Government Procurement and Audit Disallowances: Lessons from a Landmark COA Ruling

The Supreme Court's 2020 decision in De Castro v. Commission on Audit (G.R. No. 228595) offers important guidance for local government officials, contractors, and auditors navigating the often-conflicting rules on government procurement and post-audit disallowances. The case arose from the construction of the Bulan Integrated Bus Terminal and Slaughterhouse in Sorsogon, where the Commission on Audit (COA) issued several Notices of Disallowance (NDs) against municipal officials and private contractors. The ruling clarifies when public officers may be personally liable for disallowed expenditures and underscores the high bar for overturning COA findings.

The Facts of the Case

In 2003, the Sangguniang Bayan of Bulan, Sorsogon authorized a bond flotation of up to P50 million to fund the construction of a public bus terminal, a new municipal slaughterhouse, and other priority projects. In October 2006, the municipal government conducted public biddings and awarded contracts to S.R. Baldon Construction & Supply for the bus terminal (P32,984,700.00) and to Steven Construction & Supply for the slaughterhouse (P4,991,800.00).

Following a special audit, COA issued several NDs disallowing portions of the payments. The grounds included: (1) an unaccomplished deficiency of 0.58% in the bus terminal; (2) an alleged overprice of 16.79% net of the allowable variance; (3) liquidated damages for delays in both projects; and (4) the nullification of both contracts for failure to post the procurement opportunities on the PhilGEPS website, as required by the Implementing Rules and Regulations (IRR) of Republic Act No. 9184 (Government Procurement Reform Act).

The Issues Raised

The petitioners—the former mayor, municipal engineer, BAC chairman, and other officials—raised several procedural and substantive objections. They claimed that COA committed grave abuse of discretion by: disallowing amounts based on wrong legal authority; applying unpublished DPWH equipment rental rates; failing to resolve their appeals on time; and holding officials liable despite the lifting of certain NDs. They also argued that the NDs were defective for failing to cite specific laws violated.

The Supreme Court's Ruling

The Court denied the petition, affirming COA's decision with modification. While the Court relaxed the procedural rules to entertain the petition—finding prima facie merit in some arguments—it ultimately upheld COA's findings on the merits.

On procedural due process. The Court held that the NDs were sufficient to comply with administrative due process. The notices contained the reasons for disallowance with references to supporting documents, which adequately informed the parties of the basis for the disallowance and allowed them to formulate their defenses. The Court also rejected the claim that COA's failure to discuss every individual argument in the motion for reconsideration amounted to a due process violation, noting that tribunals are not required to resolve all issues raised unless necessary.

On the right to speedy disposition. The Court acknowledged that the right to speedy disposition applies to all parties before quasi-judicial bodies, including COA. However, it emphasized that this right is relative and flexible—a mere mathematical reckoning of time is not enough. Weighing the length of delay against the need for thoroughness in examining six disallowances involving complex technical issues, the Court found the delay not inordinate.

On the modification of disallowances. The Court held that COA is not limited to reviewing only the grounds relied upon by the auditor. It is duty-bound to make its own assessment of the merits of a disallowed disbursement. Thus, when the original ND for the unaccomplished deficiency was modified to reflect liquidated damages for delay, this was permissible—both grounds stemmed from the same cause: the contractor's failure to install the required 50kva transformer within the contract time.

On the liability of public officials. The Court upheld the disallowance against the mayor for issuing a work suspension order without legal basis, which caused the delay in the bus terminal project. It also held the municipal engineer liable for giving inconsistent and misleading information regarding the completion date of the slaughterhouse project.

Practical Takeaways

• Public officials can be personally liable for disallowed amounts. The Court affirmed that officials who issue baseless suspension orders or provide misleading information may be held personally liable for resulting disallowances, even if the underlying contract was valid.

• COA has broad authority to modify disallowances on appeal. An ND may be modified to reflect a different ground, as long as the new ground is subsumed in the original cause. Officials and contractors should not assume that a change in the stated reason invalidates the disallowance.

• PhilGEPS posting is mandatory. While the Court lifted the NDs nullifying the contracts for failure to post procurement opportunities on PhilGEPS, it did so "for want of legal basis"—but it did not condone the violation. It expressly noted the administrative liability of the head of the procuring entity and BAC members for violating RA 9184 and its IRR.

• Procedural due process in audit proceedings is flexible. COA notices need only provide sufficient information for the party to respond and defend. Failure to cite a specific statute in the ND does not automatically render it defective.

• The right to speedy disposition is not measured by mere delay. Courts weigh the length of delay, the reasons for it, and the prejudice caused. Complex audit cases may justify longer resolution periods.
