Melville Fuller,
Ex parte Ward Fuller — Opinion of the Court
“ If it does not appear at the outset that the suit is one of which the circuit court, at the time its jurisdiction is invoked, could properly take cognizance, the suit must be dismissed; and lack of jurisdiction cannot be supplied by anything set up by way of defense. And so, when jurisdiction originally depends on diverse citizenship, the decree of the circuit court of appeals is final, though another ground of jurisdiction may be developed in the course of the proceedings. ”
