BACKGROUND
In the General Elections 2013, Sardar Ayaz Sadiq had, from PML-N’s platform, defeated Pakistan Tehrik-i-Insaf chairman Imran Khan. Ayaz Sadiq had secured 93,389 votes whilst Imran polled 84,517 votes.
PTI had challenged Ayaz Sadiq’s victory by alleging rigging and filing a petition to challenge the result. When proceedings for the case began in July 2013, Ayaz Sadiq obtained a stay order. When the stay order expired in November 2014, a commission was formed, headed by Justice Ghulam Hussain Awan.
As per directions of the commission, recounting and verification of votes were conducted by NADRA.
As per the commission’s report, 23,595 counter foils were not signed and stamped. 108,115 votes were declared as correct, 3,642 votes could not be verified whereas 2,693 votes did not contain the signatures of the staff . 750 votes were not stamped by the presiding officer. After listening to the cases of both parties and taking into account the evidence collected, the tribunal ordered reelection on the NA seat, thus de-seating the National Assembly speaker.
