Notable 5-4 SCOTUS split in ruling to limit civil penalties of Bank Secrecy Act

Certain types of Supreme Court cases involve issues that can make it relatively easy to predict how nearly every Supreme Court Justice will vote.  But so-called "white-collar" cases are often not the predictable type, and today's Supreme Court ruling in Bittner v. United States, No. 21-1195 (Feb. 28, 2023) (available here), is a notable example of this reality.  The case involved the proper accounting for civil penalties for non-willful violations of the Bank Secrecy Act, and the individual prevails against the federal government through this notable voting pattern: 

GORSUCH, J., announced the judgment of the Court, and delivered the opinion of the Court except as to Part II–C. JACKSON, J., joined that opinion in full, and ROBERTS, C. J., and ALITO and KAVANAUGH, JJ., joined except for Part II–C. BARRETT, J., filed a dissenting opinion, in which THOMAS, SOTOMAYOR, and KAGAN, JJ., joined.

Criminal justice fans should be a bit disappointed by the decision by three Justices to not join Part II-C of Justice Gorsuch's opinion. That section has these notable things to say about the rule of lenity:

Under the rule of lenity, this Court has long held, statutes imposing penalties are to be “construed strictly” against the government and in favor of individuals.  Commissioner v. Acker, 361 U.S. 87, 91 (1959)....

The rule of lenity is not shackled to the Internal Revenue Code or any other chapter of federal statutory law. Instead, as Acker acknowledged, “[t]he law is settled that penal statutes are to be construed strictly,” and an individual “is not to be subjected to a penalty unless the words of the statute plainly impose it.” 361 U. S., at 91 (internal quotation marks omitted and emphasis added).  Notably, too, Acker cited to and relied on cases applying this same principle to penalty provisions under a wide array of statutes, including the Communications Act of 1934, a bankruptcy law, and the National Banking Act.  See ibid....

[T]he rule exists in part to protect the Due Process Clause’s promise that “a fair warning should be given to the world in language that the common world will understand, of what the law intends to do if a certain line is passed.” McBoyle v. United States, 283 U.S. 25, 27 (1931).

If this section of the Bittner opinion carried the Court, I suspect this case might end up cited in more than a few criminal statutory interpretation cases. Maybe it still will be, but I suspect this ruling will end up of more interest to bankers than to criminal lawyers.
