An election petition calling in question any election can be presented on one or more of the following grounds: a) that on the date of the election a returned candidate (a candidate who has been declared elected) was not qualified; b) that some corrupt practice was committed by a returned candidate or his election agent; c) that any nomination was improperly rejected; and d) that the result was materially affected. If any of these is true, the High Court where the petition is submitted declares the election of the returned candidate to be void. A petition can be submitted by any candidate or elector within 45 days of the declaration of the result.
