THE Supreme Court’s unanimous ruling halting the impeachment complaint against Vice President Sara Duterte may spark a political crisis, veteran election lawyer Romulo Macalintal said.

Philippine Vice President Sara Duterte scored a big legal win on Friday when the Supreme Court struck down an impeachment complaint against her, ruling that it was unconstitutional.

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.
