There are now strong indications that the hearing may take place inside Adiala Jail.
The trials will be conducted by the Special Anti-Terrorism Court (ATC) presided over by Judge Amjad Ali Shah.
According to official orders, former foreign minister Shah Mehmood Qureshi, currently imprisoned at Kot Lakhpat Jail in Lahore, will be produced before the court at Adiala Jail today.
Meanwhile, the court has issued arrest warrants for Sub-Inspector Riaz, the investigating officer in the GHQ attack case and Magistrate Mujtaba Al-Hasan, a key witness who conducted the identification parade.
Both had repeatedly failed to appear before the court over the past three months despite summons.
The magistrate has been summoned via the High Court, while the arrest warrant for the investigating officer was issued through the City Police Officer (CPO).
In the remaining 12 cases, charge sheets will be formally filed, and copies of challans will be distributed among the accused.
