The impeachment trial of Vice President Sara Z. Duterte should move forward, as her response to the articles of impeachment failed to directly address the evidence and instead focused on seeking the case’s dismissal through procedural, technical, and constitutional objections, the House prosecution panel said on Tuesday.
Lanao del Sur Rep. Zia Alonto Adiong, spokesperson of the House prosecution panel, said on Tuesday that the prosecution sees no need to file an additional pleading, noting that the vice president’s submission was aimed at dismissal rather than a substantive contest of the charges.
‘There’s no need for the House prosecution to submit its pleading because technically, what they have been saying all along is questioning the procedure, the constitutionality of the entire process. So, we’ve heard that since last year, and we’ve been hearing that during the press conference of the defense team,’ Adiong said.
According to the prosecution, this approach shifts the focus of the case to the Senate impeachment court, where both parties are expected to present their arguments under formal trial rules.
‘So, there are no substantive arguments or counterarguments that they have actually supplied in their answers to the articles of impeachment. It was purely procedural and constitutional objections,’ Adiong said.
Adiong said the defense strategy appears aimed at securing an outright dismissal of the case before the evidence can be fully presented.
‘There is no point for the House prosecution team to respond to the Vice President’s answer. What her legal team is seeking is the outright dismissal of the case based on procedural, technical, and constitutional grounds,’ he added.
He also noted that the prosecution anticipates the defense will rely heavily on technical objections once the trial formally begins.
‘It’s basically because of the non-answer, and so I would expect, and we would expect, that once the trial comes to a full-blown scenario, the House prosecution or the court itself would be hounded by a lot of objections, technical objections, since they don’t have anything to offer to counter the evidence of the prosecution. So, we would expect a lot of objections, motions to strike, et cetera,’ Adiong said.
The prosecution is now preparing for the pre-trial conference, where the Senate impeachment court is expected to establish the rules governing the presentation of evidence, witnesses, and other proceedings.
‘The next process would be the pre-trial conference. And I believe that the Senate has already indicated the dates for the pre-trial conference and for the actual impeachment trial, which would be on July 6, if I’m not mistaken,’ Adiong noted.
He explained that the pre-trial conference will allow the prosecution to formally submit its evidence and identify potential witnesses.
‘So, come next week; we are hoping, and we’re expecting, that the court will convene for the pre-trial conference so that the House Prosecution team will be able also to submit the evidence and also to submit the list of the names of our potential witnesses. So, basically, the pre-trial conference is laying down the ground rules for the people to know what the flow of the trial would be,’ Adiong added.
Procedural step
The Senate impeachment court has scheduled the pre-trial conference in the impeachment case against Vice President Duterte on June 18, 2026, marking a key procedural step ahead of the formal presentation of evidence and witnesses, House prosecutor Terry L. Ridon of the Bicol Saro Party-list said on Tuesday.
Ridon said a notice of a pre-trial conference issued on June 9 and signed by acting Senate President and Presiding Officer Sherwin Gatchalian directed Duterte and the House prosecution panel to appear before the impeachment court at 9 a.m. on June 18 at the Sen. C.M. Recto Room in the Senate.
The notice stated that both parties may appear personally or through counsel and are expected to tackle major pre-trial matters, including stipulation of facts, simplification of issues, marking of documentary and object evidence, identification of witnesses, scheduling of trial dates, and the order of presentation of evidence, among others to ensure an orderly and expeditious trial.
Ridon said the impeachment court also required both sides to submit their pre-trial briefs not later than June 15, which must include a summary of admitted facts, proposed stipulations, issues for resolution, and a list of available documents, exhibits, and witnesses.
The notice further requires parties intending to reserve evidence or witnesses to disclose their identities or describe the evidence and its purpose at least three days before presentation before the court.
For security considerations, the impeachment court allowed limited withholding of witness identities until actual presentation, provided they are included in the total number of witnesses and reflected in the trial schedule.
It also stated that the pre-trial conference will not be open to the media or the public in order to encourage candid discussions and facilitate the proceedings.
‘The pre-trial conference proceedings shall not be open to the media or public,’ the notice stated.
Ridon warned that failure to file the required pre-trial brief on time or absence without valid justification may result in the waiver of the right to present certain evidence or witnesses. He added that the court may proceed to issue a pre-trial order based on available records should any party fail to comply.
Ridon said the June 18 conference is expected to define the framework of the impeachment trial by narrowing issues, organizing evidence, and setting the timetable for the proceedings.
