RSA 38:3: By Cities.

Any city may initially establish such a plant after 2/3 of the members of the governing body shall have voted, subject to the veto power of the mayor as provided by law, that it is expedient to do so, and after such action by the city council shall have been confirmed by a majority of the qualified voters at a regular election or at a special meeting duly warned in either case. Such confirming vote shall be had within one year from the date of the vote to establish such a plant, and if favorable, shall create a rebuttable presumption that such action is in the public interest. If the vote is unfavorable, the question shall not be again submitted to the voters within 2 years thereafter.
