Paragraph 29 Challenge of voter
If at the time a person applies for a ballot paper for the purpose of voting in person, or after such person has applied for a ballot paper for that purpose and before such person has left the polling station, a candidate or such candidate’s election or polling agent–
declares to the presiding officer that such candidate has reasonable cause to believe that the applicant has committed an offence of personation; and
undertakes to substantiate the charge in a court of law,
the presiding officer may order a constable to arrest the applicant, and the order of the presiding officer shall be sufficient authority for the constable so to do.
A person against whom a declaration is made under this rule shall not by reason of it be prevented from voting.
A person arrested under the provisions of this rule shall be dealt with as a person taken into custody by a constable for an offence without a warrant.
