1720.435—Official notice.
Official notice may be taken of any material fact which might be judicially noticed by a District Court of the United States, any matter in the public official records of the Office of Interstate Land Sales Registration or any matter which is peculiarly within the knowledge of the administrative law judge. When any decision of an administrative law judge rests, in whole or in part, upon the taking of official notice of a material fact not appearing in evidence of record, opportunity to disprove such noticed fact shall be granted any party making timely request therefor.
