When dealing with the distribution of powers between the General Government and the States, Chief Justice Marshall declared: 'When the American people created a national legislature, with certain enumerated powers, it was neither necessary nor proper to define the powers retained by the States. Those powers proceed, not from the people of America, but from the people of the several States, and remain after the adoption of the Constitution what they were before, except in so far as they may be abridged by that instrument'.
