Case Summary (G.R. No. 132269)
Transactional Setting and Administrative Framework
In June 1987, petitioner, through its president Renato Claros, sold the two (2) Isuzu Elf trucks to respondent. Before the sale, Claros represented to respondent that all BIR taxes and customs duties for the parts used on the trucks had already been paid. The administrative mechanisms later invoked by government were anchored on inter-agency arrangements between the Bureau of Internal Revenue (BIR), the Land Transportation Office (LTO), and the Bureau of Customs (BOC). On 10 September 1987, the BIR and the LTO executed a Memorandum of Agreement (MOA) requiring that, prior to LTO registration of any assembled or re-assembled motor vehicle using imported parts, a Certificate of Payment must first be obtained from the BIR to prove payment of the taxes required under existing laws. Thereafter, on 12 October 1987, the BOC issued Customs Memorandum Order No. 44-87, prescribing rules, regulations, and procedure for the voluntary payment of duties and taxes on imported motor vehicles locally assembled by non-assemblers. Pursuant to the BIR-LTO MOA, the BIR then issued Revenue Memorandum Order No. 44-87 on 18 December 1987, detailing the procedure for issuance of the Certificate of Payment for internal revenue taxes needed for LTO registration. Finally, on 16 June 1988, the BIR, BOC, and LTO executed a tripartite MOA requiring, before LTO registration of locally assembled motor vehicles using imported component parts, that certificates of payment from both the BIR and the BOC be presented to show that existing taxes and customs duties had been paid.
Seizure of the Trucks and Respondent’s Payment
In December 1988, government agents seized and detained the two (2) Elf trucks after discovering that the corresponding BIR taxes and customs duties for their imported component parts remained unpaid. The BIR and the BOC ordered respondent to pay the proper assessments; otherwise, her trucks would be impounded. Respondent sought from Claros the receipts evidencing the alleged prior payments of taxes and duties, but Claros refused. Respondent then demanded that Claros pay the assessed taxes and warned that she would require reimbursement should she be compelled to pay the assessments herself. Those demands were ignored. To secure the trucks’ immediate release and comply with her business commitments, respondent paid the assessed BIR taxes and customs duties totaling P32,943.00.
Refusal of Reimbursement and Filing of the Complaint
After paying, respondent returned to petitioner’s office to request reimbursement, but petitioner again refused. She then sent a demand letter through counsel. When petitioner still ignored the demand, respondent filed on 24 September 1990 a complaint for a sum of money with the Regional Trial Court of Makati.
Petitioner later defaulted in the litigation. Respondent filed on 24 May 1991 a Motion to Declare Defendant in Default, which the RTC granted on the same day. On 18 November 1991, respondent moved for the reception of her evidence ex parte because petitioner had not yet filed a motion to lift the order of default. On 22 November 1991, the RTC ordered the reception of respondent’s evidence ex parte. Petitioner filed its motion to lift the order of default only on 2 December 1991, but the RTC denied it on 20 January 1992 for failure to attach an affidavit of merit showing a valid and meritorious defense.
RTC Judgment and CA Affirmance
On 5 March 1992, the RTC rendered judgment ordering petitioner to reimburse respondent P32,943.00 for the customs duties and internal revenue taxes respondent had paid to discharge the trucks from government custody. It also awarded P7,500.00 as attorneys fees and taxed the costs against petitioner. The Court of Appeals later affirmed the RTC decision, prompting the present review on certiorari by petitioner.
Issues Framed by Petitioner’s Arguments
Petitioner contended that it no longer had any obligation to pay the additional taxes and customs duties imposed by the administrative issuances because those measures allegedly took effect after the parties’ contract of sale. Petitioner asserted that treating the administrative regulations as requiring tax payments from it would violate the non-impairment clause of the Constitution and the non-retroactivity principle under Art. 4 of the Civil Code. Petitioner also claimed that it had already paid the assessed taxes and duties; otherwise, it argued, it would not have been able to secure customs release of the spare parts and register the finished trucks with the LTO.
Administrative Regulations Were Procedural and Did Not Create New Taxes
The Court rejected petitioner’s premise that the administrative issuances imposed new tax liabilities. The decision held that Customs Memorandum Order No. 44-87 was concerned with the rules, regulations, and procedure for the payment of duties and taxes on imported vehicles locally assembled by non-assemblers. It did not charge any new tax. It provided the procedure for voluntary payment of any unpaid customs duties on locally assembled vehicles using imported component parts. Likewise, Revenue Memorandum Order No. 44-87 did not exact any tax; it outlined the procedure for processing and issuing the BIR Certificate of Payment for purposes of LTO registration. It was issued pursuant to the MOA between the LTO and the BIR implementing secs. 135-A and 163 of the 1987 National Internal Revenue Code (NIRC).
The Court further found meritless petitioner’s claim that the BIR-LTO MOA of 10 September 1987 and the tripartite MOA of 16 June 1988 were administrative regulations prescribing additional taxes. It examined the purpose of those agreements and concluded that they were designed to curb schemes whereby importers evaded correct taxes and customs duties by importing parts, assembling them locally, and then selling the finished vehicles to local buyers. The MOAs required that before LTO registration, a BIR certificate (and, under the tripartite arrangement, also a BOC certificate) be presented to prove that taxes and customs duties required under existing laws had been paid. Accordingly, petitioner's contention that liability for tax payments under those administrative processes impaired contract rights failed because what the Constitution prohibits is passage of a law that enlarges, abridges, or otherwise changes the intention of contracting parties, and the questioned issuances did not alter the substantive tax obligations under existing law.
Who Was Duty-Bound to Pay: Petitioner as Importer-Assembler/Manufacturer
The Court then addressed the more direct allocation of responsibility. It ruled that the administrative regulations requiring certificates of payment did not themselves determine who bore the tax burden. Petitioner maintained that respondent, as buyer, should have paid the BIR taxes and customs duties after purchase. Petitioner emphasized that by the time the memorandum orders and MOAs took effect, the trucks were already sold to respondent and that, therefore, petitioner did not own them and had no further concern with later payments.
The Court held that the administrative agreements showed an intent to enforce payment of taxes on assemblers/manufacturers who imported component parts without paying the correct assessments. It relied on the WHEREAS clauses of both the 10 September 1987 MOA and the 16 June 1988 tripartite MOA, which referred to the evasion of higher taxes on imported motor vehicles by persons assembling or re-assembling vehicles using imported parts. It noted that Par. 9 of the 16 June 1988 MOA specified that the BIR would collect the assemblers/manufacturers tax, while the BOC would collect duties and taxes and ad valorem tax. Thus, even though respondent was required to obtain the certificates for LTO registration, petitioner remained the party duty-bound to pay the revenue taxes and customs duties because the obligation arose not from the administrative regulations themselves, but from the tax laws existing at the time of importation. The Court stressed that between petitioner, as importer and assembler/manufacturer, and respondent, as buyer, petitioner was the one with the tax payment obligation.
The Court also rejected petitioner’s argument grounded on non-retroactivity. It recognized that administrative rulings and regulations are generally prospective, but held that the MOAs’ structure and purpose targeted the enforcement of taxes owed under the existing legal regime, particularly those owed by assemblers/manufacturers importing component parts without paying correct assessments. The Court therefore concluded that respondent’s ownership of the trucks at the time the MOAs took effect did not extinguish petitioner’s duty to pay the taxes due on the imported component parts.
Breach of Express Warranty and the Right to Reimbursement
The Court added that the controversy could not be resolved solely by classifying the administrative rules as procedural. It found that petitioner made representations that induced respondent to purchase the trucks. The Court characterized Claros’s pre-sale representation—namely that all BIR taxes and customs duties for the parts used on the trucks had been paid—as an express warranty under Art. 1546 of the Civil Code, which covers any affirmation of fact or promise by the seller that induces the buyer to purchase and the buyer indeed purchases in reliance on such affirmation or promise. It held that this warranty included warranties derived from express language, whether cast as a promise or as a representation.
The Court ruled that the express warranty was breached when petitioner refused to provide receipts evidencing payment. It treated the receipts as the best evidence respondent could present to the government to prove that BIR taxes and customs duties on the imported component parts were fully paid. Without such evidence, respondent was unable to prevent the trucks from being im

Case Syllabus (G.R. No. 132269)
- The case reached the Court as a review on certiorari assailing a Decision of the Court of Appeals that affirmed a Regional Trial Court of Makati ruling ordering Harrison Motors Corporation to reimburse Rachel A. Navarro the amount of P32,943.00 for taxes paid, plus P7,500.00 as attorneys fees, and costs of suit.
- The controversy stemmed from the seizure and detention of two Isuzu Elf trucks sold by Harrison Motors to Navarro, after government agents found alleged unpaid Bureau of Internal Revenue (BIR) taxes and customs duties on imported component parts used in assembling the trucks.
- The Court ultimately affirmed the Court of Appeals’ ruling and required Harrison Motors to reimburse Navarro and pay legal interest on P32,943.00 from 24 September 1990 until full payment.
Parties and Procedural Posture
- Harrison Motors Corporation was the petitioner seeking reversal of the Court of Appeals’ decision that upheld the trial court’s order for reimbursement.
- Rachel A. Navarro, the owner of RN Freight Lines, was the private respondent who filed the complaint for a sum of money and proceeded to recover the amounts she paid to secure release of the trucks.
- The Regional Trial Court of Makati granted Navarro’s Motion to Declare Defendant in Default on 24 May 1991 and received her evidence ex parte after Harrison Motors failed to timely secure lifting of the default.
- The RTC rendered judgment on 5 March 1992, ordering reimbursement for the taxes and duties paid and awarding attorneys fees and costs.
- The Court of Appeals sustained the RTC decision, prompting Harrison Motors to file this recourse of petitioner by review on certiorari.
Key Factual Allegations
- Harrison Motors, through its president Renato Claros, sold two Isuzu Elf trucks in June 1987 to Navarro, who operated a franchise-holder cargo fleet over Luzon through RN Freight Lines.
- Harrison Motors assembled the trucks using imported component parts, and the record showed it was a known importer, assembler, and manufacturer.
- Prior to the sale, Claros represented to Navarro that all BIR taxes and customs duties for the parts used on the trucks had been paid.
- On 10 September 1987, the BIR and the Land Transportation Office (LTO) entered into a Memorandum of Agreement (MOA) requiring that, before LTO registration of assembled/re-assembled motor vehicles using imported parts, a Certificate of Payment must first be obtained from the BIR to prove payment of required taxes under existing laws.
- On 12 October 1987, the Bureau of Customs (BOC) issued Customs Memorandum Order No. 44-87, providing rules and procedure for voluntary payment of duties and taxes on imported motor vehicles locally assembled by non-assemblers.
- Pursuant to the BIR–LTO MOA, the BIR issued on 18 December 1987 Revenue Memorandum Order No. 44-87, which set the procedure for processing and issuing the Certificate of Payment for internal revenue taxes for motor vehicle registration.
- On 16 June 1988, a tripartite MOA among the BIR, BOC, and LTO required a Certificate of Payment from the BIR and the BOC before LTO registration of locally assembled motor vehicles using imported component parts.
- In December 1988, government agents seized and detained the two trucks after discovering alleged unpaid BIR taxes and customs duties.
- The BIR and the BOC ordered Navarro to pay the assessments or face impounding of the trucks.
- Navarro sought receipts from Claros showing payment, but Claros refused to comply.
- Navarro demanded that Harrison Motors pay the assessed taxes and warned that she would seek reimbursement if she was forced to pay, but Harrison Motors ignored the demands.
- To secure the trucks’ immediate release and meet business commitments, Navarro paid P32,943.00, then demanded reimbursement, but Harrison Motors refused, leading her to send a demand letter and ultimately file suit.
- Navarro filed her complaint for a sum of money on 24 September 1990, and the RTC eventually declared Harrison Motors in default, scheduled ex parte reception of Navarro’s evidence, and later rendered judgment in her favor.
Statutory and Regulatory Context
- The Court recognized that the administrative framework involved MOAs and Memorandum Orders adopted by government agencies governing the issuance of certificates needed for LTO registration.
- The Court explained that Customs Memorandum Order No. 44-87 and Revenue Memorandum Order No. 44-87 did not create new tax liabilities but prescribed procedures for payment and documentation relating to taxes and duties already required under existing laws.
- The RTC and Court of Appeals’ sustaining view rested on the understanding that the administrative instruments served to enforce payment of taxes and duties applicable to the imported component parts.
- The Court anchored the substantive private-right basis of Navarro’s recovery on civil law principles governing express warranties in sales, including Art. 1546 of the Civil Code and the consequences of breach of express warranty under Art. 1599 of the Civil Code.
- The Court additionally cited the constitutional principle that Sec. 10, Art. III prohibits passage of a law that enlarges, abridges, or changes the intent of the contracting parties.
- For the retroactivity argument, the Court addressed the contention under Art. 4 of the Civil Code and treated the issue as intertwined with whether the administrative instruments imposed additional taxes.
Issues Raised by Petitioner
- Harrison Motors argued that it should not be obliged to pay alleged additional taxes and customs duties specified in the Memorandum Orders and the Memoranda of Agreement, claiming these admini
