(g) Service of process shall also be made on each person who petitioned the board in the proceeding, provided such person's legal rights, duties or privileges were determined therein. However, failure to make service within fifteen days on parties other than the board shall not deprive the court of jurisdiction over the appeal. If service is not made within fifteen days on a party in the proceeding before the board, the court, on motion of the party or the appellant, shall make such orders of notice of the appeal as are reasonably calculated to notify the party not yet served. If the failure to make service causes prejudice to the board or any party, the court, after hearing, may dismiss the appeal or may make such other orders as are necessary to protect the party prejudiced.
(h) The appeal shall state the reasons on which it has been predicated and shall not stay proceedings on the decision appealed from. However, the court to which the appeal is returnable may grant a restraining order, on application, and after notice to the board and cause shown.
