The Islamabad High Court (IHC) on Monday rejected all three petitions filed by former president Pervez Musharraf against the special court constituted to try him for treason.
Musharraf had raised objections over the authority of the special court, appointment of judges and prosecutor in his petitions filed before high court.
The decision was announced by Justice Riaz Ahmad Khan, who declared the requests inadmissible.
The special court comprises Sindh High Court's Justice Faisal Arab, Justice Tahira Safdar of the Balochistan High Court and Justice Yawar Ali of the Lahore High Court.
Khalid Ranjha counsel for Pervez Musharraf, challenging the authority of the special court, stated that his client was the army chief when he introduced the 2007 emergency and only military court could examine his actions.
The two other petitions filed by Barrister Anwar Mansoor challenging the appointment of the judges for the special and Akram Sheikh as prosecutor in the treason case.
In these two petitions, Barrister Anwar Mansoor had taken the stance that the appointments were not legitimate.
Musharraf has been summoned by the special court on December 24 to face treason charges under Article 6 of the constitution. He has been accused of subverting, suspending and aborting the Constitution, imposing emergency in November 2007 and detained judges.
