The Returning Officer shall stamp on the back of the ballot paper and the counter-foil the letters "EDC". He shall before forwarding such ballot paper, underline the entry and write the letter "EDC" against that entry relating to that elector in the marked copy of the electoral roll relating to the polling station at which the elector is entitled to record his vote denoting that the elector has been issued with a ballot paper.
