Vacancies on the system advisory council arising for reasons other than the regular expiration of terms of office may be filled by election or appointment from among the representatives for the unexpired term. If the unexpired term was held by an officer of the council, the representative may be elected or appointed to fill the unexpired term and need not necessarily be that officer. The vacated council office may be filled from among the members already on that council.
