The impeachment trial of Philippine Vice President Sara Duterte commenced on Monday, July 6, with her political future and 2028 presidential ambitions hanging in the balance. The proceedings are anticipated to last for several months and will determine if Duterte is removed from office and barred from seeking future government posts. The trial is poised to be a significant event for Philippine politics, particularly in shaping the landscape for the next presidential election.

The case against Duterte focuses on four main allegations: alleged misuse of confidential funds, amassing unexplained wealth, bribing government officials, and threatening the lives of President Ferdinand Marcos Jr., First Lady Liza Araneta Marcos, and former House Speaker Martin Romualdez. The prosecution will dedicate 11 hearing days to the alleged kill threat, 31 days to the confidential funds issue, eight days to bribery, and 12 days to unexplained wealth. Duterte has denied any wrongdoing, asserting that the impeachment is politically motivated.

The trial structure involves a rigid 92-day calendar, with the prosecution allocated 62 days to present evidence and the defense 30 days. Proceedings are scheduled from Monday to Wednesday at 2:00 p.m. until July 27, then shifting to Tuesday to Thursday at 3:00 p.m. A conviction requires at least 16 votes from the 24-member Senate, a threshold that has sparked debate due to the current composition and potential absences within the Senate. Some legal experts suggest the conviction threshold could dynamically adjust to 14 or 12 votes, though the presiding officer, Senate President Sherwin Gatchalian, maintains it remains at 16. If convicted, Duterte would become the first Philippine Vice President to be removed from office through impeachment.
