Where a final decision of the board rests in whole or in part upon official notice of a material fact, such fact shall be clearly and precisely stated in such decision. In determining whether to take official notice of material facts, the presiding officer may consult any source of pertinent information, whether or not furnished as it may be, by any party and whether or not admissible under the rules of evidence.(4)Controversion.
