Computed by Benchlight The Supreme Court publishes no panel, because every participating justice takes part. Benchlight therefore lists the justices commissioned and in active service on May 21, 2026, from Federal Judicial Center service records. Recusals are shown only where the source records them, so a justice who did not participate may still appear here.
