10th Cir. R. 42.1: Dismissal for failure to prosecute

When an appellant fails to comply with the Federal Rules of Appellate Procedure or these rules, the Clerk will notify the appellant that the appeal may be dismissed for failure to prosecute unless the failure to comply is remedied within a designated time. If the appellant fails to comply within that time, the Clerk will enter an order dismissing the appeal and issue a copy of the order as the mandate. The appellant may not remedy the failure to comply after the appeal is dismissed, unless the court orders otherwise.
