delivered the opinion of the court.
No exception can be considered here which was not taken in the court below.*
The point relied upon to reverse the judgment is not that the copartners of the plaintiff below could not assign their interests in the original contract so as to vest in him the right to sue in his own name alone, but that one of the assignors was, at the time of the commencement of the action, a citizen and resident of the same State with the defendant, and that hence the Circuit Court had no jurisdiction.
To this there are two answers.
The objection to jurisdiction upon the ground of citizenship, in actions at law, can only be made by a plea in abatement. After the general issue, it is too late. It cannot be raised at the trial upon the merits.† If a plea in abatement be filed with the general issue, the latter waives the former.‡ Where a plea in abatement is relied upon, the burden of proof rests upon the defendant.§ In equity, the defence must be presented by plea or demurrer, and not by answer.ǁ The court below properly overruled the motion.
We thiuk, also, that a new contract between the plaintiff
Judgment aeeirmed with costs.
