The deliberation process on whether to impeach the vice-president has been thrown back to the Lower House for consideration.

Philippine senators on Tuesday voted to send an impeachment case against Vice President Sara Duterte back to the lower house for clarification, just hours after convening a trial that could see her banned from politics for life.

The planned trial of Philippine Vice President Sara Duterte is in doubt after the articles of impeachment were unexpectedly sent by senators back to the House of Representatives, whose prosecutors said they can’t — for now — comply with the request.
