The dissent discounts the relevance of the principle here, on grounds that this case involves the scope of a statutory exception to liability, rather than a provision “delineat[ing] a category of prohibited conduct.”
Post, at 625, 176 L. Ed. 2d, at 554 (opinion of Kennedy, J.). That is a distinction without a difference, as our precedents have made clear for more than 175 years.
Barlow involved a statute providing for forfeiture of any goods entered “by a false denomination” in the office of a customs collector “for the benefit of drawback or bounty upon the exportation”; the statute included, however, an exception under which “said forfeiture shall not be incurred, if it shall be made appear . . . that such false denomination . . . happened by mistake or accident, and not from any intention to defraud the revenue.” 7 Pet., at 406, 8 L. Ed. 728; see also Act of Mar. 2, 1799, § 84, 1 Stat. 694. The Court concluded that the shipment at issue, entered as “refined sugars,” was mislabeled under the prevailing meaning of that term and thus was subject to forfeiture “unless the [petitioner] c[ould] bring himself within the exceptio [n].” 7 Pet., at 409-410, 8 L. Ed. 728. As there had been no “accident” or “mistake” of fact, the “only mistake, if there ha[d] been any, [wa]s a mistake of law.”
Id., at 410-411, 8 L. Ed. 728. The Court observed that the shipper’s conduct, even if “entirely compatible with good faith, [wa]s not wholly free from the suspicion of an intention to overreach ... by passing off, as refined sugars, what he well knew were not admitted to be such.”
Id., at 411, 8 L. Ed. 728. But the Court declined to resolve the case on the ground of the shipper’s intent, instead invoking the “common maxim, familiar to all minds, that ignorance of the law will not excuse any person, either civilly or criminally.”
Ibid. Notwithstanding the existence of a statutory exception—which did not expressly exclude legal errors from the category of “mistake [s]” made without “intention to defraud”—the Court saw “not the least reason to suppose that the legislature, in this enactment, had any intention to supersede the common principle.”
Ibid. The dissent implies
Barlow is too old to be relevant.
Post, at 626, 176 L. Ed. 2d, at 555. But at least in the context of
stare decisis, this Court has suggested precedents tend to gain, not lose, respect with age. See
Montejo v.
Louisiana, 556 U.S. 778, 792-793, 129 S. Ct. 2079, 173 L. Ed. 2d 955 (2009). In any event, Justice Story’s opinion for a unanimous Court in
Barlow is hardly a relic. As recently as 1994 this Court cited it for the “venerable principle” that ignorance of the law generally is no defense.
Ratzlaf v. United States, 510 U.S. 135, 149, 114 S. Ct. 655, 126 L. Ed. 2d 615; see also
Cheek v.
United States, 498 U.S. 192, 199, 111 S. Ct. 604, 112 L. Ed. 2d 617 (1991) (citing
Barlow for a similar proposition).
