Joseph P. Bradley, Missouri v. Lewis — Opinion of the Court
“ We might go still further, and say, with undoubted truth, that there is nothing in the Constitution to prevent any State from adopting any system of laws or judicature it sees fit for all or any part of its territory. If the State of New York, for example, should see fit to adopt the civil law and its method of procedure for New York City and the surrounding counties, and the common law and its method of procedure for the rest of the State, there is nothing in the Constitution of the United States to prevent its doing so. ”
