(a) When there is a cause to refuse an application or to suspend or revoke the license of any polygraph examiner, the Division shall, not less than thirty days before refusal, suspension, or revocation action is taken, notify such person by certified mail at the last address supplied to the Division by such person of such impending refusal, suspension, or revocation, the reasons therefor, and of his right to an administrative hearing for the purpose of determining whether or not the evidence is sufficient to warrant the refusal, suspension, or revocation action proposed to be taken by the Division.

If within twenty days after such notice has been deposited in the United States mail such person has not made a written request to the Division for an administrative hearing, the Division is authorized to suspend or revoke the polygraph examiner’s license without a hearing. Upon receipt by the Division of a written request of such person within the twenty-day period as set out above, an opportunity for an administrative hearing shall be afforded as early as is practicable. In no case shall the hearing be held less than ten days after written notification thereof, including a copy of the charges, shall have been given the person by certified mail sent to the last address supplied to the Division by the applicant or licensee. The administrative hearing in such cases shall be before the Division Chief.

(b) The Division shall conduct the administrative hearings and it is authorized to administer oaths and issue subpoenas for the attendance of witnesses and the production of relevant books, papers and documents. On the basis of the evidence submitted at the hearing, the Division shall take whatever action it deems necessary in refusing the application or suspending or revoking the license.
