MANILA, Philippines — Political analysts are projecting a high probability that the House of Representatives will secure the necessary votes to impeach Vice President Sara Duterte, as the move to the plenary signals a solidifying “supermajority” stance against the OVP.
Following the House Committee on Justice’s determination that the complaints are sufficient in form and substance, experts suggest that the “numbers game” in the lower house is currently tipped heavily in favor of those seeking to transmit the articles of impeachment to the Senate.
Under the 1987 Constitution, only one-third (1/3) of all members of the House of Representatives is required to impeach a high-ranking official and send the case to the Senate for trial.
- Current House Composition: With approximately 300 members, the “pro-impeachment” camp needs only about 100 votes.
- The “Supermajority” Factor: Analysts point out that the alliance between Speaker Martin Romualdez and other major blocs has remained largely intact, while the “Duterte bloc” has seen its numbers dwindle as members shift toward the current administration’s banner.
“The threshold for impeachment in the House is intentionally low compared to the conviction threshold in the Senate,” noted a political science professor from the University of the Philippines. “Given the current political climate and the breakdown of the UniTeam alliance, securing 100 votes is not just likely—it’s almost certain if the leadership gives the green light.”
Analysts highlight three key factors driving the likelihood of a successful House vote:
- COA Findings: The Commission on Audit’s reports regarding the OVP’s confidential funds have provided “political cover” for lawmakers who might have otherwise been hesitant to move against a Duterte.
- Party Discipline: Major political parties, including Lakas-CMD and the Nacionalista Party, appear to be aligning with the move to “uphold accountability.”
- The 2028 Horizon: Strategic maneuvering for the next presidential election is seen as a subtext, with rivals seeking to weaken the Vice President’s political standing early.
While the House is expected to vote for impeachment, analysts warn that the Senate trial will be a significantly higher hurdle. Conviction requires a two-thirds (2/3) vote of all Senate members (16 out of 24 senators).
- The Senate historically acts as a “more independent” body.
- Some senators may be wary of the public backlash in pro-Duterte regions, particularly in Mindanao.
The impeachment complaint is expected to be included in the House Calendar of Business this week. If the House votes to impeach, it will mark the first time a Vice President has been formally impeached in Philippine history, setting the stage for a historic trial that will likely dominate the nation’s political landscape for the remainder of 2026.
