(a) Each decision is issued by three Board members (see § 16.5(b)), who base their decision on a record consisting of the appeal file; other submissions of the parties; transcripts or other records of any meetings, conferences or hearings conducted by the Board; written statements resulting from conferences; evidence submitted at hearings; and orders and other documents issued by the Board. In addition, the Board may include other materials (such as evidence submitted in another appeal) after the parties are given notice and an opportunity to comment.

(b) The Board will promptly notify the parties in writing of any disposition of a case and the basis for the disposition.
