Edward Douglass White, Fritzlen v. Boatmen's Bank — Opinion of the Court
“ We observe, however, that, under the case made, as the bank was not an indispensable party to the suit of Weldon to foreclose, the mere fact that the bank was by him joined as a defendant along with Fritzlen cannot be held to operate to prevent the application of the rule of separable controversy, and that, from its application, we think it quite clear that the validity of the bank's mortgage, assailed as it was under the circumstances of the case, was a separable controversy, with Weldon and Fritzlen on one side and the bank on the other, and it was therefore rightly the subject of removal. ”
