G.R. No. 149175 - Domingo vs. Sandiganbayan

Petitioners Jaime H. Domingo and Diosdado T. Garcia were prosecuted for violation of Section 3(h) of Republic Act No. 3019 (Anti-Graft and Corrupt Practices Act).
Jaime H. Domingo was the Mayor of San Manuel, Isabela, serving his third term when the petition was filed. He was unseated in November 1993 but re-elected in 1995.
Diosdado T. Garcia was the proprietor of D.T. Garcia Construction Supply and godson-in-law of Domingo.

During Domingo’s incumbency in 1993, a Multi-Purpose Pavement (MPP) project was undertaken in San Manuel for paving barangay roads, with an allocated budget of ₱520,000 from the 20% Economic Development Fund (EDF).
Congressman Faustino Dy, Jr. donated 3,600 bags of cement to be divided among the barangays.
The municipality subsidized gravel and sand costs through the EDF; barangays supplied labor.
An audit conducted by the Commission on Audit (COA) from June 13-17, 1994, revealed issuance of three checks related to gravel and sand supply:

PNB Check No. 901362 (₱264,350) payable to D.T. Garcia Construction but indorsed to municipal treasury and encashed to replenish Domingo’s cash advances.
PNB Check Nos. 901363 and 901365 (₱114,350 and ₱20,000 respectively) issued in Domingo’s name despite the voucher indicating payment to Garcia’s company.

No contract or agreement existed between the municipality and D.T. Garcia Construction Supply.
Procurement rules, including public bidding, were violated.
Disbursement vouchers and supporting documents were inadequately accomplished and lacked validation.
Contractor did not post performance bond.
Canvass papers were improperly filled.
Discrepancies existed between purchase orders and canvass sheets.
Certification from Municipal Engineer Edwin A. Abarra stated that dump trucks used to haul materials were owned by Domingo.
Documents showed D.T. Garcia Construction Supply sold the materials, but payments were made to Domingo.

Domingo was charged with violating Section 3(h) of R.A. No. 3019 for having financial interest in a municipality transaction. Garcia was later impleaded as co-accused for conspiracy.
Garcia initially supported Domingo’s defense claiming the contract was between his firm and the municipality and the payments issued to Domingo were to settle his mother’s indebtedness to Domingo's wife.
When the prosecution moved to discharge Garcia as state witness, this was denied, and Garcia reverted to contesting the existence of any contract and his involvement.
The prosecution argued Domingo used Garcia as a dummy to conceal his interest in the transaction.
Defense presented:

Purported contract dated May 10, 1993, between municipality and D.T. Garcia Construction.
Certificate of Emergency Purchase dated May 7, 1993, to justify non-observance of public bidding.
Testimonies of witnesses supporting Anicia Garcia’s indebtedness.
Statements from municipal officials corroborating contract and payment processes.

Garcia denied the existence of contract and outstanding indebtedness and claimed forgery of authorization letters.
Sandiganbayan found Domingo guilty, concluding the contract was fabricated and that Domingo had a financial interest that violated the Anti-Graft Law. Garcia was found a conspirator.

Garcia argued for conviction as accessory, not co-principal; Domingo challenged sufficiency of evidence.
Motions denied by Sandiganbayan.
Petitions for review were filed with the Supreme Court.

Whether petitioners Domingo and Garcia are guilty beyond reasonable doubt of violating Section 3(h) of Republic Act No. 3019.
Whether Garcia was a co-principal in conspiracy or merely an accessory after the fact.
Whether the findings of the Sandiganbayan committing petitioners to conviction were supported by substantial evidence.
Whether the Sandiganbayan erred in denying motions for reconsideration and in evaluating the evidence presented.
