MANILA, Philippines — Formally drawing her battle lines ahead of a high-stakes legislative showdown, the country’s second-highest official has launched a direct legal counter-offensive against her detractors. Vice President Sara Duterte has requested the Senate impeachment court to completely dismiss the articles of impeachment filed against her.
Her defense team, led by spokesperson Michael Poa, arrived at the Office of the Senate Secretary late Monday afternoon, June 1, carrying five suitcases packed with documentation to beat the non-extendible 7:00 PM submission deadline.
In her main 50-page formal response, the Vice President characterized the charges as “constitutionally infirm, procedurally defective, and substantively deficient.” The core of the defense strategy centers on a blistering critique of how the House Committee on Justice handled the initial evaluation process:

The submission was filed “without prejudice” to a separate, pending petition filed by Duterte’s camp before the Supreme Court challenging the legality of the lower chamber’s actions.
The House panel of prosecutors immediately pushed back against the Vice President’s prayer for an early dismissal. Lead prosecutor and House Committee on Justice Chair Gerville “Jepoy” Luistro (Batangas) vowed to heavily contest any motion to throw out the case before arguments are heard:

The legal showdown marks the culmination of a massive political rift that has completely reshaped the national executive landscape since the start of the year.
| Impeachment Milestone Track | Core Political & Legal Data | Operational Timeline Matrix |
| The Initiation Spark | Two separate complaints filed by the Makabayan bloc and progressive coalitions on February 2, 2026, alleging betrayal of public trust, graft, and culpable violation of the Constitution. | Reached formal committee referral on Feb 23, officially locking in the one-year ban on concurrent filings. |
| The House Plenary Vote | House Resolution No. 989 was aggressively adopted in a sweeping 257–25 vote, immediately transferring the case to the upper chamber. | Executed on May 11, 2026, marking only the second time a sitting VP has been successfully impeached. |
| The Senate Trial Framework | Senators formally took their oaths as senator-judges under Senate President Alan Peter Cayetano. | The Senate convened as an court on May 18; the trial proper is scheduled to begin on July 6, 2026. |
Spokesperson Michael Poa announced that Duterte’s camp will impose a strict self-declared media blackout regarding the specific merits of the case moving forward, citing the legislature’s sub judice rules. However, the defense confirmed that the Vice President is fully prepared to take the witness stand and testify personally “if necessary” once the trial proper begins in July.
With the prosecution given a non-extendible five-day window to file its formal reply to her answer, the upcoming trial is poised to serve as a massive, defining stress test for the country’s constitutional checks and balances.
