If, in the opinion of the Departmental custodian, disclosure of any public record which is otherwise required to be disclosed would do substantial injury to the public interest, he may temporarily deny this request in writing. In these cases, the Departmental custodian, after obtaining approval from the Secretary or his designee, shall apply to the appropriate circuit court for an order permitting him to continue to deny or restrict this disclosure. Notice of the application filed with the circuit court shall be served upon the applicant by the Departmental custodian in the same manner provided for service of process by the Maryland Rules of Procedure.
