Senate Impeachment Court set for cross-exam of NBI agent in Duterte threat case

The 92 or 93 days is not certain
Court spokesperson acknowledges the trial's timeline remains flexible as procedural complexities emerge.

In Manila, the Senate Impeachment Court entered its second phase as Vice President Sara Duterte's defense team prepared to cross-examine the prosecution's first witness — an NBI agent who had testified about alleged assassination threats made against President Marcos, the First Lady, and a former House Speaker. The trial, built around charges of grave threats against the nation's highest elected officials, is already revealing the tension between procedural rigor and the unpredictable rhythms of a complex legal proceeding. What unfolds in these chambers will test not only the evidence, but the institutions entrusted to weigh it.

  • The defense wasted no time challenging the NBI agent's credentials and the authenticity of key video and documentary evidence, signaling an intent to dismantle the prosecution's foundation before it is fully built.
  • A second prosecution witness, NBI agent Jeremy Lontoc, stood ready to testify the same day if cross-examination concluded quickly — injecting a rare note of urgency into proceedings that could easily stretch and stall.
  • The court's projected 92-day trial timeline is already being treated as provisional, with the spokesperson openly acknowledging that procedural realities, not fault, may force extensions.
  • The charges at the center of the trial — that a sitting Vice President threatened to assassinate the President and his family — carry a gravity that keeps the proceedings under intense national scrutiny.
  • The court is attempting to absorb incidental oral arguments into an already compressed calendar, navigating the collision between formal legal constraints and the unpredictability of live proceedings.

The Senate Impeachment Court moved into its second phase on Wednesday, July 8, as Vice President Sara Duterte's legal team prepared to cross-examine NBI Senior Agent John Mark Calilung — the prosecution's opening witness in a trial centered on allegations that she made assassination threats against President Ferdinand Marcos Jr., First Lady Liza Araneta-Marcos, and former House Speaker Martin Romualdez.

Calilung had spent Tuesday delivering testimony on Article IV of the impeachment charges, marking the prosecution's first substantive presentation of evidence. Throughout, Duterte's defense team challenged both his credentials and the authenticity of the documents and video evidence he was asked to verify — objections that did not prevent him from completing his account.

Court spokesperson Atty. Regie Tongol noted that if cross-examination moved quickly, the prosecution could call its second witness, NBI agent Jeremy Lontoc, the same day. He also acknowledged that the court's initial 92-day timeline was not fixed. "Because of exigencies," he explained, "the court will necessarily extend the trial dates as may be" — a candid admission that formal schedules often bend under the weight of procedural reality.

The charges themselves are serious: Article IV alleges that Duterte made grave threats of assassination against a sitting president and his family. The defense's aggressive early posture suggested a strategy of undermining the prosecution's factual foundation from the outset. As the trial's second day of substantive proceedings unfolded, much remained uncertain — but what was clear was that the allegations at its center would receive a full airing before the Senate.

The Senate Impeachment Court moved into its second phase on Wednesday, July 8, as Vice President Sara Duterte's legal team prepared to cross-examine the prosecution's opening witness—NBI Senior Agent John Mark Calilung—in a trial centered on allegations that she made assassination threats against President Ferdinand Marcos Jr., First Lady Liza Araneta-Marcos, and former House Speaker Martin Romualdez.

Calilung had spent the previous day, Tuesday, July 7, delivering testimony before the court on Article IV of the impeachment charges. His appearance marked the prosecution panel's first substantive presentation of evidence in what is shaping up to be a lengthy and procedurally complex proceeding. Throughout his testimony, Duterte's defense team repeatedly challenged both his credentials as an investigator and the authenticity of the documents and video evidence he had been asked to authenticate—objections that did not prevent him from completing his full account.

Court spokesperson Atty. Regie Tongol indicated that the cross-examination could move quickly enough to allow the prosecution to call its second witness, NBI agent Jeremy Lontoc, on the same day. If the defense opted to forgo questioning, Tongol noted, the prosecution would simply advance to its next witness. The pace of the trial, however, remained uncertain. Tongol acknowledged that the court's initial projection of a 92-day trial timeline was not fixed in stone. "Sometimes the court will schedule a specific 92 days," he explained, "but because of exigencies or this instance, which both parties are not at fault, and it's also not the fault of the court, but just as part of court management, the court will necessarily extend the trial dates as may be."

The flexibility reflected a broader reality: impeachment trials operate within formal constraints that often collide with the unpredictability of witness schedules, legal arguments, and procedural disputes. Tongol said the court would attempt to fit incidental oral arguments into the existing trial calendar, though he offered no guarantee of success. The 92 or 93 days initially projected, he stressed, remained provisional.

The charges themselves carry significant weight. Article IV alleges that Duterte made grave threats of assassination against the sitting president and members of his immediate family—claims serious enough to form part of a formal impeachment proceeding. The NBI's investigation had apparently produced video and documentary evidence that Calilung was brought in to verify and explain. The defense team's aggressive questioning of his credentials and the evidence itself suggested they intended to undermine the prosecution's factual foundation from the outset.

As the trial entered its second day of substantive proceedings, the shape of the coming weeks remained largely undefined. The court faced the dual challenge of moving the case forward efficiently while accommodating the legitimate procedural rights of both sides. Whether Calilung's cross-examination would be brief or protracted, whether the second witness would appear the same day, and how many additional delays might accumulate remained open questions. What was certain was that the trial would continue, and that the allegations at its center—threats against the nation's highest elected officials—would receive a full airing before the Senate.

Why does the defense keep objecting to Calilung's credentials if he's already testifying?

Model

Because if they can undermine him as a witness—show he wasn't qualified to verify evidence, or that he mishandled it—then everything he says becomes suspect. It's not about stopping him from speaking. It's about poisoning the well for the judges.

Inventor

And the 92-day timeline—is that actually binding?

Model

No. It's a projection, a best guess. But impeachment trials are formal proceedings with rules. Both sides have rights to present evidence, cross-examine, file motions. If either side needs time, the court has to grant it. So the calendar stretches.

Inventor

What happens if the cross-examination is short?

Model

Then they move to the next witness the same day. The prosecution wants momentum. They want to build their case before the defense has time to organize a counter-narrative.

Inventor

But the defense is already objecting constantly. Doesn't that slow things down?

Model

Yes, but there's a difference between objections during testimony and formal motions that halt proceedings. Objections get noted. The judges hear them. But the witness keeps talking unless the court sustains an objection and orders testimony struck.

Inventor

So what's really at stake in this cross-examination?

Model

Credibility. If the defense can make Calilung look careless or biased, the video and documents he authenticated become questionable. And if the physical evidence is questionable, the entire case against the Vice President weakens.
