LAHORE A five-member bench of the Lahore High Court on Tuesday directed petitioner AK Dogar to produce more material in support of his contention that President Asif Ali Zardari is doing party politics while unlawfully holding dual offices of President, as well as Co-Chairman PPP. The bench adjourned till June 21 hearing of the three identical petitions, challenging Asif Ali Zardaris holding of office of PPP Co-Chairman and President of Pakistan at one and the same time. The bench comprised Justice Ijaz Ahmad Chaudhry, Justice Iftikhar Hussain, Justice Umar Ata Bandial, Justice Iqbal Hameed-ur-Rehman and Justice Ijaz-ul-Ahsan. The petitions have been filed on behalf of Pakistan Lawyers Forum through Advocate A K Dogar, Engineer Ghulam Jilani and Asif Mahmood Khan Advocate. On Tuesday, AK Dogar continued advancing his arguments in detail, asserting that under the Constitution Zardari couldnt be the Head of the State, as well as of a, political party simultaneously, and he should quit one office immediately in respect of the Constitution of Pakistan. He asserted it amounted to subversion of the Constitution. Zardaris counsel SM Masood was present in the court but he would give his arguments later on. Petitioners counsel submitted that President Asif Ali Zardari was continuously holding the office of the Co-Chairman of the PPP alongwith the office of the President of Pakistan, which was a violation of Article 41 (1) of the Constitution. He said that he had already sent a notice on September 25, 2009 to Zardari demanding of him to surrender the office of the Co-Chairman of the PPP but this notice had gone unattended. Dogar said President is the Head of the State and not the head of the government. He is representative of the unity of the Republic and could not participate in politics, he added. According to him, the Apex Court has laid down the principle that the President is required to maintain a neutral image. He said he had collected a number of documents and Press clippings to prove that the President House was functioning as the head office of PPP. Dogar pleaded for directing Zardari to surrender the office of Co-Chairman of PPP. Ghulam Jilani had also requested the court to summon President Asif Ali Zardari in capacity of Co-Chairman PPP in the hearing of two Constitutional petitions, challenging holding of political office by him. A written reply to these petitions, on behalf of the Federal Law Ministry, was submitted in which it was stated that there was no Constitutional bar on President Asif Ali Zardari to hold office of Co-Chairman PPP as it was not a profitable office.
