Today the Supreme Court released its opinion in Shady Grove Orthopedic v. Allstate Insurance. The case concerns whether state law can preclude a federal court from considering a class-action when the federal court is exercising diversity jurisdiction over a case that primarily raises state law claims. I’m sure others will have plenty to say on the import of the Court’s holding. For now I just thought I’d note the interesting line-up: Justice Scalia announced the judgment of the Court. His opinion was joined (in whole or in part) by the Chief Justice and Justices Stevens, Thomas, and Sotomayor. Justice Stevens wrote an opinion concurring in part and concurring in the judgment. Justice Ginsburg dissented, joined by Justices Kennedy, Breyer, and Alito.
