The Court issued its much anticipated ruling in DaimlerChrysler Corp. v. Cuno. As many expected, the Cuno plaintiffs’ claim flopped because the plaintiffs had no standing to challenge Ohio’s franchise tax credit. Chief Justice Roberts wrote the opinion, to which all but Justice Ginsburg joined. Justice Ginsburg wrote a separate opinion concurring in part and in the judgment.

Chief Justice Roberts also issued an opinion for a unanimous court, ruling in favor of Mid Atlantic’s equitable relief claim in Sereboff v. Mid Atlantic Medical Services.

Finally, Justice Souter wrote for a nearly unanimous Court in S.D Warren v Maine Board of Environmental Protection. All Justices joined the opinion, but Justice Scalia did not joined as to Part III-C. The ruling held that state approval is needed for a dam, as “a dam does raise a potential for discharge.”

In a rare rejection of a state petitioner with a federal amicus, the Court ruled unanimously that Arkansas may not put a lien on non-medical liability awards to a Medicaid recipient. Perhaps the outcome in ARKANSAS DEPARTMENT OF HEALTH AND HUMAN SERVICES ET AL. v. AHLBORN is most noteworthy for the fact of the Court’s denial of the leagued state and federal government arguments. The Court usually accepts the argument when the two sovereigns align. Justice Stevens wrote.

Justice Alito also wrote today (in another case), which returns the Court to its full complement of nine writing members. The opinions should come in bunches from now until the end of the term. Stay tuned.
