Breach of Express Warranty: Seller Liable for Unpaid Taxes Despite Transfer of Ownership

The Supreme Court has ruled that a seller who assures a buyer that all taxes and duties on a vehicle have been paid can be held liable for those amounts even after ownership has transferred, if the assurance turns out to be false. The case of Harrison Motors Corporation v. Navarro (G.R. No. 132269, April 27, 2000) clarifies how express warranties operate in sales contracts and who bears the burden of unpaid taxes between an importer-assembler and a buyer.

The Facts of the Case

In June 1987, Harrison Motors Corporation sold two Isuzu Elf trucks to Rachel Navarro, who operated a cargo trucking business. Before the sale, Harrison Motors' president assured Navarro that all Bureau of Internal Revenue (BIR) taxes and customs duties on the imported parts used to assemble the trucks had been paid.

The trucks were registered with the Land Transportation Office (LTO). However, in December 1988, government agents seized the trucks after discovering that BIR taxes and customs duties remained unpaid. The BIR and Bureau of Customs (BOC) ordered Navarro to pay the assessments or lose her trucks.

When Navarro asked Harrison Motors for the receipts proving payment, the company refused. She then paid P32,943.00 to secure the release of her trucks and demanded reimbursement. When Harrison Motors refused, Navarro filed a complaint for a sum of money.

The Issue

The central question was whether Harrison Motors, as the seller and importer-assembler, remained liable for the unpaid taxes and customs duties even though ownership of the trucks had already transferred to Navarro at the time the government demanded payment.

The Ruling: Seller's Express Warranty Was Breached

The Supreme Court affirmed the lower courts' decisions ordering Harrison Motors to reimburse Navarro. The Court held that Harrison Motors' representation that all taxes and duties had been paid constituted an express warranty under Article 1546 of the Civil Code.

This provision covers any affirmation of fact or promise by the seller that induces the buyer to purchase the thing. The Court noted that Navarro likely would not have bought the trucks had she known the taxes were unpaid.

The warranty was breached when Harrison Motors refused to provide the receipts, leaving Navarro unable to prove payment to the government. Under Article 1599 of the Civil Code, a buyer who accepts or keeps goods after a breach of express warranty may maintain an action against the seller for damages.

Why the Seller Remained Liable for Taxes

The Court rejected Harrison Motors' argument that the administrative issuances—the Memoranda of Agreement between the BIR, BOC, and LTO—imposed new taxes that violated the non-impairment clause and the principle of non-retroactivity of laws.

The Court clarified that these issuances did not impose new taxes. They merely provided procedures for enforcing payment of taxes already due under existing law, specifically Sections 135-A and 163 of the National Insurance Revenue Code. The taxes were designated as assembler's/manufacturer's tax, which the importer-assembler was obligated to pay from the time of importation.

The Court also dismissed the argument that Harrison Motors could not have registered the trucks if taxes were unpaid. The government was aware that vehicles were being registered despite unpaid taxes, which is precisely why the Memoranda of Agreement were executed.

Practical Takeaways

• A seller's verbal assurance about a product's condition or status can create a legally binding express warranty. If the assurance proves false, the seller may be liable for damages even after ownership has passed.
• Buyers of vehicles assembled from imported parts should demand and keep copies of tax and duty payment receipts. These documents are essential evidence if the government later questions the vehicle's tax status.
• Tax obligations follow the party who incurred them, not the current owner of the property. An importer-assembler cannot escape liability for unpaid taxes simply by selling the finished product.
• Administrative regulations that merely implement existing tax laws do not violate the non-impairment clause. They are presumed prospective and do not create new obligations retroactively.
• A buyer who pays taxes that the seller was obligated to pay may seek reimbursement. Keeping the goods and suing for damages is a valid remedy under the Civil Code.
