Joseph P. Bradley, Doyle v. Continental Insurance Company…
“ If a State is unwise enough to legislate the one, it has no constitutional power to legislate the other. The citizens of the United States, whether as individuals or associations, corporate or incorporate, have a constitutional right, in proper cases, to resort to the courts of the United States. Any agreement, stipulation, or State law precluding them from this right is absolutely void,-just as void as would be an agreement not to resort to the State courts for redress of wrongs, or defence of unjust actions ”
