The Department of Justice has recommended the filing of plunder and graft charges against Senator Jinggoy Estrada and former Department of Public Works and Highways (DPWH) Secretary Manuel Bonoan, escalating the government's accountability drive in one of the largest public-funds scandals in recent Philippine history.
The Office of the Ombudsman confirmed on Monday, May 18 that it officially received the DOJ resolution, which now awaits the Ombudsman's own independent review before any cases are formally filed in the Sandiganbayan.
"The Office of the Ombudsman confirms that our office has officially received a copy of the Resolution from the Department of Justice National Prosecution Service regarding NPS Docket No. XVI-INV-26A-00003," Assistant Ombudsman Mico Clavano said at a press briefing.
What the DOJ Found
According to Clavano's summary of the DOJ resolution, investigators allege that "an interconnected network of public officers abused their official designations to manipulate project specifications, clear budgets, and rig public bidding workflows" in connection with regional flood control projects under the fiscal year 2025 General Appropriations Act.
The case was initiated by the NBI-DOJ Public Works and Bid-Rigging Task Force following a preliminary investigation into alleged anomalies in legislative and public works budget execution. Prosecutors allege that officials and private contractors conspired to maneuver budget allocations through the Bicameral Conference Committee and the House General Appropriations Bill, siphoning government funds through the National Expenditure Program.
The DOJ panel said it found evidence of alleged "illicit maneuvers" and "30-percent cuts" connected to regional flood control projects — a reference to reported kickback arrangements in which contractors returned a portion of the contract value to officials who facilitated awards.
Who Is Named
The primary respondents named in the DOJ resolution are:
- Senator Jinggoy Estrada, a former senator currently serving his third term
- Former DPWH Secretary Manuel Bonoan
- Former DPWH Undersecretary Roberto Bernardo
- The late former DPWH Undersecretary Maria Catalina "Cathy" Cabral (charges against her were dropped following her reported death on December 19, 2025)
- Gerard P. Opulencia, DPWH National Capital Region Regional Director
- Henry C. Alcantara, DPWH District Engineer for Bulacan's First District
- Several other DPWH officials and private individuals including Bong Dinglasan, Denryl Caesar Cortuna, Manny Bulusan, and Arturo Gonzales Jr.
Estrada rejected the findings, calling the recommended charges "baffling and unjust," according to The Manila Times. His office has not issued a detailed rebuttal of the specific allegations in the DOJ resolution.
Charges Sought
The DOJ recommended charges under four statutes: plunder under Republic Act 7080; graft under Sections 3(b) and 3(e) of the Anti-Graft and Corrupt Practices Act (RA 3019); direct bribery under Article 210 of the Revised Penal Code; and corruption of public officials under Article 212 of the Revised Penal Code.
Three DPWH officials — Bernardo, Opulencia, and Alcantara — were granted coverage under the DOJ's Witness Protection, Security and Benefit Program in exchange for their cooperation, and the DOJ recommended they be excluded from the final criminal information to be filed in court. The resolution also called on the NBI-DOJ Task Force "to pursue further investigation to fully unmask the identity of the remaining John and Jane Does who acted as intermediaries or beneficiaries in the project allocations."
Ombudsman's Next Steps
Clavano stressed that the Ombudsman's receipt of the DOJ resolution does not mean charges will automatically be filed. The office will conduct its own independent evaluation, with possible outcomes including affirming, amending, or reversing the DOJ's findings altogether.
"Moving forward, the next step will be to allow the Office of the Ombudsman to conduct its own independent review and resolution on the merits of the case," Clavano said.
Context: Scale of the Flood Control Scandal
The flood control corruption investigation is among the most sweeping in the Marcos administration's anti-corruption drive. As of April 30, 2026, the Anti-Money Laundering Council had frozen more than P21.8 billion in assets linked to the scheme, according to Senate blue ribbon committee chair Senator Panfilo Lacson.
Investigators have identified 421 ghost projects among approximately 8,000 flood control contracts reviewed, and flagged more than P350 billion worth of contracts with vague descriptions or near-identical designs as potentially fraudulent or templated. Separate cases involving former senator Bong Revilla and Ako Bicol representative Zaldy Co are already pending before the Sandiganbayan, and the Sandiganbayan has upheld the denial of bail for several DPWH executives already charged in earlier tranches of the case.
The Estrada-Bonoan case marks a significant escalation: it is the first tranche implicating a sitting senator and a cabinet-level official by name.
