The Philippine Senate began the impeachment trial of Vice President Sara Duterte on Monday, July 6, 2026 [1].

The commencement of the trial marks a critical constitutional juncture for the Philippines, as the legislative body determines the fate of the country's second-highest official.

The proceedings in the Manila Senate chamber were met with procedural conflict. Senate President Sherwin Gatchalian attempted to move for the election of a presiding officer to lead the trial, but the motion was blocked by Senator Alan Peter Cayetano [1].

This disagreement led to a debate among the senators regarding the proper protocol for the trial's leadership. The impasse delayed the formal start of the evidentiary phase, as the chamber remained divided on how to establish the presiding authority for the proceedings [1].

Vice President Duterte was present for the first day of the trial on July 6, 2026 [1]. The Senate is tasked with acting as the high court of impeachment, a role that requires a clear administrative structure to ensure the legality of the eventual verdict.

Because the motion to elect a presiding officer was blocked, the first day concluded without the establishment of the trial's leadership framework [1].

The immediate procedural clash between Senator Cayetano and Senate President Gatchalian suggests that the impeachment trial may be characterized by significant political friction. By blocking the election of a presiding officer, the opposition or dissenting senators are challenging the administrative control of the trial, which could lead to further delays in the legal process against the Vice President.
