The board shall declare the office of a board member vacant if it finds any of the following:
The incumbent has died or resigned.
The incumbent has been removed or recalled from office or the election of the incumbent thereto has been declared void by the judgment of a court.
The incumbent has ceased to be a resident of the district from which the incumbent was nominated or elected.
The incumbent has ceased to discharge the duties of office for two consecutive months unless prevented therefrom by sickness or other unavoidable cause or unless excused by the chairperson of the board.
A board member who is nominated or elected by zone and who changes permanent residence from one zone of a district to another zone or who by a change in zone boundaries no longer resides in the zone of nomination or election is entitled to continue to serve as board member until June 30 following the next regular district election at which a successor shall be elected by the electors to serve for the remainder of the unexpired term, if any. The successor shall take office July 1 next following the election.
When a vacancy is declared under subsection (1) of this section, the remaining board members shall meet and appoint a person to fill the vacancy from any of the electors of the district if the position is one filled by both nomination and election at-large, and otherwise from any of the electors of the zone from which the vacancy occurs.
If the offices of a majority of the board members are vacant at the same time, the governing body of the principal county shall appoint persons to fill the vacancies from any of the electors of the district if the positions are filled by both nomination and election at-large, and otherwise from any of the electors of the zone from which the vacancy occurs.
The period of service of a board member appointed under subsection (3) or (4) of this section commences upon appointment and expires June 30 next following the next regular district election at which a successor is elected. The successor shall be elected to serve the remainder, if any, of the term for which the appointment was made. If the term for which the appointment was made expires June 30 after the election of the successor, the successor shall be elected to a full term. In either case, the successor shall take office on July 1. [1971 c.513 §27; 1975 c.647 §31; 1977 c.149 §5; 1983 c.350 §203; 2003 c.576 §436]
