KARACHI: Disposing of a petition filed by Saulat Mirza's sister challenging his death warrant, the Sindh High Court (SHC) on Friday advised her to approach the Supreme Court.

Earlier this week, an anti-terrorism court (ATC) in Karachi had issued Mirza's death warrant after the moratorium on the death penalty was lifted completely.

Preparations for the execution of Saulat Mirza are underway in Balochistan's Machh Central Jail.

Mirza's sister Samira Wajahat petitioned that an appeal against her brother's conviction was pending in the apex court and hence the implementation of his death sentence should be suspended until the SC decided on the appeal.

Disposing of the petition, the court advised Samira Wajahat to approach the Supreme Court with her application, as that is where her earlier appeal was submitted.

Mirza was sentenced to death by the ATC in May 1999 for murdering the managing director of then-named Karachi Electric Supply Corporation Shahid Hamid, his driver Ashraf Brohi and guard Khan Akbar in July 1997. He was moved along with four high-profile prisoners to the Machh jail, Balochistan, in April 2014.
