Smithers v. Smith — Opinion of the Court
“ In short, the fact of a valid defense to a cause of action, although apparent on the face of the petition, does not diminish the amount that is claimed, nor determine what is the matter in dispute; for who can say in advance that that defense will be presented by the defendant, or, if presented, sustained by the court?'Nevertheless, however stringent and farreaching the rule may be that it is the plaintiff's statement of his case which governs in determining the jurisdiction, it does not exclude the power of the court to protect itself against fraud. ”
