This appeal arises from an election petition filed by Shyamdeo Pd. Singh (the appellant) challenging the election of Nawal Kishore Yadav (the respondent) to the Bihar Legislative Council from the ... Patna Teachers Constituency. The primary ground for the challenge was the alleged registration and enrolment of a large number of ineligible persons as electors, which the appellant claimed materially affected the election result. The Designated Election Judge dismissed the election petition, leading to this appeal before the Supreme Court.
