In a statement issued here on Monday, he said that the police must register the FIR against anybody being accused by the lawyer.
Mushahidullah noted that the recent decision of General Pervez Musharraf to ignore Chief Justice's recommendations in the appointment of Supreme Court Judges had rightly disturbed the lawyers' community.
He accused that the present rulers had already damaged the sanctity of the entire institution of judiciary with arbitrary actions.
The PML (N) leader said that Khairi had approached the Chief Justice of Pakistan in a said matter and the latter must take action to preserve the dignity of higher judiciary.
