House SecGen: We have not received advise on Rep. Duterte's whereabouts

Earlier this month, Rep. Duterte applied for a travel clearance from March 12 to April 15 to The Netherlands and Japan after the former President was arrested and brought to The Hague.

Duterte was arrested by local authorities on March 11 and brought to The Hague the same day. He made his first appearance before the ICC via videolink last March 14.

The ICC set an April 4 deadline for prosecutors to disclose to the defense evidence to be used for the confirmation hearing, while the defense was given an April 11 deadline to inform the prosecution what defense Duterte will raise. 

The confirmation of charges hearing is scheduled for September 23.
