Prosecutors dropped three of four impeachment charges against Vice President Sara Duterte on October 13, leaving only the allegation that she hid unexplained wealth. The Senate, sitting as an impeachment court, had already lowered the votes needed to convict from 16 to 14.
Duterte's lawyers opened their defense on November 9. Davao City assessor Jaime Adalin and city accountant Vingelin Bajan testified, and senator-judges pressed both when they said they could not recall details or signatures. Lead prosecutor Gerville Luistro told Reuters the prosecution is "all in" on the wealth charge and wants the trial finished in 2026.
Why it matters
A conviction ends the Duterte dynasty's path back to the presidency in a US treaty ally hosting nine American military sites.

Scenarios
1
Senate acquits Duterte, 2028 path stays open
Likely
Resolves by End of 2026
Discussed by: South China Morning Post, Asia News Network, Philippine Daily Inquirer columnists
Cayetano's bloc holds enough senators in the no column. The prosecution fails to reach 14 votes. Duterte is acquitted on the remaining unexplained-wealth article and walks out as the front-runner for 2028. Polls already show her lead has narrowed, so an acquittal becomes both a legal and political reset.
2
Senate convicts, Duterte barred from office
Unlikely
Resolves by End of 2026
Discussed by: Reuters, Al Jazeera, Washington Post analyses
Senators aligned with Marcos reach the 14 votes needed on the remaining article. Duterte is removed and disqualified for life. Her 2028 bid ends. The Duterte family loses its main national platform while Rodrigo Duterte remains in ICC custody at The Hague.
3
Supreme Court halts the trial on procedural grounds
Deadline passed (Q3 2026)
Discussed by: Rappler legal columnists, Philippine constitutional law scholars
Duterte's lawyers ask the Supreme Court to enjoin the trial, citing the same one-year bar or other procedural defects that killed the first case. The court issues a temporary restraining order, freezing proceedings before a vote.
4
Senate drops the case without a vote
Possible
Resolves by End of 2026
Discussed by: Philippine Star, Inquirer political reporters
The trial bogs down on motions and pre-trial fights. Cayetano's bloc votes to dismiss for failure of the prosecution to make a case, or for lack of jurisdiction, ending the trial before a verdict on the articles. Echoes the 2001 Estrada walkout that ended his trial.
5
Supreme Court restores the 16-vote threshold before a verdict
Possible
Resolves by End of 2026
Discussed by: Defense spokesman Michael Poa; Philippine constitutional law scholars cited by Philstar and the Inquirer
Duterte's lawyers ask the Supreme Court to rule that the Constitution's two-thirds requirement means 16 of all 24 senators, not 14 of those able to sit. Poa said the petition would come 'sooner rather than later.' A favorable ruling would raise the number of votes prosecutors need before the court votes on the remaining article.
Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
1 of 3
November 2000 - January 2001
Joseph Estrada impeachment (2000-2001)
The House impeached President Joseph Estrada on charges of taking bribes from illegal gambling and stashing money under a fake name. The Senate trial collapsed on January 16, 2001, when 11 pro-Estrada senators voted to keep a sealed envelope of bank records out of evidence.
Then
The prosecution panel walked out. Days later, the EDSA II protests pushed Estrada from office and Vice President Gloria Macapagal Arroyo was sworn in.
Now
Estrada was later convicted of plunder in 2007 and pardoned by Arroyo. The case set the modern template for impeachment fights in Manila, including the chamber-counting and procedural votes now shaping the Duterte trial.
Why this matters now
Estrada shows how a Philippine impeachment can end without a verdict on the merits. Cayetano's bloc could replicate the 2001 procedural exit and spare Duterte a vote on the articles.
2 of 3
December 2011 - May 2012
Renato Corona impeachment (2011-2012)
The House impeached Supreme Court Chief Justice Renato Corona on charges of hiding millions of dollars in undeclared assets. The Senate trial ran for five months and produced televised testimony about his dollar accounts and properties.
Then
On May 29, 2012, the Senate convicted Corona 20-3 on the unexplained-wealth article. He was removed and barred from public office.
Now
Corona is the only Philippine official ever convicted in a Senate impeachment trial. The case showed that hidden-wealth charges, with documentary proof, can clear the two-thirds bar.
Why this matters now
Corona is the prosecution's blueprint. The second article against Duterte targets unexplained wealth in her SALN filings, the same legal theory that beat Corona.
3 of 3
December 2016 - March 2017
Park Geun-hye impeachment (2016-2017)
South Korea's National Assembly impeached President Park Geun-hye over a corruption and influence-peddling scandal involving her confidante Choi Soon-sil. The Constitutional Court upheld the impeachment unanimously on March 10, 2017.
Then
Park was removed from office and arrested weeks later. A new election brought Moon Jae-in to power.
Now
Park was convicted of bribery and abuse of power, sentenced to more than 20 years, and pardoned in 2021. The case redrew the South Korean political map and ended her party's grip on the presidency.
Why this matters now
Park shows how an East Asian democracy can use impeachment to remove a dynastic political figure mid-term and reshape the next election cycle. The 2028 stakes for Duterte mirror that dynamic.
