Felix Frankfurter,
Sutton v. Leib — Concurrence
“ Illinois is free to consult solely her own will whether such a provision in a decree relates merely to ceremony or requires a union with a spouse legally free to marry. On that crucial issue, we are told, there is no Illinois law. By what seems to me undesirable judicial administration, the ascertainment for all I know the formulation-of Illinois law is committed to a federal court which in the very nature of things can render only a tentative and indecisive judgment. ”
