Iowa Code Title IX. Local Government [Chs. 331-420] § 410.17. City marshal

Service by any member of the police department as city marshal shall not deprive the member of any rights under this chapter. In any matter in which said city marshal shall be individually interested and which requires the action of the board of trustees of the police officers' pension fund, the city marshal shall not act as a member of said board, but the mayor of the city shall act with the other two trustees of the board with respect thereto. Upon the termination of the term as city marshal, the member shall regain the rank held in the police department at the time of the member's appointment as city marshal.
