Section 504. Appointment and removal of commissioner of jurors

(a) Except
  in counties within cities having a population of one  million  or  more,
  the   county  jury  board,  or  a  majority  thereof,  shall  appoint  a
  commissioner of jurors for a term of  four  years  and  shall  fill  any
  vacancy  occurring  in  such  office  in  the same manner as an original
  appointment. The county jury board may, in its discretion,  appoint  the
  county   clerk   or  other  county  officer  or  employee  to  serve  as
  commissioner of jurors. A county clerk's term of office as  commissioner
  shall be coterminus with his term of office as county clerk.
    (b)  The  commissioner  shall  be removable for cause by the appellate
  division of the supreme court in the judicial department  embracing  the
  county,  upon  written  charges  and  opportunity  to be heard after due
  notice thereof. If such commissioner is the county clerk, the  appellate
  division  may  remove  him  from  the office of commissioner in the same
  manner.
