All towns, when lawfully assembled for any purpose other than the election of town officers, and all societies and other municipal corporations when lawfully assembled, shall choose a moderator to preside at such meetings, unless otherwise provided by law; and, except as otherwise provided by law, all questions arising in such meetings shall be decided in accordance with standard parliamentary practice, and towns, societies and municipal corporations may, by ordinance, adopt rules of order for the conduct of their meetings. At any such town meeting the moderator shall be chosen from the last-completed registry list of such town. Two hundred or more persons or ten per cent of the total number qualified to vote in the meeting of a town or other municipal corporation, whichever is less, may petition the clerk or secretary of such town or municipal corporation, in writing, at least twenty-four hours prior to any such meeting, requesting that any item or items on the call of such meeting be submitted to the persons qualified to vote in such meeting not less than seven nor more than fourteen days thereafter, on a day to be set by the town meeting or, if the town meeting does not set a date, by the town selectmen, for a vote by paper ballots or by a “Yes” or “No” vote on the voting machines, during the hours between twelve o’clock noon and eight o’clock p.m.; but any municipality may, any provision of any special act to the contrary notwithstanding, by vote of its legislative body provide for an earlier hour for opening the polls but not earlier than six o’clock a.m. The selectmen of the town may, not less than five days prior to the day of any such meeting, on their own initiative, remove any item on the call of such meeting for submission to the voters in the manner provided by this section or may submit any item which, in the absence of such a vote, could properly come before such a meeting to the voters at a date set for such vote or along with any other vote the date of which has been previously set. The paper ballots or voting machine ballot labels, as the case may be, shall be provided by such clerk or secretary. When such a petition has been filed with such clerk or secretary, the moderator of such meeting, after completion of other business and after reasonable discussion, shall adjourn such meeting and order such vote on such item or items in accordance with the petition; and any item so voted may be rescinded in the same manner. If such moderator resigns or is for any other cause unable to serve as moderator at such adjourned meeting, such clerk or secretary shall serve, or may appoint an elector of such municipality to serve, as moderator of such adjourned meeting. Such clerk or secretary, as the case may be, shall phrase such item or items in a form suitable for printing on such paper ballots or ballot labels, provided that the designation of any such item shall be in the form of a question, as prescribed under section 9-369. The vote on any item on the call of a town or other municipal corporation shall be taken by paper ballot if so voted at the meeting, if no petition has been filed under this section with reference to such item.
