An appeal shall stay all legal proceedings in furtherance of the action appealed from, unless the official from whom the appeal is taken certifies to the Board, after the notice of appeal shall have been filed with the official, that by reason of facts stated in the certificate a stay would, in the official's opinion, cause imminent peril to life or property. In such case proceedings shall not be stayed otherwise than by a restraining order, which may be granted by the Board or by a court of record on application, on notice to the official from whom the appeal is taken, and on due cause shown.
