Accountability in Public Infrastructure: When COA Disallowances Become Final

The Supreme Court's 2021 ruling in Patdu, Jr. v. Commission on Audit (G.R. No. 218461) clarifies two important points for public officers involved in infrastructure projects: first, decisions of COA directors that lift disallowances can become final and immutable; and second, project engineers are not automatically civilly liable for disallowed amounts unless bad faith, malice, or gross negligence is shown.

The case arose from the construction of the Davao Fishing Port Complex, a foreign-assisted project funded by Japan's Overseas Economic Cooperation Fund. The Department of Transportation and Communications awarded the contract to the EEI/Manalo Joint Venture in 1993 for P347 million. During construction, the project engineer, Ildefonso Patdu, Jr., reviewed several variation orders that adjusted the original design and quantities of work.

The Disallowances and Their Reversal

In 1997, the COA Auditor issued Notice of Disallowance No. 97-011-102 (DOTC) (95), disallowing P53.9 million of the project cost. The COA's Special Task Force determined that the actual project cost exceeded the COA's estimated cost by that amount. A separate disallowance (ND No. 98-004-102) covered an excessive portion of an early completion incentive bonus.

The DOTC sought reconsideration, arguing that foreign-assisted projects are exempt from the auditorial review requirements under Presidential Decree No. 1594 and its implementing rules. The COA Auditor eventually recommended lifting the first disallowance, and the NGAO II Director sustained this recommendation in a 5th Indorsement dated July 19, 2001.

Finality of the Director's Decision

The critical question was whether the NGAO II Director's decision to lift the disallowance had become final. The Supreme Court ruled that it had.

Under Section 6, Rule V of the COA Revised Rules of Procedure, a director must elevate a decision to the COA Proper only when the director reverses, modifies, or alters the auditor's ruling. Here, the auditor recommended lifting the disallowance, and the director sustained that recommendation. Since both were in agreement, automatic review was not required, and the decision lapsed into finality.

The Court applied the doctrine of immutability of judgments, which applies to quasi-judicial bodies like the COA just as it does to courts. The COA Proper gravely abused its discretion when it reinstated the disallowance almost ten years later in a proceeding involving a different notice of disallowance.

When Are Officials Liable for Disallowed Amounts?

Even if the disallowance had been properly reinstated, the Court found that Patdu should not be held civilly liable. Under Sections 38 and 43 of the Administrative Code of 1987, as interpreted in Torreta v. Commission on Audit, approving and certifying officers are civilly liable only upon a clear showing of bad faith, malice, or gross negligence.

The COA merely stated that Patdu "failed to diligently review" the variation orders. It did not specify any acts or omissions amounting to bad faith, malice, or gross negligence. The Court noted that an act done in good faith that constitutes only an error of judgment is simple negligence, which is insufficient to impose civil liability.

The Court also acknowledged that variation orders are not automatically invalid. They are necessary adjustments to construction projects to suit actual field conditions, and Patdu provided justifications for the specific variation orders that were not rebutted by the COA.

Practical Takeaways

• COA directors' rulings can become final. When a COA director sustains an auditor's recommendation, that decision may attain finality if not appealed, and the COA Proper cannot later reverse it.
• Finality protects public officers. Once a disallowance is lifted and the decision becomes final, the State cannot resurrect the claim years later, even if the COA later adopts a different interpretation of the law.
• Good faith is a defense. Public officers who act in good faith and in the regular performance of their duties are presumed to have acted properly and are not civilly liable for disallowed amounts.
• Specific findings are required. To hold an approving or certifying officer liable, the COA must clearly show bad faith, malice, or gross negligence—not merely a failure to be diligent.
• Variation orders are legitimate. Adjustments to construction projects are permissible when they respond to actual field conditions and remain within the general scope of the project.
