It looks like it was unanimous with Ginsburg & Breyer writing a CONCURRING opinion.
JUSTICE GINSBURG, with whom JUSTICE BREYER joins,concurring.
I join the Court’s opinion and write separately to make the following observation.
Bond, like any other defendant,has a personal right not to be convicted under a constitu-tionally invalid law. See Fallon, As-Applied and Facial Challenges and Third-Party Standing, 113 Harv. L. Rev.1321, 1331–1333 (2000); Monaghan, Overbreadth, 1981Sup. Ct. Rev. 1, 3. See also North Carolina v. Pearce, 395 U. S. 711, 739 (1969) (Black, J., concurring in part and dissenting in part) (“Due process . . . is a guarantee that a man should be tried and convicted only in accordance withvalid laws of the land.”). In this case, Bond argues that the statute under whichshe was charged, 18 U. S. C. §229, exceeds Congress’ enumerated powers and violates the Tenth Amendment. Other defendants might assert that a law exceeds Con-gress’ power because it violates the Ex Post Facto Clause, or the Establishment Clause, or the Due Process Clause. Whatever the claim, success on the merits would requirereversal of the conviction. “An offence created by [anunconstitutional law],” the Court has held, “is not a crime.” Ex parte Siebold, 100 U. S. 371, 376 (1880). “A conviction under [such a law] is not merely erroneous, but is illegal and void, and cannot be a legal cause of impris-onment.” Id., at 376–377. If a law is invalid as applied tothe criminal defendant’s conduct, the defendant is entitled to go free. For this reason, a court has no “prudential” license todecline to consider whether the statute under which the defendant has been charged lacks constitutional applica-tion to her conduct. And that is so even where the consti-tutional provision that would render the conviction void is directed at protecting a party not before the Court. Our decisions concerning criminal laws infected with discrimi-nation are illustrative. The Court must entertain the objection—and reverse the conviction—even if the right toequal treatment resides in someone other than the de-fendant. See Eisenstadt v. Baird, 405 U. S. 438, 452–455 (1972) (reversing conviction for distributing contraceptives because the law banning distribution violated the recipi-ent’s right to equal protection); cf. Craig v. Boren, 429 U. S. 190, 192, 210, and n. 24 (1976) (law penalizing sale of beer to males but not females aged 18 to 20 could not be enforced against vendor). See also Grayned v. City of Rockford, 408 U. S. 104, 107, n. 2 (1972); Welsh v. United States, 398 U. S. 333, 361–362 (1970) (Harlan, J., concur-ring in result) (reversal required even if, going forward, Congress would cure the unequal treatment by extending rather than invalidating the criminal proscription). In short, a law “beyond the power of Congress,” for any reason, is “no law at all.” Nigro v. United States, 276 U. S. 332, 341 (1928).
