The Witness Who Wasn’t: How Trillanes Ghosted Sara Duterte’s Impeachment Trial

The Cart, the Horse, and the Senator-Judge Who Wouldn’t Shut Up

By Louis ‘Barok‘ C. Biraogo — October 1, 2026

SPARE us the violin music: Antonio Trillanes IV is not a shrinking violet. This is a man who once staged a hotel mutiny, spent years in detention, and has made a second career out of accusing the Duterte family of hiding ill-gotten wealth. He does not do “quiet withdrawal.”

And yet, on October 1, 2026, Trillanes—the prosecution’s most anticipated witness in the impeachment trial of Vice President Sara Duterte—vanished from the witness list. Not with a bang, not with a courtroom showdown, but with a Facebook post and a promise of a press conference the next day.

Lead prosecutor Gerville Luistro told the Senate impeachment court, with what reporters described as a “somewhat regretful tone,” that the prosecution had “finally decided not to present former Senator Sonny Trillanes,” requesting “kind indulgence” for the “belated final decision.” Trillanes, in turn, said he asked to be dropped to relieve the prosecution of “the pressure it is going through.”

What pressure? From whom? And why does the prosecution need “indulgence” for a decision it supposedly made at its own witness’s request?

The answers, such as they are, tell us less about Trillanes than about the spectacular dysfunction of this impeachment proceeding.

The Cart, the Horse, and the Senator-Judge Who Wouldn’t Shut Up

The seeds of this debacle were planted days earlier, when the prosecution sought a subpoena for Trillanes. Presiding Officer Francis Escudero declined, delivering the trial’s most quotable line: “The cart cannot be put ahead of the horse.” Bank records and Anti-Money Laundering Council (AMLC) testimony, he ruled, must come before Trillanes’s interpretation of them. The court would not issue a subpoena, though it couldn’t stop the prosecution from calling him voluntarily.

Then Senator-Judge Raffy Tulfo intervened. Tulfo, apparently auditioning for the role of chief strategist, declared that Trillanes should testify before the AMLC—that the former senator should reveal his bank accounts first, and the AMLC would then confirm them. This was, on its face, a reasonable narrative strategy: Trillanes provides the story, the AMLC provides the corroboration.

But it directly contradicted Escudero’s procedural ruling. And Tulfo wasn’t subtle about his frustration with the prosecution’s broader performance. “Sometimes the prosecution—I’m sorry—you fail,” he said. “You present witnesses that are not really needed, you are just wasting time, you can see senators being sleepy, some go to the CR because listening seems to be useless.”

One prosecutor, San Juan Rep. Ysabel Maria Zamora, responded to online mockery of her questioning style by telling critics to “get a life.”

This is the caliber of legal theater we’re dealing with.

The AMLC Confirmation That Confirms Less Than You Think

Let’s revisit the evidentiary centerpiece. In April 2026, Trillanes appeared before the House Justice Committee with a sworn affidavit and annexes purporting to document billions of pesos flowing through accounts linked to the Duterte family. AMLC Executive Director Ronel Buenaventura then confirmed that 18 out of 18 randomly selected transactions from Trillanes’s annexes matched AMLC records.

Eighteen out of eighteen. That sounds devastating.

But here’s the analytical problem: “matching” a transaction to AMLC records establishes that the transaction occurred. It does not establish:

Who beneficially owned the account;
Whether the money was legally acquired;
Whether the transactions were deposits, transfers, withdrawals, or mere pass-throughs;
Whether the aggregate figure—₱6.77 billion—represents wealth or simply years of transaction volume.

As University of the Philippines (UP) Law Assistant Professor Michael Tiu noted, Trillanes’s testimony about the accounts could be attacked as hearsay—he lacks personal knowledge of how the accounts were opened or how the transactions occurred. More damningly, Tiu asked: “Does this witness come to the stand only bringing information? Or is there bias or is there some prejudice that already taints [the testimony]?”

Trillanes is, after all, a longtime political antagonist of the Dutertes. He filed crimes-against-humanity complaints against Rodrigo Duterte at the International Criminal Court (ICC). The defense would have had a field day.

The Press Conference Gambit

If you can’t testify in court, testify in front of cameras.

Trillanes announced he would hold a press conference on October 2 to “present all the matters that I would have presented and released during the impeachment trial.” He had teased “a lot of new heavy evidence” against Sara Duterte, inviting “the senator-judges and the people [to] decide whether these are significant.”

This is a narrative end-run around the judicial process. No cross-examination. No objections. No defense counsel poking holes in the provenance of his documents. Just Trillanes, a microphone, and whatever he chooses to reveal.

It is also potentially a violation of the Senate impeachment rules, which prohibit prosecutors, counsel, and witnesses from public comments on the merits of a pending trial. The court had already issued show-cause orders for possible violations of Rule 18 of the Senate Rules of Procedure on. Trillanes may have just walked out of the courtroom and directly into a contempt citation.

What the Prosecution Actually Loses

Here’s the uncomfortable question the prosecution must now confront: did they ever need Trillanes?

They have 1,800+ financial documents. They have AMLC records. They have bank subpoenas. They have Register of Deeds officials testifying on properties. They have the AMLC executive director himself scheduled to testify.

The institutional evidentiary chain—bank records → AMLC → Statements of Assets, Liabilities, and Net Worth (SALNs) → property records—is arguably stronger without Trillanes. It’s cleaner. It’s harder to dismiss as politically motivated. It doesn’t depend on the credibility of a witness the defense can paint as a vendetta-driven former coup plotter.

But it also lacks a narrator. Without Trillanes, the prosecution must weave a story from dry documents and institutional witnesses. They must establish not just that money moved, but that it was Sara Duterte’s money, that it was unlawfully acquired, and that it was concealed from her SALN.

That’s a high bar. And the “pressure” Trillanes referenced—whatever it was—suggests the prosecution knows it.

The ‘Pressure’ Nobody Will Name

Trillanes said he withdrew to relieve pressure on the prosecution. He did not say who was applying it. He did not say why. He did not say whether it was internal House politics, senator-judge preferences, defense threats, or something else entirely.

This is either noble self-sacrifice or a convenient exit from a witness stand he was never guaranteed to reach. Given that Escudero had already declined the subpoena and that the defense could have dismantled his testimony on hearsay and bias grounds, Trillanes’s withdrawal may have spared him a very bad day.

It also spared the prosecution the spectacle of its star witness being shredded on cross.

The Real Question

Forget Trillanes. The impeachment trial will proceed without him. The AMLC will testify. Bank officials will appear. Property records will be presented. The senator-judges will deliberate.

The question that matters now is whether the prosecution can transform financial data into constitutional accountability. Can they prove that specific assets belonged to Sara Duterte, that they were unlawfully acquired, and that their omission from her SALN constitutes an impeachable offense?

Or will this become the trial where the most talked-about witness never testified, the most explosive evidence was revealed at a press conference, and the Senate spent weeks listening to prosecutors who “fail” and witnesses who are “useless” while senators drift to the CR?

Trillanes may be gone from the witness list. But his shadow—and the “pressure” he wouldn’t name—will hang over this trial until the final vote.

And somewhere, a lawyer is still telling critics to get a life.
