Iowa Code Title IX. Local Government [Chs. 331-420] § 376.3. Nominations

Candidates for elective city offices must be nominated as provided in sections 376.4 through 376.9, unless by ordinance a city chooses the provisions of chapter 44 or 45. However, a city acting under a special charter in 1973 and having a population of over fifty thousand shall continue to hold partisan elections as provided in sections 43.112 through 43.118 and sections 420.126 through 420.137, unless the city by election as provided in section 43.112 chooses to conduct city elections under this chapter or chapter 44 or 45. The choice of one of these options by such a special charter city does not otherwise affect the validity of the city's charter. However, special charter cities which choose to exercise the option to conduct nonpartisan city elections may choose, in the same manner the original decision was made, to resume holding city elections on a partisan basis.
