Pierce Butler, Black and White Taxicab Company v…
“ It is very hard to resist the impression that there is one august corpus, to understand which clearly is the only task of any Court concerned. If there were such a transcendental body of law outside of any particular State but obligatory within it unless and until changed by statute, the Courts of the United States might be right in using their independent judgment as to what it was. But there is no such body of law. The fallacy and illusion that I think exist consist in supposing that there is this outside thing to be found. ”
