In another big decision this morning, the Supreme Court held unanimously against class action plaintiffs seeking to sue Wal-Mart for gender discrimination in Wal-Mart v. Dukes. While the Court split 5-4 over the scope of the decision, the Court was unanimous that the class should not have been certified. This outcome is not-so surprising given the oral argument, at which most of the justices expressed concern about the class certification. Justice Scalia wrote the opinion for the Court. Justice Ginsburg wrote a partial dissent.
