Section 800 - Denial of registration; complaints; notice of hearing1. Denial of registration. The secretary shall, before making a final determination to deny an application for a registration, notify the applicant in writing of the reasons for such denial and shall afford the applicant an opportunity to be heard in person or by counsel prior to the denial of the application. Such notification shall be served personally or by mail or in any manner authorized by the civil practice law and rules for service of a summons. If a hearing is requested, such hearing shall be held at such time and place as the secretary shall prescribe. If the applicant fails to make a written request for a hearing within thirty days after receipt of such notification, then the notification shall become the final determination of the secretary. If, after hearing, the registration is denied, written notice of such denial shall be served upon the registrant personally or by certified mail or in any manner authorized by the civil practice law and rules.2. Revocation, suspension, reprimands, fines. The secretary shall, before revoking or suspending any registration or imposing any fine or reprimand on the holder of such registration, or before issuing any order directing the cessation of unregistered activity shall send notification of such action to the holder. Such notice shall be provided at least ten days prior to the date set for the hearing, notify the registrant or the person deemed to have engaged in such unregistered activities, of any charges made and shall afford the person an opportunity to be heard in person or by counsel in reference thereto. Such written notice may be served upon the registrant in person or by mailing the notice by certified mail to the registrant to the last known business address of such person, or by any method authorized by the civil practice law and rules for the service of a summons. The hearing shall be at such time and place as the secretary shall prescribe. After the applicant is notified of such denial, in the event a certificate of registration or temporary certificate of registration or an application is denied, no such registration shall be issued to such former registrant or applicant for at least six months, nor thereafter, except at the discretion of the secretary. The applicant or registrant may be heard in person or by counsel. Such hearing shall be at such time and place as the secretary shall prescribe.3. In any hearing held pursuant to the provisions of this article, the secretary acting by such officer or person in the department as he or she may designate, shall have the power to subpoena and bring before the officer or person so designated any person in this state, or document, record or relevant evidence, and administer an oath to and take the testimony of any such person or cause his or her deposition to be taken. A subpoena issued under this section shall be regulated by the civil practice law and rules.
