ISLAMABAD - Describing withdrawal of controversial NAB Ordinance as victory of the rule of law, PML-N Senator Zafar Ali Shah said that Constitutions violation if proven on part of the President could lead to impeachment proceedings. Senator Shah had firstly challenged the National Accountability (Amendment) Ordinance promulgated by President Asif Ali Zardari over a couple months ago in the Upper House and later on in the apex court. Now Shah is also one of petitioners that had challenged the controversial Ordinance in the Supreme Court of Pakistan that is currently hearing the case. The case took a new turn on Thursday when the Attorney General informed the apex court that the government has decided to withdraw the Ordinance in question. The court sought the withdrawal but I have pleaded that withdrawal does not affect my petition. I have pleaded that withdrawal was meaningful for a valid orders or Ordinance, Shah told this scribe. And in case the court upholds my point that the President has violated the Constitution by promulgating an invalid or unlawful ordinance, that could lead to impeachment proceedings against the head of the state, he maintained. Asked whether his party being main opposition party would go to that extent of initiating impeachment proceedings against President Zardari, he was simply unable to answer on behalf of the PML-N. Hectic efforts to get the latest version of the party on this issue from stalwarts like Leader of the Opposition in National Assembly Chaudhary Nisar Ali Khan, Chairman PML-N Raja Zafarul Haq, Ahsan Iqbal, and Senator Ishaq Dar could not succeed till filing of this report. Elaborating his point, Shah said there were two basic situations that necessitate impeachment proceedings against a President, which was for sure the prerogative of the Parliament and not that of any party or person; Firstly if the President lacks mandate both politically and administratively due to any reasons, and secondly if the President violates the Constitution, he added. Therefore, he was of the view that decision of the court on this case would have far reaching implications on the domestic politics as this mysterious promulgated ordinance had impacted Prime Minister, the President and the Parliament. So far a new Accountability Bill is pending due to difference of opinion on the key issues between the PML-N and the PPP. The PML-N has been seeking provisions enabling repatriation of looted national wealth transferred to others countries while the Minister for Law and Justice and Parliamentary Affairs Babar Awan has been opposing it. Secondly, the PML-N seeks the provision in the new NAB law in the making for the last many months to have a retired if not serving judge of Supreme Court as Chairman of the National Accountability outfit.
