The Constitution of the United States of America…
“ The Fourteenth Amendment does not impair the authority of the States to determine finally, according to their settled usages and established modes of procedure, issues which do not involve any right secured by the Constitution, an act of Congress, or a treaty. As long as a local tribunal acts in consonance with the Constitution, laws and procedure of its own State and as long as said Constitution and laws are so interpreted as not to violate due process, it is only in exceptional circumstances that the Supreme Court would feel justified in intervening. ”
