When the hearing has been held before a hearings officer, the hearings officer, as expeditiously as possible, after the close of the hearing, shall file with the authority a recommended decision together with separate findings of fact, conclusions of law, and a recommended order. The decision, findings of fact, conclusions of law, and any order recommended by the hearings officer shall be based upon the whole record and supported by the reliable probative and substantial evidence, including facts of which the hearings officer properly took judicial notice.
