This case clarifies the scope of authority and responsibility in government procurement processes. The Supreme Court affirmed that the Commission on Audit (COA) is not estopped by the actions of its resident auditor during public biddings. The primary responsibility for ensuring that bidding processes are above-board and advantageous to the government lies with the Bids and Awards Committee (BAC) of the procuring entity, not the COA auditor whose role is mainly to ensure documentary integrity and transparency. Ultimately, this ruling underscores the separation of powers and duties within government agencies regarding financial oversight and procurement.

Plastic Bags and Public Bids: Who’s Accountable When Prices Don’t Add Up?

The case of Director Fredric Villanueva, et al. v. Commission on Audit, G.R. No. 151987, decided on March 18, 2005, revolves around the alleged overpricing of polyethylene plastic bags purchased by the Department of Environment and Natural Resources-Cordillera Administrative Region (DENR-CAR). The petitioners, members of the Bids and Awards Committee (BAC) of DENR-CAR, were found by the COA to have made purchases without a proper public bidding, leading to an overprice of P316,138.50. The COA recommended filing criminal charges against the petitioners for violating Section 3(e) of Republic Act No. 3019, the Anti-Graft and Corrupt Practices Act.

The central legal question before the Supreme Court was whether the COA gravely abused its discretion in holding the petitioners liable for the alleged overprice, given the presence and participation of a COA resident auditor during the bidding process. Petitioners argued that they relied on the expertise of the COA representative, who did not object to the bidding process and even signed the minutes of the proceedings. The COA countered that its auditor’s role was limited to ensuring documentary integrity, with the ultimate responsibility for the fairness and accuracy of the bidding resting on the BAC members.

The Supreme Court upheld the COA’s decision, emphasizing the constitutional mandate of the COA to examine and audit the use of government funds on a post-audit basis. The Court referred to COA Circular No. 78-87, which delineates the functions of the auditor during the opening of bids. According to the circular, the auditor’s presence is primarily as a witness to maintain documentary integrity and physical security of bidding records. The circular explicitly states that the auditor’s presence is “as witness only” with specific functions delineated. The maintenance of documentary integrity involves properly identifying each document, while physical security means securing the records against tampering.

Building on this principle, the Supreme Court cited Danville Maritime v. Commission on Audit, stating that the COA representative’s role at the time of bidding was only as a witness to ensure documentary integrity. The Supreme Court also highlighted COA Circular No. 89-299, which lifted the pre-audit of government transactions. Pre-audit is an examination of financial transactions before their consumption or payment, ensuring compliance with laws and regulations, availability of funds, and reasonableness of the expenditure. By lifting pre-audit, the COA shifted the primary responsibility for financial oversight to the heads of government agencies. Thus, during the 1994 bidding in question, the COA auditor was not conducting a pre-audit but was merely present to ensure documentary integrity.

This approach contrasts with the duties of the BAC members, who, under the Administrative Code of 1987, are tasked with the “conduct of prequalification of contractors, bidding, evaluation of bids and recommending of awards of contracts.” The Supreme Court emphasized that the BAC members possess the technical expertise to determine the offers that best meet the needs of their office. Therefore, the burden rests on the agency calling for the bidding to ensure that the process is above-board and advantageous to the government. The Court acknowledged that the COA auditor’s presence serves to guarantee documentary integrity and transparency in the bidding process.

The petitioners raised the defense of good faith, claiming they relied on the COA auditor’s representations. The Supreme Court clarified that this argument is a matter of defense to be presented in the criminal case, if any, filed against the petitioners. The Court emphasized that the COA is not estopped from questioning the previous acts of its officials during post-audit, as estoppel does not lie against the government. Citing Development Bank of the Philippines v. Commission on Audit, the Supreme Court reiterated that the COA can question erroneous or irregular acts of its officials.

Even if plastic bags purchased were overpriced, Special Audit Team sufficiently studied and explained the matter of overpricing and that the audit team conducted a re-canvass, comparing the agency’s purchase price with the quotations of various suppliers and disclosed that the items purchased by the agency were overpriced. It was also noted that PBAC’s procedure of requiring the submission of at least (3) sealed quotations did not ensure the widest publicity needed for competitive bidding as they left it entirely to the canvassers the determination of which suppliers are to be served canvass quotations. With the limited publicity, the PBAC was not able to draw more bidders, resulting to overpricing.
