Morrison Waite

“ The construction of the act is by no means free from doubt, but on full consideration we are of opinion that the requirement of the old law, that the necessary citizenship should exist when the suit was brought, was not abolished. We cannot believe it was intended to allow a party to deprive a state court of the jurisdiction it has once rightfully acquired over him by changing his citizenship after a suit is begun, and that would be the effect of the law if the right of removal is made to depend only on the citizenship existing at the time a removal is applied for. ”
