Section 2322. Final determination; procedure on orders without hearing

(a)
  After  a  final  determination  against  an  insurer,  the amount of any
  overcharge  received  by  such  insurer  during  the  pendency  of   the
  proceedings, with interest thereon, shall upon demand be refunded by the
  insurer to the persons entitled thereto.
    (b)   Any   insurer   or   rate  service  organization  to  which  the

  superintendent  for  a  hearing.    Pending  a  hearing  and  a decision
  affirming,   reversing   or   modifying   his   previous   action,   the
  superintendent  may  suspend  or  postpone  the  effective  date  of his
  previous action.
