Section 23

The notice of appeal shall be served on all parties directly affected by the appeal, and it shall not be necessary to serve parties not so affected; but the court may direct notice of the appeal to be served on all or any parties to the proceedings, or upon any other person, and in the meantime may postpone or adjourn the hearing of the appeal upon such terms as seem just, and may make such order as might have been made if the persons served with the notice had been parties originally.
