Former president of Supreme Court Bar Ch Aitzaz Ahsan has said amending the constitution is the right of the parliament and the constitutional amendment can not be challenged in a court. The court can only proposes change. Talking to mediamen outside the Supreme Court, Aitzaz said he respects Chief Justice of Pakistan Iftikhar Mohammed Chaudhry more than the President and the Prime Minister. "If anyone thinks he has committed contempt of the court can file petition against him," he said.
