In his remarks, Justice Mazhar Alam inquired from the state counsel whether government was unaware about the special court orders in the case. In reply, counsel Sheikh Akram said government had cognizance of the court orders.
The court also summoned Interior Secretary Arif Khan and directed him to file an explanation over Musharraf’s departure within 15 days.
Musharraf, who faces charges of treason and murder, left the country on March 18 and arrived in Dubai for urgent medical treatment after a three-year travel ban was lifted.
Lawyers for the former president have said he needs urgent medical treatment not available in Pakistan.
“I am going abroad for treatment but will return to face the cases against me,” a party spokesman in Karachi had quoted him as saying. “I am a commando. I love my motherland.”
Musharraf was banned from leaving Pakistan in March 2013 after he returned to the country on an ill-fated mission to contest elections.
The former ruler was barred from taking part in the elections and instead faces a barrage of legal cases.
