Nationwide, 552,037 ballots across all assemblies were rejected. Balochistan recorded the highest provincial rate at 2.76%; Sindh the lowest at 0.97%. Punjab’s rate was 1.07% and Khyber Pakhtunkhwa’s 1.69%.

Election Context: 1988

Pakistan’s 1988 general elections were held on 16 November 1988 following the death of General Zia ul-Haq in an aircraft crash on 17 August 1988. They were the first party-based elections in eleven years. Political parties, including the PPP and the Islami Jamhoori Ittehad, contested openly for the first time since 1977. The return of party symbols and familiar party-based voting is consistent with the significant drop in the rejection rate, from 3.33% in 1985 to 1.58% in 1988.

What Is a Rejected Ballot?

A rejected ballot is a ballot paper excluded from the vote count. Polling staff identify and set aside such ballots during the counting process at the polling station. The Returning Officer (RO) then reviews these determinations during the consolidation of results, and the ballot is formally rejected only after that scrutiny. Pakistani electoral procedure specifies four grounds for rejection: the ballot does not bear the presiding officer’s official stamp and signature; it carries any mark or writing beyond the Assistant Presiding Officer’s (APO) official seal and signature; an extraneous paper or material is attached to it; or the voting mark falls simultaneously in the boxes of two candidates in a way that makes it impossible to determine which candidate the voter intended to select.

Rejection does not automatically indicate fraud or deliberate misconduct. Voter error — including accidental double-marking or stamps placed outside the designated box — accounts for a documented share of rejections in every election.
