35 Miss. Code R. § 101-4.20
Upon request or on its own initiative, the Board may require a party to provide the other party in the administrative appeal with a copy of all documents which he intends to provide to the Board in the presentation of his case at the hearing before the Board. Failure to timely provide the other party with a copy of such documents when required to do so may be found by the Board to be an involuntary withdrawal of the administrative appeal or the Board may determine that such documents should not be considered by it in the administrative appeal. In each appeal, when applicable, the Department shall provide the Board and, if it has not already done so, the other party, with copies of all applicable Review Board orders, Review Board minutes, assessments, and audit reports including auditor comments.
