An impeachment proceeding against Philippine Vice President Sara Duterte can't proceed due to a constitutional limit on the annual number of impeachments.

The Philippines' top court blocked the impending Senate impeachment trial of Vice President Sara Duterte on Friday, saying it violated a constitutional provision against multiple impeachment proceedings within a single year.

The Philippine Supreme Court has blocked an impeachment trial against Sara Duterte, marking a victory for the country's vice president. The lower house of the Philippine parliament had voted to impeach Duterte in February after she was accused of misusing public funds and threatening to kill President Ferdinand "Bongbong" Marcos Jr.
