Fed. R. Crim. P. 37 - Indicative Ruling on a Motion for Relief That Is Barred by a Pending Appeal
(a) Relief Pending Appeal. If a timely motion is made for relief that the court lacks authority to grant because of an appeal that has been docketed and is pending, the court may:
(1) defer considering the motion;
(2) deny the motion; or
(3) state either that it would grant the motion if the court
of appeals remands for that purpose or that the motion raises a substantial issue.
(b) Notice to the Court of Appeals. The movant must promptly notify the circuit clerk under Federal Rule of Appellate Procedure
12.1 if the district court states that it would grant the motion or that the motion raises a substantial issue.
(c) Remand. The district court may decide the motion if the court of appeals remands for that purpose.
