G.R. Nos. 147773-74; February 18, 2008
DENNIS MANGANGEY, GABRIEL WANASON, and ANSELMO FORAYO, petitioners, vs. HONORABLE SANDIGANBAYAN (Fifth Division) and the PEOPLE OF THE PHILIPPINES, respondents.

FACTS

In 1986, the Municipality of Paracelis undertook a road project awarded to contractor Leon Acapen. Upon its purported completion, petitioners, all public officers, signed separate Certificates of Inspection and Acceptance dated December 8, 1986, attesting under oath that they had personally inspected the project and found it 100% completed in accordance with contract specifications. Based on these certifications, the government paid Acapen PhP 106,970. A subsequent Commission on Audit investigation, prompted by a complaint, revealed that for one major contract item there was zero accomplishment, and for another, only 365 cubic meters out of 4,010 cubic meters were actually accomplished.
Petitioners, along with Mayor Matthew Wandag and Acapen, were charged with Estafa through Falsification of Public Documents under Article 315, in relation to Article 171, of the Revised Penal Code. After a joint trial, the Sandiganbayan convicted petitioners, finding that they made untruthful statements in the certificates regarding their personal inspection and the project’s completion, which enabled the fraudulent payment. Petitioners appealed, arguing the prosecution failed to prove their guilt beyond reasonable doubt.

ISSUE

Whether the Sandiganbayan erred in convicting petitioners of the complex crime of Estafa through Falsification of Public Documents.

RULING

The Supreme Court affirmed the conviction. The legal logic rests on the established elements of falsification of public documents by a public officer under Article 171 of the RPC and the resulting estafa under Article 315. The Court found all elements present. Petitioners, as public officers, had a legal obligation to disclose the truth in the certificates they executed. The certifications contained two material untruths: first, that they personally inspected the work, and second, that the project was 100% complete. The COA report conclusively proved the gross discrepancy between the certified and actual accomplishments. These false assertions were not mere innocent mistakes but were essential to the scheme, as they were the direct cause for the release of government funds to the contractor for largely unperformed work, thereby defrauding the government. The defense of good faith and reliance on the contractor’s representations was rejected. As public officers tasked with inspection, they had a positive duty to verify the actual work before certifying its completion. Their failure to do so, resulting in the issuance of patently false certificates that facilitated the fraudulent disbursement, established their criminal liability for the complex crime.
