17-47. a. If a majority of the qualified electors voting on the proposed ordinance shall vote in favor thereof, such ordinance shall thereupon become a valid and binding ordinance of the municipality and be published as in the case of other ordinances. No such ordinance shall be amended or repealed within 3 years immediately following the date of its adoption by the voters, except by a vote of the people. The council may, within 3 years immediately following the date of adoption of the ordinance, submit a proposition for the repeal or amendment of that ordinance to the voters at any succeeding general election or regular municipal election. If the proposition submitted shall receive a majority of the votes cast at that election, the ordinance shall be repealed or amended accordingly. If the provisions of two or more measures approved or adopted at the same election conflict then the measure receiving the greatest affirmative vote shall control.
b. Notwithstanding the provisions of this section, an ordinance proposed by petition to increase or decrease the term of office of the members of the governing body or the number of members of the governing body, or the division of the municipality into a number of wards, shall not be submitted to the voters of the municipality more than once in any 10-year period.
