§ 463. Denial of permit; notice of hearing. The department shall, before making a final determination to deny an application for a permit, notify the applicant in writing of the reasons for such proposed denial and shall afford the applicant an opportunity to be heard in person or by counsel prior to denial of the application. Such notification shall be served personally or by certified 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 department 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 of denial shall become the final determination of the department. The department, acting by such officer as the commissioner may designate, shall have the power to subpoena and bring before the officer any person in this state, and administer an oath to and take testimony of any person or cause his deposition to be taken. A subpoena issued under this section shall be regulated by the civil practice law and rules. If, after such hearing, the application is denied, written notice of such denial shall be served upon the applicant personally or by certified mail or in any manner authorized by the civil practice law and rules for the service of a summons.
