Ombudsman Jesus Crispin Remulla said on Tuesday that the agency is preparing two criminal cases against former House Speaker Martin Romualdez, including allegations of money laundering and what he called the “grandest case” of conspiracy to defraud the national treasury.

“Nandyan na yan. Meron kaming dalawa pang kaso na hinahanda tungkol diyan. Meron kaming isa pang money laundering case, mabigat at of course, the grandest case of them all, ang pinakamabigat na kaso diyan, yung conspiracy to defraud the treasury,” Remulla said during a press briefing.

He added that the case would be unprecedented in the country’s legal history, noting that investigators are proceeding cautiously due to its scope and complexity.

“Hindi madaling ilatag iyan. We're being very careful about every premise that we make kasi first time ito gagawin sa kasaysayan ng Pilipinas na magkakaroon tayo ng ganitong klaseng kaso,” Remulla said.

Remulla also said there is no timetable for the filing of the cases.

“Wala kami timetable dyan. Basta yung big case kasi, hindi mo pwede lagyan ng timetable ‘yan. Kinakalap namin ang ebidensya ‘yan. Binubuo namin sa araw-araw. Kaya we're here everyday. We just go to work everyday. Marami naman. It's bearing fruit. Marami naman kami nakukuha ang ebidensya,” he said, adding that investigators continue to obtain supporting materials.

Romualdez has been linked to allegations in connection with the flood control scandal.

He has previously denied the accusations against him.
