The impeachment process against Vice President Sara Duterte began with four complaints filed by different groups on December 2, 4, and 19, 2024. A fourth complaint was filed by a resolution approved by more than one-third of House members on February 5, 2025, which was transmitted as the Articles of Impeachment to the Senate on the same day, according to Inquirer.net.

Supreme Court rules on impeachment complaints

The Supreme Court ruled that the first three complaints—filed by citizens under Article XI, Section 3(2),were different from the fourth complaint, which was filed under Section 3(4) via a verified resolution signed by at least one-third of House members. The court ruled that the first three complaints were “archived and therefore deemed terminated or dismissed” on February 5, 2025, meaning no new complaint can be initiated until after February 6, 2026.

It also reminded the House of Representatives that such complaints must be included in the Order of Business within 10 session days from endorsement, and that the Constitution does not grant discretion to the House Speaker or Secretary General to delay this. The Supreme Court emphasized that the one-year ban is counted from the time an impeachment complaint is dismissed or otherwise rendered no longer viable.

Impeachment support and evidence

According to GMA Network. At least 215 House members support the impeachment of Vice President Sara Duterte. Rep. Jude Acidre and Rep. Terry Ridon announced this a day after the Articles of Impeachment were calendared under the House’s Order of Business and its copies were distributed to House members.

Acidre noted that some House members who were initially skeptical were eventually convinced after the clarificatory hearings revealed billions of pesos that were not declared in Duterte’s Statements of Assets, Liabilities, and Net Worth (SALNs), among other revelations. “A lot of people were convinced because of the evidence,” Acidre said.

Ridon agreed with Acidre, noting that more than two-thirds of the House members are in favor of the impeachment of the Vice President at this point. He was referring to the impeachment complaint lodged against Duterte in 2025, which did not undergo committee deliberations because the constitutional requirement of at least one-third of all House members voting in favor of impeachment was already met.

Procedural guidelines and next steps

The Supreme Court outlined guidelines to ensure fairness in impeachment proceedings. These include including the Articles of Impeachment and supporting evidence when shared with House members for endorsement, ensuring the evidence is sufficient to support the charges, and making the Articles and evidence available to all members of the House of Representatives.

These guidelines aim to prevent any procedural irregularities and ensure that the impeachment process is conducted in accordance with the Constitution and the rules set by the Supreme Court.
