William Howard Taft,
Old Colony Trust Company v. Commissioner of Internal Revenue…
“ By cases and controversies are intended the claims of litigants brought before the courts for determination by such regular proceedings as are established by law or custom for the protection or enforcement of rights, or the prevention, redress, or punishment of wrongs. Whenever the claim of a party under the Constitution, laws, or treaties of the United States takes such a form that the judicial power is capable of acting upon it, then it has become a case. ”
