If, however, more than 28 months remain in the unexpired term of a commissioner, at the time of appointment, the appointment shall be until the next general election, at which time the vacated office of commissioner shall be filled by election for the remainder of the term. All other vacancies in nomination shall be filled in accordance with the provisions of the Election Code.
The president and commissioners elected under this Section shall serve without compensation.
