Khan was acting on a petition filed by advocate Mohammad Aslam Ghuman seeking action against Musharraf for ordering the confinement of the Supreme Court judges.

The FIR states that Musharraf and others had detained the Supreme Court judges and their families at their houses and their children were neither allowed to attend school nor permitted to appear in examinations.

Judge Khan's order came 11 days after the Supreme Court July 31 held that Musharraf had acted extra-judicially, illegally and unconstitutionally in declaring an emergency and sacking the apex court judges.

A 14-member bench headed by Chief Justice Iftikhar Muhammed Chaudhry, however, stopped short of censuring Musharraf as had been demanded in a petition the court was hearing against the declaration of the emergency.

The Supreme Court had summoned Musharraf, who is currently in London on a lecture tour, to appear before it July 29 in person or through his lawyer but he failed do so.

'Determining responsibility for the steps taken on Nov 3, 2007 is necessary,' Chaudhry observed July 22 before issuing summons.

Chaudhry, who was one of the 80-odd Supreme Court and high court judges sacked, had been reinstated in March after a bruising lawyers' agitation.

Musharraf had sacked the higher judiciary after it refused to take fresh oath under the Provisional Constitutional Order (PCO) he promulgated along with the emergency.

The emergency had been declared just as the Supreme Court was to deliver its verdict on the constitutionality of Musharraf's re-election in October 2007.

It had been contended that the same parliament and provincial assemblies that had elected Musharraf in 2002 had re-elected him in 2007 and this was unconstitutional.
