Will jurists of Pakistan, including their Supremo-in-Chief Aitzaz Ahsan, explain the constitutional position on Mr. Zardari's action of keeping two offices of (a) being President of Pakistan and (b) co-chairman of the PPP? Most people believe keeping both these offices is ultra vires of the constitution. They might also helpfully explain the constitutional position of 'Presidential immunity' too? The multiple-hatted presidency was an invention of the military dictator Musharraf who also got it validated from a rubberstamp assembly along with the 17th amendment. Do the jurists of this country find any reason for this constitutional anomaly to continue? -NOOURE ZEENATE JEHAN, Karachi, December 1.
