(1) On receipt of intimation under rule 27-O from a classified service voter in regard to his proxy, the returning officer shall mark “CSV” against the name of such voter in the last part of the electoral roll containing the names of all service voters so as to indicate that the said voter has appointed his proxy, and the returning officer shall—
(a) If it is an intimation received before the last date for making nominations in the constituency, ensure that no postal ballot paper is issued to such classified service voter; and
(b) if it is an intimation received after the said last date, ensure that a postal ballot paper is issued to such classified service voter for the election then in progress, in accordance with the provisions contained in Part III of these rules.
(2) The returning officer shall also prepare, and maintain up-to-date, a separate list of all classified service voters who have given intimation of their proxies under rule 27-O, and also of all such proxies with their complete addresses, in such form and such manner as the Election Commission may specify from time to time.
(3) As soon as may be after the last date for making nominations in the constituency, the returning officer shall, on the basis of the list maintained under sub-rule (2) and subject to such further direction as the Election Commission may give in this behalf, prepare or cause to be prepared polling station-wise sub-lists of all classified service voters and their proxies having regard to the residential address of each such classified service voter as given in the electoral roll.
(4) Each sub-list prepared under sub-rule (3) shall thereafter be caused to be added by the returning officer at the end to the relevant part of the electoral roll pertaining to each polling station concerned, and such relevant part of the electoral roll together with the said sub-list shall be deemed to be the copy of the electoral roll to be used as the marked copy of the electoral roll under rule 33A or, as the case may be, under rule 49F during the poll at the polling station concerned.
