Removal of officers

The board of commissioners shall have power to remove the city attorney, city clerk, city treasurer, police judge, city engineer or city assessor for incompetency, neglect of duty, or malfeasance in office, upon charges preferred, after due notice in writing and opportunity to be heard in their defense. When such charges are sustained any such officers shall be removed by resolution of the board of commissioners, passed by a vote of at least two of the members of said board, declaring that the charges preferred have been proven and that such office is vacant. But said board may in its discretion, by a majority vote of all the members thereof, remove with or without cause the incumbent of any other appointive city office or employment whatever, and may by ordinance prescribe, limit or change the salary of all appointive officers or employees, except that the salary of all appointive officers shall not be increased or diminished during the term for which they are appointed.
