The petitions were filed by MQM leaders Farooq Sattar and Senator Dr Farogh Naseem.
The petitions stated that drawing new constituency boundaries in the city is illegal and unconstitutional and that it could not be conducted without census and house count in Karachi.
The petitions said that singling out Karachi for the delimitation process reflects a “biased” conduct of authorities, demanding that new constituencies should be drawn across the country.
The petitioners prayed to the court to review its November 26 and 28 orders it issued while hearing a suo moto notice regarding law and order in the city.
The court has also ordered the Election Commission of Pakistan to draw new electoral constituencies in consultation with political parties besides conducting a door-to-door verification of electoral rolls in Karachi with assistance of army and Frontier Constabulary.
On Thursday, ECP Chairman Justice (r) Fakhruddin G Ibrahim rejected MQM’s reservations and vowed that the task of drawing up new constituency boundaries would be completed in the light of the apex court orders.
Meanwhile, Farooq Sattar said the SC verdict on delimitation of constituencies amounts to pushing the MQM mandate to the wall. “Only Karachi specific delimitation of constituencies order is unfair and unjust. This order is based on discrimination and is sheer injustice with us. This verdict runs contrary to law and constitution as no ambiguity exists in law and constitution in this regard,” he said while talking to the media after filing petitions in the SC.
He said the ECP had received SC orders on delimitation of constituencies a year before in Karachi law and order case wherein it was laid down that process of redrawing of constituencies be carried out in Karachi as per spirit of law and constitution. “It is strange that the ECP could not remember its discretionary powers during the entire period of the year and now it is exercising its discretionary powers all of a sudden,” he said.
“No redrawing of constituencies could be carried out without holding population census in any country and if this process is to be undertaken under someone’s whim and wish then this process should be implemented all over the country,” Farooq Sattar said.
He said if the ECP invites objections from across the country in respect of constituencies and it does not receive complaints from all the 272 constituencies “then we are ready to withdraw from politics”.
