Vice President Sara Duterte's historic impeachment trial begins July 6, with both prosecution and defense teams declaring readiness. She faces four articles including graft, constitutional violations, and threats against top officials.

The Philippines is about to witness something it has never seen before: the impeachment trial of a sitting vice president. Vice President Sara Duterte will stand before the Senate on Monday, July 6, at 2 p.m., facing four articles of impeachment that carry the weight of potential permanent removal from office and a lifetime ban from public service.

Duterte is accused of misusing P612.5 million in confidential funds during her time as vice president and education secretary. The charges extend further: amassing billions of pesos in wealth that cannot be explained, bribing Department of Education personnel, and making public threats against President Ferdinand Marcos Jr., first lady Liza Araneta-Marcos, and former speaker Martin Romualdez. The four articles themselves are sweeping—betrayal of public trust, culpable violation of the Constitution, graft and corruption, and other high crimes. If convicted on any count, she will be stripped of her office and permanently disqualified from holding any government position again.

Both the prosecution and defense have spent weeks preparing for this moment, and both say they are ready. Robert Ace Barbers, spokesman for the prosecution, told reporters that his team has been building its case since the House Committee on Justice began its clarificatory hearings months ago. The prosecution has identified its first witnesses for the opening week: National Bureau of Investigation Regional Director Jeremy Lotoc, senior agent John Mark Calilung, and House Office of Sergeant-at-Arms Legislative Security Bureau Executive Director Belinda Bello. These witnesses will address the article alleging that Duterte threatened to hire an assassin to kill the president, first lady, and former speaker if she herself were killed. Among the prosecution's listed witnesses is someone identified as "Mary Grace Piattos," believed to be a fictitious name, allegedly a recipient of misappropriated Department of Education confidential funds.

The defense team, led by lawyer Shiela Sison and represented publicly by spokesman Michael Wesley Poa, has signaled it is prepared for a trial that could stretch seven to eight months or longer. Poa said the defense has completed its legal preparations and is focused now on procedural compliance—determining who will appear on the opening day and who will lead arguments. The defense has indicated it will present witnesses of its own and plans to argue that the allegations against Duterte lack factual basis. Poa himself has said he is willing to testify if called by the prosecution, provided the questioning does not breach attorney-client privilege or venture into matters unrelated to his former role as Undersecretary and Chief of Staff of the Department of Education.

A central point of contention is a sealed box of tax records from the Bureau of Internal Revenue containing financial information about Duterte and her husband. The prosecution has pushed hard for the box to be opened during open court proceedings, calling it key evidence in the unexplained wealth article. The defense has not objected to opening it but has raised concerns about protecting the privacy rights of individuals whose information may be in the documents and about preserving its objections to how the prosecution obtained the materials. Senator Panfilo Lacson has argued that the Senate should return the box to the House prosecution panel, saying the impeachment court has no legal authority to keep or unseal evidence before it is formally presented at trial.

Duterte herself has not yet decided whether she will appear in person. Her legal team has indicated that her physical attendance will depend on how the trial unfolds and on their strategic advice, which they are keeping confidential. Malacañang has publicly urged her to show up, with Palace Press Officer Claire Castro arguing that personal appearance would allow Duterte to demonstrate her innocence and face her accusers directly. Duterte remains in regular contact with her legal team and is described as being in good spirits, regularly briefed on strategy, and continuing to focus on her official duties.

The trial will run from July 6 through July 22 on Mondays, Tuesdays, and Wednesdays at 2 p.m. After the State of the Nation Address, the schedule shifts to Tuesdays and Thursdays at the same time. Senate President Sherwin Gatchalian will preside, with the other senators sitting as judges. The prosecution has proposed making the proceedings more accessible to Filipinos by using both English and Filipino and hiring regional interpreters, arguing that taxpayers have a right to understand what is happening in their name. Barbers has framed the trial not as a personal attack on Duterte but as a test of whether the Constitution's accountability mechanisms actually work. The trial is expected to last at least 90 days, making it one of the longest and most consequential legal proceedings in recent Philippine history.

We have been preparing since the House Committee on Justice's clarificatory hearings began, because the preparations for those hearings covered the same issues that are now being taken up
— Robert Ace Barbers, prosecution spokesman
Although all of us want this to be over so we can finally present our case and move on from this impeachment issue, we will do our best to defend our client and protect her rights. Even if the trial lasts seven to eight months—or even longer—the defense is definitely ready
— Michael Wesley Poa, defense spokesman

What does it mean that this is the first impeachment trial of a sitting vice president? Has this never happened before?

Model

Never. The Philippines has had impeachment trials, but always of former officials or those no longer in office. This is different—Duterte is still serving as vice president while being tried for her actions in that very role. It's unprecedented constitutional territory.

Inventor

The charges seem to span a lot of ground—money, threats, corruption. Is there one that's considered the strongest?

Model

The prosecution spokesman wouldn't say which is strongest, but the threats article seems to have the most dramatic hook. Duterte allegedly said she hired an assassin to kill the president, first lady, and former speaker if she were killed. That's the one they're leading with in the first week.

Inventor

What's the significance of that sealed BIR box everyone keeps talking about?

Model

It contains tax records that could prove or disprove the unexplained wealth charge. The prosecution wants it opened in open court so the public sees the evidence. The defense isn't refusing to open it, but they're protecting themselves—making sure opening it doesn't waive their right to challenge how the prosecution got it in the first place.

Inventor

Will Duterte actually show up to her own trial?

Model

That's unclear. Her lawyers are keeping it as a strategic decision. The Palace is publicly pushing her to appear, saying it would demonstrate her innocence. But her team is weighing whether her presence helps or hurts their case.

Inventor

How long is this going to take?

Model

At least 90 days, possibly seven to eight months or longer. The defense is explicitly prepared for a marathon. The prosecution hasn't ruled out a quick resolution, but nobody's expecting this to be over in weeks.

Inventor

What happens if she's convicted?

Model

She's removed from office immediately and permanently barred from holding any government position ever again. It's not just losing her job—it's a lifetime exile from public service.
