Thereafter, nonlegislative citizen members shall be appointed for a term of four years. The Commissioner shall serve a term coincident with his term of office. Appointments to fill vacancies, other than by expiration of a term, shall be for the unexpired terms. All members may be reappointed. No nonlegislative citizen member shall serve more than two consecutive four-year terms. The remainder of any term to which a member is appointed to fill a vacancy shall not constitute a term in determining the member’s eligibility for reappointment. Vacancies shall be filled in the same manner as the original appointments.
