When Government Transactions Can Be Disallowed: COA's Power Explained

The Commission on Audit (COA) has the constitutional power to examine government funds and disallow irregular expenditures. But this power has limits. In a 2024 ruling, the Supreme Court clarified that COA cannot disallow a payment merely because of internal procedural lapses — especially when the government actually received value for what it paid.

The case of Biong v. Commission on Audit (G.R. No. 258510, May 28, 2024) involved disallowed payments by the Philippine Health Insurance Corporation (PhilHealth) Region III to a supplier of printer inks and toners. The decision provides important guidance on when disallowances are proper and when they are not.

The Facts of the Case

PhilHealth Region III purchased office supplies from Silicon Valley under several purchase orders. When the Comptrollership Unit found that no Inspection and Acceptance Reports (IARs) existed for the deliveries, payments were withheld. The Audit Team Leader suggested that alternative documents could be attached to the disbursement voucher instead.

PhilHealth attached certifications from its General Services Unit, Supplies Withdrawal Slips, and Monthly Reports of Supplies and Materials Inventory. Payments were then released to Silicon Valley.

Later, the GSU Head discovered theft of office supplies and falsification of documents. The COA issued Notices of Disallowance against PhilHealth officers, including the GSU Head, for the payments made to Silicon Valley.

The Issue

The central question was whether COA committed grave abuse of discretion in upholding the disallowances based on: (1) delayed delivery by the supplier, (2) lack of IARs, and (3) falsified internal documents.

The Ruling

The Supreme Court ruled in favor of the petitioner, setting aside the disallowances. The Court held that COA gravely abused its discretion.

First, the 15-day delivery period was a mere contract stipulation, not an established rule. The supplier's delay was a breach of contract that triggered the penalty clause — not a ground for disallowance. The supplier had delivered all items and paid the corresponding penalties.

Second, the lack of IARs was an internal procedural lapse by PhilHealth. Citing Theo-Pam Trading Corp. v. Bureau of Plant Industry, the Court held that a third-party supplier's right to payment cannot be conditioned on a government agency's compliance with its own internal rules. Sales invoices showing actual delivery and receipt were sufficient basis for payment.

Third, the falsified Supplies Withdrawal Slips occurred after the transactions were completed and were disconnected from the purchase orders in question. The office supplies were fungible goods — the COA offered no logical explanation for concluding that the falsified slips covered Silicon Valley's items rather than those of other suppliers.

The Limits of COA's Power

The Court emphasized that a disallowance is proper only when the irregularity transpires at the time the expenditure is incurred. If the irregularity occurs after the fact, or is disconnected from the transaction, disallowance is not warranted.

The Court also noted that COA overstepped its authority by effectively punishing the GSU Head through the disallowance. COA's audit powers do not include disciplinary powers over government employees — that belongs to the Civil Service Commission and the Ombudsman.

Significantly, COA had exempted the supplier from liability while requiring the officer to reimburse the full amount. The Court found this inequitable, especially since the government suffered no loss — it received the supplies it paid for.

Practical Takeaways

• COA disallowances require a causal connection. The irregularity must relate to the transaction being disallowed, not to unrelated internal problems.
• Internal procedural lapses do not defeat valid obligations. A government agency cannot use its own failure to follow internal rules as a reason to avoid paying a supplier who delivered goods.
• Contract violations are not automatically audit irregularities. A supplier's delay in delivery may trigger penalty clauses, but it does not necessarily make the expenditure irregular.
• COA cannot impose penalties through disallowances. Its role is to ensure government funds are properly spent, not to discipline public officers.
• Liability for stolen property is separate. An accountable officer's liability for lost government property is determined through relief-from-accountability proceedings, not through disallowance cases.
