You do not have to do anything. You do not actually have to attend the hearing if you do not desire to attend. The Administrative Hearing is held because you requested it or because the law requires that there be an independent review of the OSBI's decision. The Hearing Examiner's role is to decide whether or not the OSBI had evidence to support its action (license denial, suspension, revocation, or an administrative fine.) The burden of proof is on the OSBI. You do, however, have the opportunity to give opening and closing statements, cross examine any witnesses the OSBI presents, object to any exhibits or testimony, testify yourself and present witnesses and exhibits on your own behalf, if you wish.
