Melville Fuller,
Pacific Exp. Company v. Malin…
“ The present alleged counter-claim is founded on the converse of the same cause of action as that counted on by the plaintiffs, and, inasmuch as the verdict and judgment determined that the defendant had been guilty of negligence, and that the plaintiffs had not, it may be assumed that the defendant suffered no injury through the action of the court in sustaining the exception to it. ”
