Benjamin Robbins Curtis, Shields v. Barrow — Opinion of the Court
“ It is apparent that, if it were in the power of a circuit court of the United States to make and enforce orders like this, both the article of the constitution respecting the judicial power, and the act of congress conferring jurisdiction on the circuit courts, would be practically disregarded in a most important particular. For in all suits in equity it would only be necessary that a citizen of one State should be found on the side, and a citizen of another State on the other, to enable the court to force into the cause all other persons, either citizens or aliens. No such power exists ”
