G.R. Nos. L-70332-43 November 13, 1986
Generoso Trieste, Sr., petitioner, vs. Sandiganbayan (Second Division), respondent.

FACTS

Petitioner Generoso Trieste, Sr., the Municipal Mayor of Numancia, Aklan, was convicted by the Sandiganbayan of twelve counts of violating Section 3(h) of the Anti-Graft and Corrupt Practices Act ( Republic Act No. 3019 ). The Informations alleged that between July and October 1980, in his official capacity as Mayor and member of the Committee on Award, he approved payments for construction materials purchased by the municipality from Trigen Agro-Industrial Development Corporation, a company in which he was president, incorporator, director, and major stockholder. The transactions, totaling P7,730.50, were processed through various municipal vouchers which he signed. The Sandiganbayan sentenced him to imprisonment and perpetual disqualification from public office.
In his appeal, Trieste argued through a supplemental petition that he did not intervene in the awards, as the purchases were emergency direct transactions made via personal canvass by municipal personnel before his involvement. He signed the vouchers only after the materials had been delivered and paid for by the Municipal Treasurer. Crucially, the Office of the Solicitor General, representing the People, reassessed its position and filed a Consolidated Comment recommending acquittal. It found no evidence that Trieste used his official influence to secure the transactions for Trigen, noting the company had dealt with the municipality even before his mayorship and its offers were the lowest and most advantageous.

ISSUE

Whether petitioner Generoso Trieste, Sr. is guilty of violating Section 3(h) of R.A. No. 3019 , which prohibits a public officer from having financial interest in any business, contract, or transaction in connection with which he intervenes or takes part in his official capacity.

RULING

No. The Supreme Court reversed the Sandiganbayan’s decision and acquitted Trieste. The legal logic hinges on the essential elements of the offense under Section 3(h). For a conviction, two elements must concur: (1) the public officer has a direct or indirect financial or pecuniary interest in a business, contract, or transaction; and (2) he intervenes or takes part in his official capacity in connection with that same interest. While the first element was present due to Trieste’s ownership interest in Trigen, the second element was not proven. The Court, adopting the Solicitor General’s analysis, found no evidence of actual intervention. The transactions were emergency purchases made through direct canvass by municipal officials, with Trigen’s prices being the most reasonable. Trieste’s act of signing the vouchers constituted a ministerial duty performed after the fact of purchase and payment, not an act of intervention to secure the contract for his company. The law aims to prevent the use of official influence; its violation requires active participation in the transaction where the interest exists. Mere signing of disbursement documents, absent proof of influencing the award, does not constitute the prohibited intervention. Therefore, the absence of the second element warranted acquittal.
