## Key takeaways

- Only Article II, which accuses Vice President Sara Duterte of unexplained wealth, is still before the Senate impeachment court after prosecutors withdrew three of four articles on Oct 13, 2026.
- A Sept 23 Senate ruling, passed 13-1, lowered the votes needed to convict from 16 to 14 by counting only senators able to take part.
- The Supreme Court has ordered the Senate court and the House to comment within five non-extendible days on a petition by Senators Robin Padilla and Bong Go and PDP-Laban officials against that rule; it has issued no restraining order.
- The trial resumes Nov 9 with the defense's evidence, and Senate President Sherwin Gatchalian said on Oct 27 it will likely run into December.
- Philippine market reports during the peso's record slide to 64.17 per dollar on Oct 27 cited oil, the balance of payments and US rates, not the trial.

The Sara Duterte impeachment trial is paused until Nov 9 and has narrowed to a single charge: alleged unexplained wealth. The 14-vote conviction rule now faces a Supreme Court challenge, the Daily Tribune reported on Oct 29.

Duterte has dismissed the case as a smear campaign. No verdict has been reached, and nothing in the record so far establishes guilt. This explainer sets out what remains, how the conviction threshold works, what the court challenge asks for, and what the timetable looks like.

## Sara Duterte impeachment trial status: one article left

The House of Representatives impeached Duterte for a second time in May 2026, after the Supreme Court voided the first set of articles in July 2025\. The Senate opened the trial in July, with Senator Francis "Chiz" Escudero elected presiding officer.

The House filed four articles. On Oct 13, the 39th trial day, lead prosecutor Rep. Gerville Luistro of Batangas withdrew three of them, according to GMA News live coverage of the session:

| Article     | Allegation (as filed by the House)                                                                                                                         | Status after Oct 13 |
| ----------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------- |
| Article I   | Alleged misuse of confidential funds                                                                                                                       | Withdrawn           |
| Article II  | Alleged unexplained wealth: incomplete disclosure in her statements of assets (SALN) and failure to divest business interests despite a constitutional ban | Still on trial      |
| Article III | Alleged bribery of Department of Education officials, 2022 to 2024                                                                                         | Withdrawn           |
| Article IV  | Alleged threats against President Ferdinand Marcos Jr., First Lady Liza Araneta Marcos and former Speaker Martin Romualdez                                 | Withdrawn           |

Escudero accepted the move from the chair, saying, as quoted by GMA News, "The court accepts and confirms the prosecution's manifestation." Senator-judges can still ask the court to reconsider. The House panel argued that Article II alone was enough to secure a conviction, according to the Daily Tribune.

The prosecution formally rested on Oct 15, the Philippine News Agency (PNA) reported. That leaves the defense to present its evidence on Article II when the court reconvenes.

### What the defense says

Defense lead counsel Sheila Sison said the withdrawal would not change how the defense presents its own case. She warned, however, that if the aim was to shorten the trial, the process would "bear unmistakable characteristics of a mistrial," because the defense would lose the chance to answer the dropped allegations with its own witnesses, GMA News reported.

Duterte said dropping the bribery article showed the prosecution lacked evidence, and she described the proceedings as a smear campaign that plays out daily, according to the same coverage. Prosecutors have said they may refer the bribery allegations to the Department of Justice and the Ombudsman instead.

## The vote math: why 14 votes instead of 16

The 1987 Constitution, Article XI, Section 3(6), says no person shall be convicted without the concurrence of two-thirds of "all the Members of the Senate." When the trial opened in July, the court read that as 16 of 24 senators, regardless of vacancies or absences.

On Sept 23, the court voted 13-1 to change the base. It now counts only senators who are legally and factually able to take part when judgment is rendered, the Daily Tribune reported. With four senators treated as unable to participate, the threshold fell to 14\. The figure can still change, depending on how many senator-judges are eligible at the final vote.

| Scenario                                           | Senators counted | Two-thirds requirement | Votes to convict |
| -------------------------------------------------- | ---------------- | ---------------------- | ---------------- |
| Original reading (July 2026)                       | 24 (full Senate) | 16.0                   | 16               |
| Revised rule, four unable to participate (Sept 23) | 20               | 13.3                   | 14               |
| Illustration: three unable to participate          | 21               | 14.0                   | 14               |
| Illustration: five unable to participate           | 19               | 12.7                   | 13               |

The last two rows are arithmetic illustrations of the revised rule, not reported scenarios. They show why the exact number of eligible senators at judgment matters: each change in that count can move the bar by a vote.

## The Supreme Court challenge

Senators Robin Padilla and Christopher "Bong" Go, together with officials of the PDP-Laban party, asked the Supreme Court to strike down the Sept 23 rule. They argue that two-thirds must be measured against the full 24-member Senate, as the constitutional text says "all the Members," according to the Daily Tribune.

The petitioners asked for a temporary restraining order, a status quo ante order and a writ of preliminary injunction. In an en banc resolution dated Oct 14, the court instead required the Senate impeachment court and the House to comment within five days of notice, a period it called non-extendible. It did so "without giving due course" to the petition, which means the justices have not yet decided whether to hear it on the merits or grant any interim relief.

As of the Oct 29 report, the court had issued no restraining order and no final ruling. Senate President Gatchalian has said the trial will continue under the revised rule unless the high court steps in.

## Timeline: Nov 9 resumption, likely into December

Speaking to reporters on Oct 27, Gatchalian said the trial would likely extend into December because the defense has yet to present its evidence and witnesses, PNA reported. He quoted the expectation in Filipino as "tatawid ito ng December."

Under a tentative arrangement, the Senate will put the trial first when sessions resume on Nov 9, then suspend it for about one to two weeks of plenary debate on the 2027 national budget, and return to the trial if the defense has not finished. Gatchalian dismissed reports that the defense needs only eight days, saying he had no information on such an arrangement and that the defense decides its own evidence. The budget fight itself is a separate pressure point; see our report on [watchdog warnings over the 2027 Philippine budget](https://bullquill.com/philippines-2027-budget-pork-senate-bicam/).

Senate Minority Leader Alan Peter Cayetano has argued against rushing. On Oct 13 he said the trial has no constitutional time limit, could end in January or February, and that the budget should come first, GMA News reported.

### Public opinion

A non-commissioned Social Weather Stations survey of 1,500 adults, conducted Sept 21 to 27, found 51% agreed that the Senate's decision, whether acquittal or conviction, should be accepted, GMA News reported on Oct 29\. Court spokesperson Regie Tongol said the court would keep its procedures fair and transparent.

### What conviction or acquittal would mean

Under Article XI, Section 3(7) of the Constitution, judgment in an impeachment case extends only to removal from office and disqualification from holding any office; criminal liability is a separate matter for the courts. Duterte has announced a bid for the presidency in 2028, so a conviction carrying disqualification would directly affect that race. An acquittal would end this case, and the Constitution bars a new impeachment against the same official within one year.

## What it means for ASEAN investors

The trial runs alongside a period of stress in Philippine markets, but the reports reviewed for this explainer do not link the two. The peso closed at a record 64.17 per dollar on Tuesday, Oct 27, based on Bankers Association of the Philippines data, GMA News and the Daily Tribune reported. Coverage of that slide pointed to higher oil prices, Middle East tensions, a widening balance of payments deficit and firm US rates. President Marcos attributed the drop to rising oil and fuel prices. None of those reports cited the impeachment trial as a driver.

For readers following the [Philippines](https://bullquill.com/tag/philippines/) and the [Philippine peso](https://bullquill.com/tag/philippine-peso/), the dated checkpoints are the congressional comments due to the Supreme Court, any interim order from the justices, the Nov 9 resumption, and the timing of the 2027 budget debate that will interrupt the trial. How markets respond to a verdict, if one comes in December, is not something the available data can show in advance.

## Frequently asked questions

### What is the status of the Sara Duterte impeachment trial?

The Senate trial is in recess and resumes on November 9, 2026, when the defense begins presenting evidence. Only Article II, on alleged unexplained wealth, remains after prosecutors withdrew the other three articles on October 13, 2026\. The prosecution rested on October 15.

In an en banc resolution dated October 14, 2026, the Supreme Court ordered the Senate impeachment court and the House to comment within five non-extendible days on a petition by Senators Robin Padilla and Bong Go and PDP-Laban officials.

### When will the Sara Duterte impeachment trial end?

No end date is set. Senate President Sherwin Gatchalian said on October 27, 2026 that the trial will likely extend into December, with a one- to two-week pause for 2027 budget debates.
