Vice President Sara Duterte slammed the International Criminal Court (ICC)'s prosecution team's denial of her father, former President Rodrigo Duterte's interim release request, questioning the purpose of an interim release provision if such would be denied.

In a media interview on Wednesday, Duterte questioned the ICC's Office of the Prosecutor's 'strong opposition' of the former president and his lawyers' request for interim release to an undisclosed country made on the grounds of the former president's old age and health.

"As a lawyer, why did you put a provision of interim release in your law if you weren't going to give it to the accused? Especially to someone who's already 80 years old and in need of an assistant and caregiver... that's a huge question," Duterte said.

The Vice President said that her father's detention was an 'injustice', for other countries allow the accused the right to bail yet the ICC does not.

“And now you have an interim release but you don’t give it, so it seems like they are for human rights but they don’t provide it,” Duterte added.

Duterte denied that her father was a threat to the witnesses of his alleged crimes against humanity in relation to his administration's bloody war on drugs, arguing that he never prosecuted them while he was still in the Philippines, and also questioned the prosecution's basis of using her influence as vice president for denying her father's request for interim release.

She even went on to say that the ICC using her family's statements against the court as one of the reasons for denying her father's interim request was 'very wrong'.

“It is very wrong that they would use the family’s statements as a reason to oppose an accused’s petition,” Duterte added.

Despite this, Duterte admitted that she has not yet the prosecution's opposition in full, and that it was the prosecution's job to oppose the defense's proposal.

Former President Duterte has been detained in The Hague, Netherlands after he was handed over to the ICC on March 12 following his arrest in the Philippines due to alleged crimes against humanity. Velle White/DMS
