The legislative authority of any city or village may by a two-thirds vote of its members, and upon petition of ten per centum of the electors shall forthwith, provide by ordinance for the submission to the electors, of the question, "Shall a commission be chosen to frame a charter." The ordinance providing for the submission of such question shall require that it be submitted to the electors at the next regular municipal election if one shall occur not less than sixty nor more than one hundred and twenty days after its passage; otherwise it shall provide for the submission of the question at a special election to be called and held within the time aforesaid. The ballot containing such question shall bear no party designation, and provision shall be made thereon for the election from the municipality at large of fifteen electors who shall constitute a commission to frame a charter; provided that a majority of the electors voting on such question shall have voted in the affirmative. Any charter so framed shall be submitted to the electors of the municipality at an election to be held at a time fixed by the charter commission and within one year from the date of its election, provision for which shall be made by the legislative authority of the municipality in so far as not prescribed by general law. Not less than thirty days prior to such election the clerk of the municipality shall mail a copy of the proposed charter to each elector whose name appears upon the poll or registration books of the last regular or general election held therein. If such proposed charter is approved by a majority of the electors voting thereon it shall become the charter of such municipality at the time fixed therein.
