Charles Evans Hughes, Crowell v. Benson — Opinion of the Court
“ Congress has repeatedly exercised authority to confer upon the tribunals which it creates, be they administrative bodies or courts of limited jurisdiction, the power to receive evidence concerning the facts upon which the exercise of federal power must be predicated, and to determine whether those facts exist. The power of Congress to provide by legislation for liability under certain circumstances subsumes the power to provide for the determination of the existence of those circumstances. It does not depend upon the absolute existence in reality of any fact. ”
