The former president faces treason charges under Article 6 for suspending, subverting and abrogating the Constitution, imposing an emergency in the country and detaining judges of the superior courts.
Musharraf had taken ill and was rushed to the AFIC on January 2 when he was being transported under heavy guard to the special court. He has since been admitted in the hospital.
His trial is taking place at the National Library here which is the heavily secured ‘Red Zone' here that houses all important institutions like the Prime Minister's House, Supreme Court and the Diplomatic Enclave.
Prior to Musharraf's arrival, the Bomb Disposal Squad had carried out a thorough check inside the court premises and jammers were installed.
Earlier in the day, the special court had reserved its verdict for conducting his treason trial under the Army Act.
The court had summoned him today warning that a non-bailable arrest warrant would be issued if he fails to turn up.
