Mississippi Code Title 9. Courts § 9-3-39

The Supreme Court shall have power to make such rules in respect to making out records for said court and for the Court of Appeals as may be expedient, and may prescribe the form and manner in which records shall be prepared for appeal, and cause the same to be bound, but shall not require any record to be printed; and may enforce its rules by proper fines or by refusal to allow costs to be taxed to the clerks below on records not made out according to the rules, or by refusing to permit such records to be filed. And the court may prescribe the mode of pleading in causes therein, civil and criminal, and the manner of trying the same; and may also establish such rules of practice and proceedings therein as may be deemed necessary and proper for certainty and dispatch of business, and may dismiss causes for noncompliance with any of the rules; but such rules must be consistent with law.
