Mo. R. Civ. P. 83.01
This Court on its own motion or on application of a party may transfer to this Court from the court of appeals a case in which there has been no disposition. The transfer shall be for any of the reasons stated in Rule 83.02 or for the purpose of equalizing the workload of the appellate courts.
Any party requesting such transfer shall file an application in this Court within ten days after the filing of the record on appeal in the court of appeals. In connection with the consideration of an application for transfer under this Rule 83.01, this Court may order the record on appeal forwarded to it.
Applications for transfer filed pursuant to this Rule 83.01 shall not affect the time for filing briefs unless this Court so orders. In the event of transfer under this Rule 83.01, briefs already filed in the court of appeals shall be considered as having been filed in this Court, and briefs not yet filed in the court of appeals on the date of the order of transfer shall be filed directly in this Court within the time prescribed for filing briefs when no transfer is ordered.
