George Sutherland, United States Kennedy v. Tyler…
“ The rule has been firmly established by repeated decisions of this court that the power conferred on a federal court to issue a writ of habeas corpus to inquire into the cause of the detention of any person asserting that he is being held in custody by the authority of a state court in violation of the Constitution, laws, or treaties of the United States, is not unqualified, but is to be exerted in the exercise of a sound discretion. ”
