MANILA (UPDATED) — The eldest son of Justice Secretary Jesus Crispin “Boying” Remulla has been transferred to the Las Piñas City Jail in relation to drug charges, an official said Wednesday.

Juanito Jose Remulla III was caught with suspected high-grade marijuana or kush worth P1.3 million during a controlled delivery conducted by an inter-agency task force in Las Piñas City last Oct. 11.

The younger Remulla was transferred to the Las Piñas City Jail from the custody of the Philippine Drug Enforcement Agency (PDEA) on Nov. 4, said Bureau of Jail Management and Penology — National Capital Region spokesperson Sr. Insp. Hernand Macoy.

Remulla III has been charged with violating Section 11 of the Comprehensive Dangerous Drugs Act of 2002.

He pleaded not guilty to drug possession charges during the arraignment conducted by the Las Piñas Regional Trial Court through video conference on Nov. 4.

Meanwhile, his separate illegal drug importation case is already submitted for resolution.

Pasay Deputy City Prosecutor Joselito de Asas, who leads the special panel of prosecutors on Remulla’s drug raps, said the respondent waived his right to file a counter-affidavit during the preliminary probe on Wednesday.

This means that the preliminary investigation has been terminated and the prosecutors will study the case based on the evidence presented.

Remulla and his lawyer Jose Christopher “Kit” Belmonte attended the probe.

“Submitted na for resolution. Okay na ‘to. Wala na. Tapos na,” Belmonte told members of the press during an ambush interview.

(It has been submitted for resolution. It's okay, it's done.)

Remulla III's arrest prompted calls for his father's resignation, even among some lawmakers who questioned how impartial prosecutors could conduct probes under the watch of his agency, the Department of Justice (DOJ).

Secretary Remulla in October said leaving his post "is not my call" and that the decision rests on President Ferdinand "Bongbong" Marcos, Jr.

The elder Remulla had vowed not to intervene in his 38-year-old son's case.

Rulings of city and provincial prosecutors may be appealed to the Office of the Secretary of Justice for review. Remulla said his agency would not entertain any appeal on his son’s case.

“If there is a resolution, don't let it reach the DOJ. Let it be discussed in court, whatever the case may be,” he said. “If it’s an adverse case against my son, it will not be appealed here. It will go straight to the courts for trial.”
