Former President Rodrigo Duterte will have to face a local court in the Netherlands before he will be brought to the International Criminal Court, Palace Press Officer Undersecretary Atty. Claire Castro said on Wednesday. 

Castro said this is to determine if the process of his arrest in the Philippines was proper.

''Sa aking pagkakaalam, dadalhin muna siya sa isang local court at doon titingnan, aalamin kung tama ba 'yung proseso ng pag-arrest at kapag po na-validate, na sinabi naman na tama ang pagkakadala sa kanya sa bansang kung saan siya dadalhin, dadalhin na po siya sa The Hague, sa ICC,'' Castro said at a press briefing.

(From what I know, he will be brought to a local court to determine if the process of his arrest was proper and if it's already validated that it was correct, he will be brought to The Hague, to the ICC.)

She said if found guilty of crimes against humanity, it will depend on the ICC if the former chief executive will face 30 years of imprisonment or life imprisonment.

President Ferdinand "Bongbong" Marcos Jr. said Interpol Manila received an official copy of the ICC warrant hours before Duterte's arrival from Hong Kong on Tuesday. 

The President said the arrest was done "because Interpol asked us to do it and we have commitments." He also insisted that the arrest was proper and correct, wherein "every single necessary procedure" was followed.

The plane carrying Duterte arrived in Dubai at around 8:03 a.m. Wednesday (Manila time) for a layover. It left the Philippines on Tuesday at 11:03 p.m. Tuesday.
