Joining several other federal appellate courts including the Fourth and Ninth Circuits , on October 22, 2018 the Seventh Circuit concluded in Herrington v. Waterstone Mortgage Corporation, No. 17-3609 (7th Cir. Oct. 22, 2018) that the arbitrability of a class claim is one for the court to decide, not the arbitrator. In so doing, the court placed in jeopardy a $10 million arbitration award in a wage-hour case.
