLINE’s lawyers sent a demand letter, which went unheeded. Payoyo, an Account Manager, testified that in November 1997 FAT KEE submitted a Purchase Order for Hewlett Packard computers and printers quoted in US dollars, and that a prior Purchase Order dated October 23, 1997 was also denominated in US dollars. On January 15, 1998, ONLINE officials met with Huang and his lawyer to discuss the payment scheme. ONLINE proposed dividing the unpaid amount of more than US$136,000.00 in two, with 50% paid in US dollars and 50% in Philippine pesos at ₱41:US$1. FAT KEE offered ₱35:US$1, which ONLINE rejected, and the parties subsequently agreed to ₱40:US$1. Magpili, ONLINE’s Executive Vice President, testified that she attended the January 15, 1998 meeting, where the split payment was discussed. Huang later called ONLINE to request a lower rate of ₱40:US$1, to which ONLINE agreed. FAT KEE made partial payments from March 1998 but later tried to negotiate a lower rate; ONLINE no longer agreed because the account had fallen due in December 1997. On cross-examination, Magpili admitted that FAT KEE did not execute any written confirmation of its agreement to the split payment and the ₱40:US$1 rate.

For FAT KEE, Frederick Huang, Jr. testified that the exchange rate used to compute its unpaid obligation was ₱34:US$1. He derived this from the December 9, 1997 SOA, in which the unpaid dollar amounts in Invoice Nos. 4680 and 4838 were denominated in Philippine pesos as ₱2,343,414.33 and ₱1,502,033.06, respectively; dividing those amounts by the dollar amounts yielded ₱34:US$1. FAT KEE applied the same rate to Invoice Nos. 5090 and 5096, converting their dollar amounts to ₱384,107.52 and ₱466,480.00. Huang stated that FAT KEE quoted the November 26, 1997 Purchase Order in US dollars upon Payoyo’s instructions, and that ONLINE’s Accounting Department informed him the equipment would not be delivered unless the Purchase Order was in US dollars. He maintained there was no agreement for payment in US dollars and no specific exchange rate. The January 15, 1998 meeting failed to produce an agreement. The next day, Payoyo wrote to FAT KEE confirming a supposed ₱41:US$1 rate; on February 23, 1998, Payoyo wrote that the new rate was ₱40:US$1; and on March 2, 1998, Huang communicated that FAT KEE’s Board of Directors agreed to settle the outstanding balance at ₱37:US$1. FAT KEE continued paying in Philippine pesos until it believed the obligation was fully paid, but later received demand letters for ₱756,095.05. Mayumi Huang, FAT KEE’s Operations Manager, admitted issuing the November 26, 1997 Purchase Order for $13,720.00. In rebuttal, Melissa Tan, ONLINE’s Credit and Collection Supervisor, testified that the December 9, 1997 SOA was unauthorized and that FAT KEE was informed of this. Magpili had shown her a copy in December 1997 and asked if she approved it; Tan did not issue it and was unaware of its issuance. The absence of her signature meant it was not authorized, since the standard procedure required her to review and approve such documents. The SOA had been prepared by Edwin Morales, an Accountant, who said he merely wanted to give FAT KEE an initial computation but mistakenly included billings denominated in US dollars. At the January 15, 1998 meeting, FAT KEE was informed that the SOA was not official, and the parties negotiated the conversion rate. On cross-examination, Tan revealed that ONLINE did not rectify or correct the SOA and took no disciplinary action against Morales. In surrebuttal, Huang maintained that the parties failed to agree on the payment and the ₱37:US$1 proposal.

The RTC found no agreement on the exchange rate and relied on the December 9, 1997 SOA and Huang’s testimony to set the rate at ₱34:US$1; it also found that FAT KEE had paid an excess of ₱62,539.24. The Court of Appeals found that the RTC misappreciated the evidence, that any misconception from the SOA should have been rectified at the January 15, 1998 meeting before FAT KEE made any payment, and that FAT KEE began paying the dollar-denominated invoices only on March 17, 1998.

• Procedural Completeness: Petitioner maintained that the petition is complete in form and substance; there was no need to attach the transcript of stenographic notes because respondent did not dispute the accuracy of the quoted portions and the petition did not request a reevaluation of evidence; if attachment was required, the rules should be relaxed to serve substantive justice.
• Questions of Law: Petitioner argued that the petition did not raise only factual issues; the Court of Appeals erred in re-evaluating the evidence and substituting its own interpretation of the testimonies of the witnesses.
• No Foreign Currency Agreement: Petitioner argued that it did not agree to enter into a foreign currency-based transaction; the US dollar invoice receipts were unilaterally prepared by ONLINE, and the Accounting Department of ONLINE required the Purchase Order to be denominated in US dollars, with Frederick Huang, Jr. merely complying upon the instructions of Payoyo.
• No ₱37:US$1 Agreement: Petitioner maintained that there was no agreement to use a ₱37:US$1 exchange rate.
• Estoppel from December SOA: Petitioner argued that ONLINE was estopped by the December 9, 1997 Statement of Account, which denominated its unpaid obligation in Philippine pesos; FAT KEE allegedly used the SOA as its only basis for payment and ONLINE accepted payments made in accordance with it.

• Procedural Defect: Respondent argued that the petition was fatally defective for failure to attach the transcript of stenographic notes of the RTC proceedings.
• Questions of Fact: Respondent contended that the petition raised only factual issues, which are not proper in a petition for review on certiorari.
• Estoppel Not Applicable: Respondent argued that estoppel could not be invoked against it because FAT KEE did not act or rely on the representations in the December 9, 1997 Statement of Account; FAT KEE was informed that the SOA was erroneous and unauthorized, and the parties subsequently met and negotiated the exchange rate.
• Attorney’s Fees: Respondent challenged the award of attorney’s fees in favor of FAT KEE.

• Non-Attachment of TSN: Whether the failure to attach the transcript of stenographic notes to the petition for review on certiorari renders the petition fatally defective.
• Questions of Fact: Whether the petition improperly raises questions of fact and should be dismissed under Rule 45.
• Foreign Currency Transaction: Whether FAT KEE agreed to enter into a foreign currency-based transaction.
• Exchange Rate Agreement: Whether the parties agreed to use the ₱37:US$1 exchange rate.
• Estoppel from December SOA: Whether ONLINE was estopped by the December 9, 1997 Statement of Account from claiming a different exchange rate.
• Computation of Balance: Whether the Court of Appeals correctly computed the remaining unpaid balance.

• Non-Attachment of TSN: No. The non-attachment did not render the petition fatally defective; the TSN formed part of the records and was cured by the subsequent elevation of the case records, and procedural rules are liberally construed.
• Questions of Fact: No. Although the petition raised factual questions, the conflicting findings of the RTC and the Court of Appeals fell under a recognized exception to Rule 45’s questions-of-law requirement.
• Foreign Currency Transaction: The contention did not warrant reversal. The petition was denied, and the Court upheld the Court of Appeals’ disposition on the foreign-currency-based transaction.
• Exchange Rate Agreement: Yes, in effect. No express written agreement was required; ONLINE’s silence and acceptance of payments after FAT KEE’s ₱37:US$1 offer estopped it from denying that rate.
• Estoppel from December SOA: No. FAT KEE could not invoke estoppel based on the December 9, 1997 SOA because the parties’ January 15, 1998 meeting and subsequent negotiations showed they did not intend to be bound by it, and FAT KEE began paying only in March 1998.
• Computation of Balance: Modified. Applying ₱37:US$1 to US$136,149.43 yields ₱5,037,528.91; deducting ₱4,758,574.18 leaves ₱278,954.73.

• Non-Attachment of TSN: Rule 45, Section 4 of the Rules of Court requires that the petition be accompanied by such material portions of the record as would support the petition, but this requirement is not an ironclad rule. Under Rule 45, Section 7, the Supreme Court may require or allow the filing of such pleadings, briefs, memoranda, or documents as it may deem necessary, and under Rule 45, Section 8, if the petition is given due course, the Court may require elevation of the complete record or specified parts. Because the TSN formed part of the records of the case, FAT KEE’s failure to attach the relevant portions was cured by the subsequent elevation of the case records. This is consistent with the doctrine that procedural rules should be liberally construed to promote just, speedy, and inexpensive determination of every action or proceeding.
• Questions of Fact: A question of law arises when there is doubt as to what the law is on a certain state of facts, while a question of fact arises when the doubt concerns the truth or falsity of the alleged facts. For a question to be one of law, it must not involve an examination of the probative value of the evidence. Rule 45, Section 1 provides that a petition for review on certiorari shall raise only questions of law. This rule is subject to exceptions, one of which is when the findings of fact of the Court of Appeals and the RTC are conflicting. That exception applied because the RTC and the Court of Appeals reached conflicting factual findings on the exchange rate and estoppel.
• Foreign Currency Transaction: After a meticulous review of the records, the Court denied the petition. The Court did not disturb the Court of Appeals’ finding that FAT KEE had acquiesced to the foreign-currency-based transaction, noting FAT KEE’s previous dealings with ONLINE, the US-dollar-denominated transactions in November 1997, FAT KEE’s willingness to negotiate the conversion rate, and its payments under the dollar-denominated invoices. The Court’s own analysis focused on the parties’ estoppel and the applicable conversion rate.
• Exchange Rate Agreement: The Court upheld the Court of Appeals’ ruling that estoppel applied as regards ONLINE’s implied acquiescence to the ₱37:US$1 rate. On March 2, 1998, after a series of proposals on the conversion rate, FAT KEE finally offered to settle its outstanding balance at ₱37:US$1. ONLINE did not respond. Thereafter, on March 17, 1998, FAT KEE began remitting payments continuously, which ONLINE duly accepted. Following British American Tobacco vs. Camacho, ONLINE communicated, through its silence and acceptance of payments, that it was agreeable to the ₱37:US$1 rate. ONLINE should not be allowed to adopt a contrary position to the detriment of FAT KEE.
• Estoppel from December SOA: FAT KEE could not invoke estoppel against ONLINE for the latter’s issuance of the December 9, 1997 SOA. Any misconception on FAT KEE’s part engendered by the SOA should have already been rectified when the parties met on January 15, 1998. The testimonial evidence of both parties established that during the meeting they tried but failed to reach an agreement on the payment and the exchange rate. Whether FAT KEE was informed that the SOA was unauthorized was no longer of much importance. By submitting their respective proposals and counter-proposals on the mode of payment and the exchange rate, FAT KEE and ONLINE demonstrated that it was not their intention to be further bound by the SOA, especially as to the exchange rate. Moreover, FAT KEE only started making payments on the subject invoice receipts on March 17, 1998, or two months after the meeting. Under Mijares vs. Court of Appeals, one who claims the benefit of estoppel must not have been misled through his own want of reasonable care and circumspection; lack of diligence is generally fatal, and estoppel is denied where the party claiming it was put on inquiry as to the truth and had available means for ascertaining it. After participating in the January 15, 1998 meeting, submitting its own proposals, and further renegotiating for a lower exchange rate, FAT KEE could not insist that it was completely under the impression that the applicable rate was ₱34:US$1 as purportedly indicated in the December 9, 1997 SOA.
• Computation of Balance: The Court of Appeals inadvertently erred in computing the remaining balance. According to Invoice Nos. 4680, 4838, 5090, and 5096, the total unpaid amount is US$136,149.43. Applying the ₱37:US$1 rate yields ₱5,037,528.91, not ₱5,148,528.91 as determined by the Court of Appeals. Since FAT KEE had already paid a total amount of ₱4,758,574.18, the total unpaid amount owed to ONLINE is ₱278,954.73.

• Estoppel — Estoppel is an equitable principle rooted in natural justice that prevents persons from going back on their own acts and representations to the prejudice of others who have relied on them. It is codified in Article 1431 of the Civil Code and Rule 131, Section 2(a) of the Rules of Court. The elements are: first, the actor who usually must have knowledge, notice, or suspicion of the true facts communicates something to another in a misleading way, either by words, conduct, or silence; second, the other in fact relies, and relies reasonably or justifiably, upon that communication; third, the other would be harmed materially if the actor is later permitted to assert any claim inconsistent with his earlier conduct; and fourth, the actor knows, expects, or foresees that the other would act upon the information given, or that a reasonable person in the actor’s position would expect or foresee such action. In this case, FAT KEE could not invoke estoppel based on the December 9, 1997 SOA because it was not reasonably misled, while ONLINE was estopped by its silence and acceptance of payments from denying the ₱37:US$1 rate.
• Estoppel by Silence and Acceptance of Payments — A party may communicate assent through silence and acceptance of payments, and it cannot later adopt an inconsistent position to the detriment of the other party. ONLINE’s failure to respond to FAT KEE’s March 2, 1998 offer of ₱37:US$1, followed by its acceptance of continuous payments beginning March 17, 1998, constituted implied acquiescence to that rate.
• No Estoppel Where Party Was Negligent — One who claims the benefit of estoppel on the ground of being misled by another’s representations must not have been misled through his own want of reasonable care and circumspection. Lack of diligence is generally fatal; if a party conducts himself with careless indifference to means of information reasonably at hand or ignores highly suspicious circumstances, he may not invoke estoppel. FAT KEE could not rely on the December 9, 1997 SOA because it participated in subsequent negotiations and renegotiated the exchange rate.
• Liberal Construction of Procedural Rules — Procedural rules should be liberally construed in order to promote their objective and assist the parties in obtaining just, speedy, and inexpensive determination of every action or proceeding. This doctrine justified excusing FAT KEE’s non-attachment of the TSN where the records were subsequently elevated.
• Rule 45 — Questions of Law and Conflicting Factual Findings — A petition for review on certiorari under Rule 45 shall raise only questions of law. However, the rule admits exceptions, one of which is when the findings of fact of the Court of Appeals and the RTC are conflicting. Because the RTC and the Court of Appeals reached conflicting factual conclusions on the exchange rate and estoppel, the Supreme Court reviewed the factual issues.
• Foreign Currency Obligations Under R.A. No. 8183 — Under Republic Act No. 8183, which repealed Republic Act No. 529, parties to a contract may agree that the obligation or transaction shall be settled in any currency other than Philippine currency at the time of payment. The law does not provide the applicable rate of exchange for converting foreign-currency-incurred obligations into their peso equivalent; jurisprudence under R.A. No. 529 remains applicable, such that obligations in foreign currency may be discharged in Philippine currency based on the prevailing rate at the time of payment. In this case, however, the parties’ dealings and estoppel fixed the applicable rate at ₱37:US$1.

• "The elements of estoppel are: first, the actor who usually must have knowledge, notice or suspicion of the true facts, communicates something to another in a misleading way, either by words, conduct or silence; second, the other in fact relies, and relies reasonably or justifiably, upon that communication; third, the other would be harmed materially if the actor is later permitted to assert any claim inconsistent with his earlier conduct; and fourth, the actor knows, expects or foresees that the other would act upon the information given or that a reasonable person in the actor's position would expect or foresee such action." — This passage states the canonical elements of estoppel applied by the Court in resolving both FAT KEE’s claim of estoppel and ONLINE’s implied acquiescence.
• "In the instant case, we find that FAT KEE cannot invoke estoppel against ONLINE for the latter’s issuance of the SOA on December 9, 1997. The Court agrees with the Court of Appeals’ ruling that any misconception on the part of FAT KEE engendered by the issuance of the SOA should have already been rectified when the parties subsequently met on January 15, 1998." — This is the ratio decidendi rejecting FAT KEE’s estoppel argument based on the December 9, 1997 Statement of Account.
• "Following the dictum stated in British American Tobacco, ONLINE communicated, through its silence and acceptance of payments, that it was agreeable to the ₱37:US$1 rate. Indeed, ONLINE should not be allowed to adopt a contrary position to the detriment of FAT KEE." — This passage establishes the controlling estoppel by silence and acceptance of payments, fixing the applicable exchange rate at ₱37:US$1.
• "According to Invoice Nos. 4680, 4838, 5090 and 5096, the total unpaid amount is US$136,149.43. By applying ₱37:US$1 rate on the unpaid amount, the resulting balance is ₱5,037,528.91, not ₱5,148,528.91 as determined by the Court of Appeals. As FAT KEE has already paid a total amount of ₱4,758,574.18, the total unpaid amount owed to ONLINE is ₱278,954.73." — This passage corrects the Court of Appeals’ arithmetic and states the final unpaid balance.

• British American Tobacco vs. Camacho, G.R. No. 163583, August 20, 2008, 562 SCRA 511 — Cited for the doctrine and elements of estoppel; the Court applied it to hold that ONLINE’s silence and acceptance of payments estopped it from denying the ₱37:US$1 rate.
• Mijares vs. Court of Appeals, 338 Phil. 274 (1997) — Cited for the rule that a party claiming estoppel must not have been misled through its own want of reasonable care and circumspection; lack of diligence is generally fatal. The Court applied this against FAT KEE.
• Asia World Recruitment, Inc. vs. National Labor Relations Commission — Cited in the Court of Appeals’ discussion for the rule that obligations in foreign currency may be discharged in Philippine currency based on the prevailing rate at the time of payment.
• Tirazona vs. Court of Appeals, G.R. No. 169712, March 14, 2008, 548 SCRA 560, 581 — Cited for the distinction between a question of law and a question of fact.
• Insular Life Assurance Company, Ltd. vs. Court of Appeals, G.R. No. 126850, April 28, 2004, 428 SCRA 79, 85-86 — Cited for the exceptions to the rule that a petition for review on certiorari under Rule 45 shall raise only questions of law.
• Grand Boulevard Hotel vs. Genuine Labor Organization of Workers in Hotel, Restaurant and Allied Industries (GLOWHRAIN), 454 Phil. 463 (2003) — Cited for the liberal construction of procedural rules.

• Rule 45, Section 4, Rules of Court — Requires that the petition for review on certiorari be accompanied by such material portions of the record as would support the petition. The Court held that non-attachment of the TSN did not render the petition fatally defective because the records were subsequently elevated.
• Rule 45, Section 7, Rules of Court — Allows the Supreme Court to require or allow the filing of such pleadings, briefs, memoranda, or documents as it may deem necessary. This supported the Court’s relaxation of the attachment requirement.
• Rule 45, Section 8, Rules of Court — Provides that if the petition is given due course, the Supreme Court may require the elevation of the complete record of the case or specified parts thereof. The elevation of the records cured the non-attachment of the TSN.
• Rule 45, Section 1, Rules of Court — Provides that a petition for review on certiorari shall raise only questions of law, which must be distinctly set forth. The Court applied the exception for conflicting findings of fact of the Court of Appeals and the RTC.
• Rule 1, Section 6, Rules of Court — Provides for the liberal construction of the Rules of Court to promote a just, speedy, and inexpensive determination of every action or proceeding. The Court invoked this in excusing the procedural defect.
• Article 1431, Civil Code — Codifies estoppel: through estoppel, an admission or representation is rendered conclusive upon the person making it and cannot be denied or disproved as against the person relying thereon. The Court used this as the statutory basis for the estoppel analysis.
• Rule 131, Section 2(a), Rules of Court — Establishes a conclusive presumption that whenever a party has, by his own declaration, act, or omission, intentionally and deliberately led another to believe a particular thing true and to act upon such belief, he cannot, in any litigation arising out of such declaration, act, or omission, be permitted to falsify it. This reinforced the estoppel ruling.
• Republic Act No. 8183 — Repealed Republic Act No. 529 and removed the prohibition on stipulating a currency other than Philippine currency, allowing obligations or transactions to be settled in the currency agreed upon by the parties. It does not provide the applicable conversion rate, so jurisprudence under R.A. No. 529 remains applicable.
• Republic Act No. 529 — The prior law that prohibited stipulation of currency other than Philippine currency; it was repealed by Republic Act No. 8183, but jurisprudence interpreting it regarding the rate of conversion remains applicable.

Renato C. Corona (Chief Justice, Chairperson), Presbitero J. Velasco, Jr., Mariano C. del Castillo, and Jose Portugal Perez concurred. No separate concurring opinions are summarized in the text.
