The Philippine Senate is starting the impeachment trial of Vice President Sara Duterte in a politically volatile event that will unfold with the backdrop of her bitter feud with President Ferdinand Marcos Jr. The proceedings could eventually lead to a trial in the Philippine Senate.
The complaints center on the Office of the Vice President’s (OVP) expenditure of 125 million pesos in confidential funds in 2022.
Vice President Duterte has denied any wrongdoing, characterizing the impeachment efforts as a political attack. The rift between the Vice President and the President has escalated publicly.
Why is Vice President Sara Duterte facing impeachment?
The primary driver of the impeachment complaints is the controversy surrounding “confidential and intelligence funds” (CIF).

The Commission on Audit found that the OVP spent 125 million pesos of these funds within a very short window in late 2022.
Critics in the House of Representatives argue that the expenditure constitutes a betrayal of public trust and a violation of the Constitution. The complaints allege that the Vice President bypassed standard procurement and auditing protocols, effectively spending public money without legislative approval.
What is the legal process for impeachment in the Philippines?
The impeachment process in the Philippines is a two-stage procedure divided between the two chambers of Congress. The House of Representatives acts as the prosecutor, while the Senate serves as the impartial court.

First, a verified complaint must be filed with the House. The House Committee on Justice then determines if the complaint is sufficient in form and substance. If the committee finds the charges valid, it drafts the “Articles of Impeachment.” A vote of one-third of all members of the House is required to send the articles to the Senate.
Once the House transmits the articles, the Philippine Senate convenes as an Impeachment Court. Senators take an oath or affirmation to perform their duties without fear or favor. The trial involves the presentation of evidence and the cross-examination of witnesses by both the House prosecutors and the Vice President’s legal defense team.
To convict a high-ranking official, the Constitution requires a two-thirds vote of all members of the Senate. If convicted, the official is removed from office and may be disqualified from holding any other public office in the Philippines.
How does the Marcos-Duterte rift influence the proceedings?
The legal battle is unfolding against a backdrop of extreme political volatility. In 2022, Ferdinand Marcos Jr. and Sara Duterte ran on a joint ticket known as “UniTeam,” uniting the powerful political dynasties of the north and south. This alliance was intended to ensure a landslide victory and a stable governing coalition.
However, the alliance fractured over policy disagreements and perceived slights. By 2024, the relationship had deteriorated into a public feud. Vice President Duterte has criticized the administration’s handling of the economy and its alignment with the United States, while members of the Marcos camp have questioned the Vice President’s transparency regarding government spending.
Political analysts observe that the timing of the impeachment complaints coincides with the lead-up to the 2025 midterm elections. The outcome of the proceedings could significantly shift the balance of power in Congress and influence the trajectory of the 2028 presidential race, where both factions are expected to seek dominance.
What are the potential consequences of a Senate trial?
A Senate trial would be a high-profile event with significant implications for Philippine governance. If the Vice President is removed, the line of succession would be altered, and the political vacuum could lead to further instability within the executive branch.
Even if the Vice President is acquitted, the trial would likely expose sensitive details regarding the use of intelligence funds across various government agencies.
Furthermore, the trial would test the independence of the Senate. Because many senators were elected with the support of either the Marcos or Duterte families, the voting pattern would reveal the current state of loyalty and power dynamics within the upper house.
The next confirmed checkpoint in this process is the House Committee on Justice’s determination on the sufficiency of the filed complaints. Official updates regarding the schedule of hearings are typically posted on the House of Representatives’ official portal.
