Felix Frankfurter,
Theard v. United States — Opinion of the Court
“ While a lawyer is admitted into a federal court by way of a state court, he is not automatically sent out of the federal court by the same route. The two judicial systems of courts, the state judicatures and the federal judiciary, have autonomous control over the conduct of their officers, among whom, in the present context, lawyers are included. The court's control over a lawyer's professional life derives from his relation to the responsibilities of a court. ”
