(2) A person in respect of whom a polling agent makes a declaration in accordance with subsection (1) or who the Presiding Officer has reasonable cause to believe has committed the offence of personation shall not, by reason, be prevented from voting, but the Presiding Officer shall cause the words “protested against for personation” to be placed against his name in the marked copy of the Register of Voters or part of the Register of Voters; but where a person in respect of whom a declaration is made admits to the Presiding Officer that he is not the person he held himself out to be, he shall not be permitted to vote if he has not already done so.
