The Lahore High Court was told on Monday that Pakistans former ambassador to the USA, Mr Hussain Haqqani, would remain available for investigation into the memo sent by Pakistani-American businessman Mansoor Ijaz to then US Joint Chiefs Chairman Adam Mike Mullen. The investigation itself will be carried out by the parliamentary committee on National Security chaired by Senator Reza Rabbani. At the same time, the Supreme Court cleared for hearing the petitions filed by PML-N chief Mian Nawaz Sharif and other PML-N leaders. Mian Nawaz in his petition has asked for the identification of the person responsible for this dreadful conspiracy and for the setting up of an inquiry. That he did not consider the promised parliamentary commission enquiry to meet his demand is probable, considering that the opposition did not find it met its requirements, and saw it as an attempt to derail its demand for a judicial investigation. The commission into the Abbottabad raid will meanwhile hear testimony from Mr Haqqani on December 14, profiting from his presence in the other matter. Meanwhile, former COAS Gen (retd) Mirza Aslam Beg has said that the government is trying to hush up the case to protect Mr Haqqani. General Beg believed that he would have made startling disclosures if he had been investigated more intensely. The government should realise that an investigation by a parliamentary committee on which it had a built-in majority would leave it open to charges of a cover-up, quite apart from the objections of the opposition. The matter requires a thorough and objective probe which needs the setting up of a judicial enquiry. The parliamentary committee investigation is not properly equipped, particularly with the requisite technical expertise, and the entire nation needs to achieve closure on the incident through an investigation that no one can object to, and which will not be accused of covering up for any person. The Memo scandal should not be considered over after Mr Haqqanis resignation. Parliament is supposed to be supreme, and thus the enquiry by a parliamentary committee has a certain sense, but a judicial commission would be even better, and its results would also be available to Parliament. It must not be forgotten that, whether a parliamentary or judicial enquiry takes place, it is the executive which will have to take action against the guilty parties, and they will be tried by the judiciary.
