G.R. No. 237330 - Madreo vs. Bayron

The case involves consolidated petitions for review in which petitioners Nestor A. Bernardino, Celedonia N. Tomas, and Eugelio G. Barawid, among others, were charged with falsification of public documents under Article 171, paragraph 2 of the Revised Penal Code.
The falsification allegation centers on documents that purportedly recorded a public bidding held on December 8, 1997, by the Prequalification Bid and Awards Committee (PBAC) of the Municipal Government of Guimba, Nueva Ecija, for the construction of an extension of the public market.

Petitioner Nestor A. Bernardino served as the former Municipal Mayor of Guimba and the Chairman of the PBAC for the project.
Petitioner Celedonia N. Tomas acted as the Secretary of the PBAC and was responsible for signing the Minutes of the Opening of Bids.
Petitioner Eugelio G. Barawid, the Municipal Treasurer, was a member of the PBAC.
Other members of the PBAC included municipal officials and representatives such as Ernesto T. Mateo, Benito A. Rillo, Efren N. Fronda, Abraham P. Coloma, Jose F. Mateo, Renato L. Esquivel, and NGO representatives Paulino G. Quindara and Luis F. Rendon, Jr.

Documents at issue included the “Minutes of the opening of bids”, a “Prequalification Bid and Award Committee” resolution, and the “Abstract of Proposal” as well as “Abstract of Bidding”.
These documents purportedly reflect that on December 8, 1997, the PBAC convened, evaluated four bidders, and, with the presence of a COA representative (Rolando E. Ronquillo), successfully conducted a public bidding awarding the contract to Mascom Design and Engineering International.
Petitioners and the PBAC members signed these documents even though later testimonies and affidavits indicated that no public bidding was actually conducted on the stated date.

After a change in municipal leadership (with Mayor Jose Lucius Pocholo Dizon succeeding in the May 1998 elections), a public bidding was conducted for the same project and awarded to another contractor (KYRO Builder).
Prosecution evidence relied heavily on the affidavits executed on June 27, 2000 by several PBAC members (e.g., Luis F. Rendon, Jr., Paulino G. Quindara, Renato L. Esquivel, Jose F. Mateo, Ernesto T. Mateo, Efren N. Fronda, and Abraham P. Coloma, Jr.) asserting that no public bidding was carried out on December 8, 1997.
Testimonies from COA representative Ronquillo and Mayor Dizon revealed that both admitted having no personal knowledge about an actual bidding on that day.
The prosecution also introduced further evidence including later affidavits (from 2003 to 2005) by some PBAC members in connection with a separate administrative case, wherein these affiants claimed a public bidding had indeed been held; however, these later affidavits were presented after the promulgation of the original decision and were used by petitioners as a ground for new trial.

The Sandiganbayan convicted the petitioners and other PBAC members on September 19, 2005, finding them guilty of falsification based on the affidavits and testimonies which indicated that no public bidding was held.
Separate motions for new trial were subsequently filed by petitioners—in particular, Bernardino and Tomas based on the later affidavits—and by Barawid along with other PBAC members on alleged legal errors and irregularities during the trial.
The Sandiganbayan denied the motions for new trial on November 18, 2005, and the case eventually reached the Supreme Court on review.

Whether the evidence presented by the prosecution, particularly the affidavits and testimonies, was sufficient to prove beyond reasonable doubt that a public bidding was conducted on December 8, 1997.
Whether the absence or failure of certain PBAC members to attend any actual bidding could conclusively establish that the PBAC, including petitioners Bernardino and Tomas, participated in a fraudulent act.

Whether the acts attributed to the PBAC members, including the signing of documents under false pretenses, could be considered a conspiracy and whether such conspiracy was proven by clear and positive evidence.
Whether the individual roles and actions of the petitioners—especially that of petitioner Tomas who signed the Minutes specifically mentioning the attendance of a COA representative—rendered them liable for falsification despite the conflicting affidavits and lack of personal knowledge among some affiants.

Whether the presumption of innocence should prevail due to the existence of conflicting evidence and the lack of moral certainty regarding the commission of the alleged falsification.
