The decision could grant Duterte a stay of execution as a likely contender for the next president. The trial could result in a lifetime ban from politics

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.

After a series of debates among members that included a motion presented by a Duterte ally to dismiss the case, the Senators voted in favour of returning it to the lower house to certify that the complaint was constitutional. The lower house in February voted to impeach the vice president for alleged high crimes and betrayal of the public trust, allegations she has vehemently denied.

A majority of the senators on Tuesday approved a motion to return the case to confirm the complaint did not violate the constitution and the next session of Congress was “willing and ready” to pursue the impeachment complaint following midterm elections in May.

The decision could be a stay of execution for Duterte, a likely contender to be the next president, in a trial that could be a pivotal moment in Philippine politics.
