The governing body of every joint self-insurance program shall be elected by a majority of the members voting in the election. Elections may be conducted during a regular meeting of the governing body or by mail-in ballot or electronic ballot. If mail-in or electronic ballots are used, the ballots are to be counted and secured until certified by the governing body at the same or the next regular meeting and recorded in the meeting minutes. Vacancies on the governing board shall be filled according to program by-laws. Joint self-insurance programs governed by a governing body which requires the inclusion of a voting representative from each member entity in such governing body are exempt from the requirements of this section.
