The Court has decided the latest in a series of important cases interpreting the reach of the Federal Arbitration Act (FAA), 9 U. S. C. §§ 1 et seq.
On March 31, in Badgerow v. Walters, by an 8-1 majority (opinion written by Justice Kagan, and a lone dissent by Justice Breyer), the Court reversed an order of the Fifth Circuit and held that the federal courts do not have authority to “look through” an arbitration dispute for a federal question that would establish jurisdiction to confirm or deny an arbitral award.
