The selectboard shall promptly and fairly hear any or all appeals by the ratepayer after notice to all interested parties. During appeal, disconnection will be postponed. Upon just cause shown, the selectboard may grant exceptions to any ratepayer. The selectboard may appoint one or more members of the selectboard to act as hearing officers for the purposes of the appeal. Alternatively, the selectboard may appoint a responsible citizen to act as a hearing officer for the appeal. (Added 1977, No. 93.)
