ISLAMABAD - Senior PPP leader Barrister Chaudhry Aitzaz Ahsan has said that money-laundering case against President Asif Ali Zardari can be reopened if Pakistan formally approaches Swiss judicial authorities. Aitzaz was replying to a query on Monday during a press conference outside the Supreme Court. There were many clauses, sub-clauses and sanctions in various Articles of the Constitution to bring back the looted money from abroad, he argued. He explained the cases would be reinitiated according to international laws. He said, Money-laundering case would be decided according to the state law of Switzerland. However, he said, under UN conventions, no case could be pursed against the president of any country. The leaders always enjoyed immunity under these conventions, he added. Aitzaz said the impeachment was the only way to remove President Zardari. The President enjoys immunity in criminal suits under Article 247 and 248 of the Constitution, however this indemnity is not applicable in civil suits, he explained. Aitzaz said if any court disqualified the President, only the joint session of the Parliament could decide on the case. A simple majority would be needed to table the impeachment motion in the Parliament, he added. The detailed verdict given by the 13-member bench of the apex court headed by Justice Khalil-ur-Rehman Ramday in 2007 mentions that the President has no immunity from proceedings in civil cases, he recalled. He further said the parliamentarians enjoyed immunity to some extent, however the sitting president and governors were immune under 1973 Constitution. Seemingly careful in expressing his views, Aitzaz observed in his brief talk with media persons that former president Pervez Musharraf could be tried for the November 3 arrest case. He said he never accepted Musharraf as the president of Pakistan.
