The issue could snowball into a conviction disqualifying him from standing for election, GeoTV quoted legal experts as saying.

The bench comprising Justice Mohsin Akhtar Kayani, Justice Babar Sattar and Justice Miangul Hassan Aurangzeb summoned Khan in personal capacity on August 31.

It forwarded the case to the Chief Justice of Pakistan, seeking inclusion of more judges and enlarging the bench.

The Pakistan Tehreek-e-Insaf chairman had staged a rally in the federal capital on August 20 to express solidarity with his chief of staff Shahbaz Gill after claims of torture in custody.

He warned the Islamabad inspector-general and deputy inspector-general that he would “not spare” them, vowing to file cases against them for subjecting Gill to alleged inhuman torture.

Turning his guns towards the additional sessions judge, who sent Gill into physical remand on the police's request, Khan had then said she should brace herself for consequences.

If convicted, Khan could face six months in jail and cannot contest any election for next five years, the GeoTV report added.

The contempt issue adds to charges under anti-terror law that police filed against Khan on Sunday.
