There is an Opinion of the Court today in the Health Care Cases (National Federation of Independent Business v. Sibelius). Here is the language from the official report:
CHIEF JUSTICE ROBERTS announced the judgment of the Court and delivered the opinion of the Court with respect to Parts I, II, and III–C, an opinion with respect to Part IV, in which JUSTICE BREYER and JUSTICE KAGAN join, and an opinion with respect to Parts III–A, III–B, and III–D.
Part I is the statement of the case. Part II deals with the Anti Injunction Act. Part II-C is the portion of the opinion that upholds the mandate as a tax.
Justice Ginsburg's opinion, concurring and dissenting was joined as follows:
JUSTICE GINSBURG, with whom JUSTICE SOTOMAYOR joins, and with whom JUSTICE BREYER and JUSTICE KAGAN join as to Parts I, II, III, and IV, concurring in part, concurring in the judgment in part, and dissenting in part.
There was a joint dissenting opinion by Scalia, Kennedy, Thomas, and Alito, and a separate dissent from Thomas.
So there are four opinions altogether. The decision on the constitutionality of the mandate was 5-4 for the government on the tax power issue, but 5-4 against the government on the commerce clause issue.
