(a) In cases where directors have entered the services of the United States Armed Forces or its allies, temporary vacancies on such boards are declared to exist until the end of the terms of the members or until their return to civilian life in the school district if their return occurs before the expiration of their elected terms.
(b) These vacancies shall be filled in the manner prescribed by law, except that appointments of the successors shall be conditional upon the return of the members to resume their normal civilian activities in the school district. Upon return, they may resume their duties as directors for their unexpired terms by written notice to the secretaries of their respective school district boards of directors.
(c) Directors appointed under the provisions of this section shall take the required oath of office and conform in all respects to legal provisions regarding directors.
(d) Directors serving in the United States Armed Forces shall be eligible for reelection in the usual manner prescribed by law. If reelected, the procedure for filling the temporary vacancies provided herein shall be again followed in the appointment of the successors to the absentees, and all other provisions of this section shall prevail.
(e) If there is a majority of the directors left after the absences mentioned in this section, such majority may act without notice to those so absent as fully and as effectively as if all directors were present.
(f) If there is more than a majority remaining after such absences, notice must be given for a reasonable length of time before the meeting to directors not so absent of the time, place, and purpose of a meeting of the school district board of directors, unless the meeting is a regular and not a special or called meeting.
