Iowa Code Title IX. Local Government [Chs. 331-420] § 331.214. Vacancy of supervisor's office

(1) That the supervisor is physically or mentally incapable of performing the duties of office and there is reasonable cause to believe that the supervisor will not be able to perform the duties of office for the remainder of the supervisor's term. To make this determination, the board shall appoint a physician and the family of the supervisor shall appoint a physician to examine the supervisor. For purposes of this subsection, “family” means the parent, spouse, or child of the supervisor. If the family does not appoint a physician, the board shall appoint two physicians to examine the supervisor. The board shall receive the report of the physicians as evidence at the hearing. The board may only declare the supervisor's seat vacant if both physicians concur that the supervisor is physically or mentally incapable of performing the duties of office and there is reasonable cause to believe that the supervisor will not be able to perform the duties of office for the remainder of the supervisor's term. However, if the physicians concur that the supervisor is mentally incapable of performing the duties of office, the board shall not declare the supervisor's seat vacant for one year from the date of the hearing if the supervisor is receiving treatment for the mental incapacity.

(2) That the supervisor refuses or is unavailable for the examination required in subparagraph (1).
