D.c Ct. App. 38
As amended through April 11, 2024
When a party to a proceeding before this court or an attorney practicing before the court takes an appeal or files a petition or motion that is frivolous or interposed for an improper purpose, such as to harass or to cause unnecessary delay, or fails to comply with an order of this court, the court may, on its own motion or on motion of a party, impose appropriate sanctions on the offending party, the attorney, or both. Before doing so on its own motion, the court will give the party notice and an opportunity to respond. Sanctions that may be imposed include dismissal of the appeal; imposition of single or double costs, expenses, and attorneys' fees; and disciplinary proceedings.
