Philippine senators have set themselves as an impeachment court for the trial of Vice President Sara Duterte over corruption and other criminal allegations but they voted to send the raft of complaints back to the House of Representatives due to legal questions.

Philippine senators were sworn in as jurors on Tuesday in the impeachment trial of Vice President Sara Duterte, who faces a lifetime political ban if convicted of high crimes and betraying the public trust.

A lawmaker has asked the Senate as to what would be the basis of Vice President Sara Duterte’s response to its summons, when the articles of impeachment were sent back to the House of Representatives.
