(1) Time and Manner. Any appeal to the Board from the determination of the Administrative Law Judge must be made within 15 calendar days of the mailing of the findings of fact unless such time limit is extended by the Board upon a showing of good cause. If the fifteenth day falls on a Saturday, Sunday or legal holiday, the appeal may be filed with the Board on the next business day. The appeal shall be in writing and must state why appellant believes there was either error or abuse of discretion on the part of the Administrative Law Judge. The filing of an appeal will stay only that portion of any Administrative Law Judge's decision which permits payment, refund, offsetting or adding rent.
(2) Record on Appeal. Upon receipt of an appeal, the entire administrative record of the matter, including the appeal, shall be filed with the Board.
(3) Appeals. The Board shall, in its discretion, hear appeals. In deciding whether or not to hear a given appeal, the Board shall consider, among other factors, fairness to the parties, hardship to either party, and promoting the policies and purposes of this Chapter, in addition to any written comments submitted by the Administrative Law Judge whose decision is being challenged. The Board may also review other material from the administrative record of the matter as it deems necessary. A vote of three members shall be required in order for an appeal to be heard.
