  by the High Court.
  (3) The High Court may also appoint Additional Sessions Judges and Assistant
  
  Sessions Judges to exercise jurisdiction in a Court of Session.
  (4) The Sessions Judge of one sessions division may be appointed by the High

  case he may sit for the disposal of cases at such place or places in the other
  
  division as the High Court may direct.
  (5) Where the office of the Sessions Judge is vacant, the High Court may make
