Former president of Supreme Court Bar Association (SCBA) Asma Jehangir has said that the Supreme Court cannot perform all the tasks and every institution must remain within its ambit as provided in the constitution.Talking to media here in Lahore on Wednesday, Asma Jehangir said there were NROs in every one's table drawers and the government will ultimately have to write letter to the Swiss government for reopening of the cases.She said she had always advised the government to respect and implement the verdicts of the judiciary but at the same time she said the court cannot perform all the work and it was in the interests of the institution to remain within their constitutional limit and perform their functions. .In reply to a question, Asma Jehangir said if the government wants to stay in office, it will have to write the letter otherwise the situation would take a dangerous turn. She said she could not fully comprehend the order of the Supreme Court regarding NRO and she has difference of opinion on many verdicts of the apex court. She said it would be difficult to move on if the judiciary is to take the powers of the parliament. She said despite all this, the Supreme Court verdicts must be implemented.
