If, in the opinion of the Secretary, disclosure of any public record which is otherwise required to be disclosed under the Act would do substantial injury to the public interest, the Secretary may temporarily deny the request in writing, and apply within 10 working days of the denial to the appropriate circuit court for an order permitting the Secretary to continue to deny or restrict the disclosure. Notice of the application filed with the circuit court shall be served upon the applicant in the same manner provided for service of process by the Maryland Rules of Procedure.
