After publication of the population of the municipality according to the 1980 decennial census, the governing authorities of the municipality shall designate the geographical boundaries of new wards as provided in this subparagraph. Each ward shall contain as nearly as possible the population factor obtained by dividing by four (4) the city's population as shown by the 1980 and each most recent decennial census thereafter. It shall be the mandatory duty of the council to redistrict the city by ordinance, which ordinance may not be vetoed by the mayor, within six (6) months after the official publication by the United States of the population of the city as enumerated in each decennial census, and within six (6) months after the effective date of any expansion of municipal boundaries; provided, however, if the publication of the most recent decennial census or effective date of an expansion of the municipal boundaries occurs six (6) months or more prior to the first primary of a general municipal election, then the council shall redistrict the city by ordinance within at least sixty (60) days of such first primary. If the publication of the most recent decennial census occurs less than six (6) months prior to the first primary of a general municipal election, the election shall be held with regard to currently defined wards; and reapportioned wards based on the census shall not serve as the basis for representation until the next regularly scheduled election in which council members shall be elected. If annexation of additional territory into the municipal corporate limits of the city shall occur less than six (6) months prior to the first primary of a general municipal election, the city council shall, by ordinance adopted within three (3) days of the effective date of such annexation, assign such annexed territory to an adjacent ward or wards so as to maintain as nearly as possible substantial equality of population between wards. Any subsequent redistricting of the city by ordinance as required by this section shall not serve as the basis for representation until the next regularly scheduled election for city councilmen.
The method of electing the mayor and councilmen shall be the same as otherwise provided by law except as provided in this chapter. The mayor and councilmen elected hereunder shall hold office for a term of four (4) years and until their successors are elected and qualified. No person shall be eligible to the office of mayor or councilman unless he is a qualified elector of such city.
