Either board in the execution of the duties for which appointed may subpoena witnesses and in case of contempt may certify such fact to the circuit court having jurisdiction.

The board must consist of not less than three nor more than nine members, a majority of which constitutes a quorum, appointed by the governing authority or authorities of the area served. The members shall serve for overlapping terms of not less than three nor more than five years or until their successors are appointed. A vacancy in the membership must be filled for the unexpired term in the same manner as the initial appointment. Members are removable for cause by the appointing authority upon written charges and after a public hearing. The appointing authorities shall determine the amount of compensation, if any, to be paid to the members of a board of zoning appeals or zoning board of adjustment. None of the members may hold any other public office or position in the municipality or county.
The board shall elect one of its members chairman, who shall serve for one year or until he is reelected or his successor is elected and qualified. The board shall appoint a secretary who may be an officer of the governing authority or of the planning commission. The board shall adopt rules in accordance with the provisions of any ordinance or resolution adopted pursuant to this chapter. Meetings of the board shall be held at the call of the chairman and at such other times as the board may determine. The chairman or, in his absence, the acting chairman, may administer oaths and compel the attendance of witnesses by subpoena. The board shall keep minutes of its proceedings, showing the vote of each member upon each question, or if absent or failing to vote, indicating such fact, and shall keep records of its examinations and other official actions, all of which shall be immediately filed in the office of the board and shall be a public record.
Appeals to the board may be taken by any person aggrieved or by any officer, department, board, or bureau of the municipality or county. Such appeal shall be taken within a reasonable time, as provided by the rules of the board, by filing with the officer from whom the appeal is taken and with the board of appeals notice of appeal specifying the ground thereof. The officer from whom the appeal is taken shall forthwith transmit to the board all the papers constituting the record upon which the action appealed from was taken.
An appeal stays all legal proceedings in furtherance of the action appealed from, unless the officer from whom the appeal is taken certifies to the board, after the notice of appeal shall have been filed with him, that by reason of facts stated in the certificate a stay would, in his opinion, cause imminent peril to life and 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 officer from whom the appeal is taken, and on due cause shown.
The board shall fix a reasonable time for the hearing of the appeal or other matter referred to it, and give public notice thereof, as well as due notice to the parties in interest, and decide the same within a reasonable time. At hearing any party may appear in person or by agent or by attorney.
