Today Justice Scalia delivered the opinion in Wal-Mart v. Dukes, the largest ever class-action suit. Brought by female employees of the retail giant it accused Wal-Mart of sex discrimination in pay and promotion. Not surprisingly Wal-Mart won.
The other opinion on my watch list to come down today, American Electric Power Co. v. Conn., did not get as much attention. In an opinion written by Justice Ginsburg the Court said that the regulation of greenhouse gases is the job of the EPA, and that States cannot make an end run around the Clean Air Act by filling a "public nuisance" claim in federal court.
