Freight Charges and Estoppel: Understanding Contractual Obligations in Philippine Law

The Supreme Court's recent decision in Campos v. Commission on Audit (G.R. Nos. 253454 and 253551, December 3, 2025) provides important guidance on the legal consequences when government contracts expire but parties continue their business relationship. The case involves the Land Transportation Office (LTO) and Amalgamated Motors Philippines, Inc. (AMPI), which had a long-running Build-Operate-Transfer (BOT) agreement for the production of driver's licenses.

The ruling clarifies several key points: when contractual obligations end, how the principle of quantum meruit applies to payments for services already rendered, and who bears liability when government funds are disbursed without a valid contract.

The Facts of the Case

In 1984, AMPI entered into a BOT contract with the government to supply driver's licenses and identification cards. Under this arrangement, AMPI would install equipment and facilities, operate the system for a fixed period, and then transfer all assets to the government at the end of the contract term.

The contract was extended several times through supplemental agreements. The last one, dated September 22, 2000, authorized AMPI to supply an additional six million driver's licenses. By May 2006, AMPI had completed all deliveries under this agreement.

Despite the contract's expiration, AMPI continued supplying driver's licenses to LTO. From June 2006 to September 2006, AMPI billed LTO for over PHP 124 million worth of licenses. LTO could not process these payments without a new contract, leading to an impasse.

In November 2006, the Department of Transportation and Communications (DOTC) issued a memorandum directing LTO to favorably act on AMPI's claim and to commence procurement under Republic Act No. 9184 (Government Procurement Reform Act). Relying on this memorandum, LTO eventually paid AMPI a total of PHP 740,008,450.21 for deliveries made in 2012 and the first half of 2013—even though no new contract existed and no public bidding had occurred.

The COA Disallowance

The Commission on Audit (COA) issued Notices of Disallowance against these payments, finding that: (1) no public bidding was conducted in violation of Republic Act No. 9184; (2) there was no valid and enforceable contract between LTO and AMPI; and (3) the disbursements were irregular.

COA initially disallowed the full PHP 740 million but later reduced this amount to PHP 302,161,498.58, recognizing that AMPI was entitled to compensation under the equitable principle of quantum meruit—meaning payment for the reasonable value of services actually rendered, even without a valid contract.

COA also ordered the case referred to the Office of the Ombudsman for possible charges against the government officials who processed the payments.

The Supreme Court's Ruling

The Supreme Court upheld COA's disallowance but modified the liability of the government officials involved.

On the BOT obligations: The Court ruled that AMPI's continued operation beyond the contract term was irregular. Under the BOT framework defined in Republic Act No. 7718, the project proponent must transfer the facility to the government at the end of the fixed term. This obligation arises automatically upon contract expiration—it does not depend on the government making a formal demand.

The Court rejected AMPI's argument that subsequent supplemental agreements had waived the turnover requirement. None of these agreements contained an express waiver of the core BOT conditions, and the 2000 Supplemental Agreement expressly reaffirmed the BOT scheme.

On the absence of a valid contract: The Court found that the disallowance was proper because the payments were made without a valid and enforceable contract and without the required public bidding under Republic Act No. 9184.

On the liability of government officials: The Court partly granted the petition of the government officials (Campos et al.), ruling that they should be excused from solidary liability because they merely processed the payments in the ordinary course of their functions, without evident bad faith or gross negligence.

On AMPI's claim for full payment: The Court dismissed AMPI's petition, holding that AMPI, as the payee, is liable to return the amounts it received, less the actual costs it incurred in producing the licenses.

Practical Takeaways

• Contract expiration does not mean obligations disappear. In BOT arrangements, the duty to transfer facilities to the government arises automatically upon expiration of the contract term. The absence of a formal demand from the government does not excuse non-compliance.

• Quantum meruit has limits. While contractors who render services without a valid contract may recover the reasonable value of their services to prevent unjust enrichment, they cannot claim the full contract price. The government is only liable for actual costs incurred.

• Government officials must be vigilant. Officials who process payments without a valid contract risk personal liability. Section 106 of Presidential Decree No. 1445 requires accountable officers to notify their superiors in writing of any illegal or irregular transaction to be relieved from liability.

• Public bidding is mandatory. Republic Act No. 9184 requires government procurement to be done through competitive public bidding. No amount of good faith or public interest can substitute for this statutory requirement.

• Reliance on superior's instructions is not a defense. Following a superior's directive does not automatically excuse an accountable officer from liability, especially if the officer failed to document any written objection to the irregular transaction.
