It is all too common for critics to demand an "enforceable" ethics code against the Supreme Court justices. These charges, however, fail to recognize how the complaint system could be weaponized. For evidence of this risk, I would point to ongoing proceedings concerning Judge Stephen Vaden of the Court of International Trade.
Judge Vaden was one of thirteen judges who joined the boycott of Columbia Law School. (I interviewed Judge Matt Solomson of the Court of Federal Claims about the boycott.) Shortly after the boycott was announced, a judicial misconduct complaint was filed against Judge Vaden.
Judge Vaden was not alone. Similar complaints were filed against Judges in the Fifth Circuit, the Eleventh Circuit, and in the Court of Federal Claims. As best as I can tell, each of those complaints was dismissed within the circuit. On June 18, 2024, Chief Judge William Pryor of the Eleventh Circuit dismissed the complaint, and the Judicial Council of the Eleventh Judicial Circuit affirmed. On June 24, Chief Judge Priscilla Richman of the Fifth Circuit dismissed the complaint, and the Appellate Review Panel of the Judicial Council for the Fifth Circuit affirmed. And on October 1, 2024, Chief Judge Elaine D. Kaplan of the Court of Federal Claims dismissed the complaint.
