The custodian may require a person or government unit that wishes to inspect or copy a public record to submit a written request to the custodian. Otherwise, the custodian shall make public records available for inspection or copying. The custodian shall require a written request if the custodian reasonably believes that: The Public Information Act or any other law may prevent the disclosure of the record to the applicant; or A written request will materially assist MIEMSS in responding to the request.
