3 Duer 318 | The Superior Court of New York City | 1854
As there was a conflict in the evidence, the question as to the true nature and terms of the contract of sale was properly submitted to the jury, and as the-cause is now before us only upon the bill of exceptions,» the verdict of the jury must be regarded by us as conclusive. Assuming, as we are bound to do, that the contract between the parties was such as found by the jury, it is certain that the defendant has not paid for the jalap which he purchased the full sum that he agreed to pay, and consequently that the plaintiffs are entitled to a judgment for the balance proved to be due, unless they are estopped from demanding its payment by the settlement between them and the defendant, and the receipt in full which was then given.
The argument on the part of the defendant is that the plaintiffs are concluded by the settlement, since it appears by their own showing that in making it they acted solely under a mistake of law—an erroneous construction of the tariff—and that in no case can a party be entitled to relief upon the ground of such a mistake—since every person is presumed to know the law, and in no case, and for no purpose, is permitted to aver his ignorance.
We think that this doctrine was laid down by the counsel for the defendant in much broader terms than the decisions warrant. It may be admitted, that the law is settled, that.no action will lie for the recovery of money that has been paid,
The only answer given to the claim of the plaintiffs is, that they have received from the defendant the whole sum which they stated to be the price of the jalap, and have given to him a receipt in full. These facts combined, we repeat, constitute the sole defence, since, we apprehend, that, had no such receipt been given, and the payment alone had been proved, the title of the plaintiffs to recover would have been free from doubt, and probably would not have been denied.
It is, therefore, upon the legal operation and effect of this receipt that the controversy wholly turns. It is needless, however, to cite authorities to show that a receipt for money is, in all cases, open to explanation and even contradiction—that it is, in all cases, presumptive merely, and not conclusive evidence, of the payment which it acknowledges. In numerous cases the effect of a receipt, as a bar, has been got rid of by positive evidence of the error which it involved; and we are persuaded that the principle of these decisions is applicable to all cases in which, from a mistake in computation, an error of calculation, a less sum has been demanded and received than was really and justly due. Indeed, an error of calculation, no matter from what cause it arises, may, in all cases, be reasonably considered as a mistake in fact and not in law.
We confess that we are not at all disposed to extend the doctrine, which makes a distinction between different causes of
The judgment for the plaintiffs is affirmed with costs.
