Pursuant to statute, 28 U.S.C. §§ 351 et al. and the Rules for Judicial Conduct and Judicial Disability Proceedings (pdf), any person may file a written complaint with the Circuit Executive concerning the actions or behavior of a judge of this court. The form that may be used for a complaint is provided at the end of the rules and can be found here (pdf).
Please note the following to avoid the rejection or summary dismissal of your complaint:
The Federal Circuit posts public orders pertaining to judicial misconduct and disability complaints on this page. Usually, the name of the complainant or the judge complained about is not disclosed in an order. Pursuant to the Rules, the orders will be posted when final action on a complaint has been taken and the order is no longer subject to review.
