Stephen Johnson Field,
Chicago and Northwestern Railway Company v…
“ The judicial power of the United States extends by the Constitution to controversies between citizens of different States as well as to cases arising under the Constitution, treaties, and laws of the United States, and the manner and conditions upon which that power shall be exercised, except as the original or appellate character of the jurisdiction is specially designated in the Constitution, are mere matters of legislative discretion. In some cases, from their character, the judicial power is necessarily exclusive of all State authority ”
