Duterte impeachment trial enters critical phase on conviction vote threshold

MANILA – The impeachment trial of Vice President Sara Duterte advanced into a decisive phase Tuesday as the Senate Sitting as an Impeachment Court heard oral arguments on a fundamental procedural question that could determine the outcome of the case.

On its 29th day, the trial focused on the threshold needed for conviction, with both the prosecution and defense presenting competing interpretations of constitutional and procedural requirements. The central dispute concerns whether the two-thirds vote requirement for conviction should be calculated based on all 24 senators or only those present and voting at the time of the verdict.

The distinction carries significant weight. A conviction standard based on the full Senate membership would require 16 votes, while a calculation based only on present members could potentially lower that threshold depending on attendance.

Both camps have prepared comprehensive legal arguments on the issue, drawing on constitutional provisions, Senate rules, and precedent from previous impeachment proceedings. Legal experts have noted the outcome of this procedural battle may prove as consequential as the substantive charges against the Vice President.

The court is expected to issue a ruling on the voting threshold question before final deliberations on the impeachment charges commence.
