U.S. Supreme Court KNOX v. JONES, 2 U.S. 193 (1792)
2 U.S. 193 (Dall.)
Knox et al.
Supreme Court of Pennsylvania
September Term, 1792
This was an action on the case for goods sold and delivered; and the only question agitated upon the trial, was whether the plaintiff was entitled to recover interest? It was proved, that at the time of the sale, the defendant was informed, that it was the course of the trade to give six months credit; or, if cash was paid, to discount five per cent; but that punctuality, and not interest, was the object of the plaintiffs.
By the Court: The established course of the plaintiffs' trade is proved; and, also, the knowledge of the defendant.
It appears, therefore, to be a part of their contract, that interest should commence, at the expiration of the six months credit.
Verdict accordingly. Footnotes
