Core Event: Senate Impeachment Trial Begins
On Monday, July 6, 2026, the Philippine Senate opened the impeachment trial of Vice President Sara Duterte. The House charged her with misuse of public funds, amassed wealth, and threats against President Ferdinand Marcos Jr., his spouse and a former House speaker. Conviction requires a two-thirds majority—at least 16 of the 24 senators.
Background: Collapse of the Marcos-Duterte Alliance
The trial follows the collapse of the 2022 Marcos-Duterte joint ticket after former President Rodrigo Duterte’s arrest and transfer to the ICC in March 2025. Senate infighting—Senator Ronald “Bato” dela Rosa’s vote for Alan Peter Cayetano as Senate president in May, his disappearance, and the later election of Senator Sherwin Gatchalian as Senate president—has deepened the split.
Key Actors
Key actors: Vice President Sara Duterte; President Ferdinand Marcos Jr.; President Rodrigo Duterte (detained in The Hague); Senator Ronald “Bato” dela Rosa (missing); Senate presidents Alan Peter Cayetano and Sherwin Gatchalian; professor Ederson Tapia (University of Makati); Congressman Robert “Ace” Barbers; lawyer Michael Poa; professor Jean Encinas-Franco (University of the Philippines).
Data & Stakes
A conviction needs 16 of the 24 senators. The 2012 impeachment of a chief justice lasted four months. Opinion polls list Sara Duterte as a leading contender for the 2028 presidential race, making the trial pivotal for both camps.
Official Statements & Responses
Congressman Barbers said the evidence will decide the case. Duterte’s defense, led by Michael Poa, called the charges baseless and described the impeachment as constitutionally infirm, procedurally defective and substantively deficient. Ederson Tapia warned the trial’s legitimacy will depend on perceived fairness, not partisan maneuvering.
Criticism & Opposition
Legal scholars caution that a perceived partisan process could erode public trust. Jean Encinas-Franco cited the 2001 Estrada impeachment, where evidence suppression sparked protests, urging equal time for both sides. Critics also argue the trial may be used to sideline Duterte’s presidential bid.
Conflicting Reports & Gaps
Sources differ on whether Vice President Duterte will attend the opening session; the summons permits representation by counsel. Senator dela Rosa’s whereabouts remain unknown. The trial’s length is uncertain, with procedural disputes and witness scheduling likely to affect its pace.
Verbatim Quotes
- “If it is seen as politically motivated or lacking credibility, questions may linger regardless of the outcome,” — Ederson Tapia, University of Makati
- “We will let the evidence speak for itself.” — Robert “Ace” Barbers, Congressman, prosecution spokesperson
- “Duterte's lawyer, Michael Poa, said the defence was prepared to prove the allegations were "baseless".” — Michael Poa, lawyer for Sara Duterte
- “They really have to make sure that both the prosecution and the defence are given enough time and voice … so the public does not perceive the trial as favouring one side,” — Jean Encinas-Franco, University of the Philippines
What’s Next
The Senate will hear arguments in the coming weeks. The verdict is expected to shape the 2028 presidential field and decide whether the Marcos or Duterte camp will dominate Philippine politics.
