The Senate impeachment court indicates it can require Office of the Vice President (OVP) chief of staff and Undersecretary Zuleika Lopez to explain her non-appearance if she fails to comply with a subpoena to testify as a witness in Vice President Sara Duterte’s impeachment trial. Impeachment court spokesperson Atty. Regie Tongol says that, as with other compulsory legal processes, non-compliance with a court-issued subpoena can lead to an order requiring the concerned party to justify why they should not be held in contempt. The spokesperson’s remarks were reported during a press briefing, emphasizing that the next step would be an explanation request in response to failure to appear and testify. Both reports frame the issue as procedural: whether Lopez will be compelled to account for her absence if she does not attend the scheduled proceedings. The sources do not provide details on the subpoena’s timing, the specific questions expected in her testimony, or any statement from Lopez regarding compliance.
