At any caucus of the enrolled members of any party in any municipality or in any voting district of any municipality, the chairman of such caucus shall, upon the receipt of a written motion from any person lawfully participating in such caucus calling for a vote by ballot upon such matter as such motion designates, submit such motion to a rising vote; and, if fifteen electors present and legally entitled to participate in such caucus vote in favor of such motion, the vote on the matter specified in such motion shall be by ballot. The presiding officer shall thereupon appoint two tellers; and, upon the written application of fifteen electors legally entitled to participate in such caucus, he shall appoint a teller from the persons whose names appear on such application. Before any ballot is deposited, the name of the elector offering to vote shall be given to the clerk or secretary of such caucus, and such name shall be checked on the enrollment list of such party. No person shall vote or participate or attempt to vote or participate in any caucus of a party in any voting district unless he is enrolled on the last-completed enrollment list of such party in such voting district; provided, if the party rules of such party provide for a joint caucus for two or more voting districts of a municipality, a person may vote in such joint caucus if the voting district in which he is enrolled is participating in such joint caucus. Any person who violates any provision of this section shall be guilty of a class D misdemeanor.
