A government prosecution panel finds an "interconnected network" of officials who manipulated project budgets and rigged bids, funneling public infrastructure funds to private interests.
The Department of Justice (DOJ) has recommended the filing of plunder and graft charges against Senator Jinggoy Ejercito Estrada and seven former and current officials of the Department of Public Works and Highways (DPWH), the Office of the Ombudsman (OMB) announced on Monday, May 18, 2026 — the most significant legal escalation yet in the sprawling flood control corruption scandal that has paralyzed government infrastructure spending for nearly a year.
Assistant Ombudsman Mico Clavano told reporters that the OMB received a DOJ resolution approving the filing of charges against Estrada and his co-respondents following a comprehensive preliminary investigation conducted by a DOJ panel in coordination with the Public Works and Bid-Rigging Task Force and the National Bureau of Investigation (NBI).
The Charges
The DOJ panel found probable cause to indict the respondents for plunder, violations of the Anti-Graft and Corrupt Practices Act, direct bribery, and corruption of public officials. Plunder — which under Republic Act 7080 requires proof that a public officer amassed ill-gotten wealth of at least ₱50 million — carries a maximum penalty of life imprisonment.
Named alongside Estrada in the DOJ resolution are:
- Former DPWH Secretary Manuel Bonoan
- Former DPWH Undersecretary Roberto Bernardo
- DPWH National Capital Region Regional Director Gerard Opulencia
- Former Bulacan District Engineer Henry Alcantara
- Assistant District Engineers Bong Dinglasan and Denryl Caesar Cortuna
- South Manila District Engineer Manny Bulusan
- DPWH official Arturo Gonzales Jr.
Former DPWH Undersecretary Maria Catalina "Cathy" Cabral — whose name had featured prominently in congressional testimony about the anomalies — was dropped from the charges due to her death, Clavano noted.
What the DOJ Panel Found
According to Clavano, the panel concluded that the respondents formed "an interconnected network of public officers who abused their official designations to manipulate project specifications, clear budgets, and rig public bidding workflows."
"Multiple high-ranking public officials and private individuals conspired to maneuver allocations, rig public bidding processes, and siphon government funds stemming from major national infrastructure systems," the Ombudsman official said, summarizing the DOJ panel's key findings.
Clavano said the resolution was released after the DOJ panel conducted a comprehensive preliminary investigation that included counter-affidavits and extensive evidence-gathering over several months. The resolution has been transmitted to the Office of the Ombudsman, which will conduct its own independent evaluation before deciding whether to affirm, modify, or reverse the DOJ's recommendations and file formal charges before the Sandiganbayan.
Estrada's Link to the Flood Control Network
Senator Estrada — son of former President Joseph Estrada and a senator since 2013 — had been linked to allegations of receiving kickbacks from contractors tied to flood control projects in the National Capital Region and nearby provinces. A contractor testified in a Senate inquiry in September 2025 that cash was delivered to Estrada's associates, an allegation Estrada denied, saying "Walang ganun" (Nothing like that happened).
The DOJ resolution's plunder finding, if upheld by the Ombudsman and filed before the Sandiganbayan, would make Estrada ineligible to continue serving in the Senate pending the resolution of the case, depending on how courts rule on suspension orders.
The charges against Estrada come as his close ally, former Senator Ramon "Bong" Revilla Jr., is already in Sandiganbayan detention facing separate charges in the flood control mess, in a case filed by the Ombudsman in January 2026 over ghost projects in Bulacan.
Bonoan's Defense and the DBM Context
Former DPWH Secretary Manuel Bonoan, who led the agency during the period when billions in flood control funds were allegedly misused, has denied any wrongdoing. His departure from the DPWH in late 2025 set off a chain of Cabinet reshuffling that the Marcos administration has been managing even as public scrutiny of the department has intensified.
The flood control scandal has been estimated by Finance Secretary Ralph Recto to have cost the Philippine economy as much as ₱118 billion (approximately US$2.4 billion) between 2023 and 2025 in anomalous ghost projects and substandard construction. Government infrastructure spending has contracted for three consecutive months in 2026 — down 43.5 percent in the first quarter — as the DPWH struggles with stricter billing validation and public confidence questions.
What Happens Next
The Ombudsman is not bound by the DOJ resolution. It will independently review the evidence before deciding whether to file information before the Sandiganbayan. Clavano gave no timeline for when the Ombudsman would complete its evaluation. In past high-profile cases, the process has taken weeks to months.
Neither Estrada's office nor Bonoan had issued a formal response to the charges at time of writing.
Context
The DOJ panel's recommendation is the latest in a series of escalating legal actions tied to the flood control scandal. The Ombudsman had previously filed graft complaints against Revilla in January 2026 and against Camarines Sur Representative Arnulf Bryan Fuentebella in May 2026 over collapsed flood control structures in his district. The scandal triggered a broader COA and NBI investigation into public works procurement practices going back to 2023, and has become a central issue in Vice President Sara Duterte's impeachment proceedings, where the alleged misuse of confidential and DPWH-adjacent funds featured in House testimony.
Republic Act 7080 (Plunder Law) requires conviction of at least two predicate acts constituting ill-gotten wealth of no less than ₱50 million. Plunder is a non-bailable offense when the evidence of guilt is strong.
