Petition of the day

Issue: Whether California’s “Gentry rule” – under which class-action waivers in employment arbitration agreements are invalid if “a class arbitration is likely to be a significantly more effective practical means of vindicating the rights of the affected employees than individual litigation or arbitration,” Gentry v. Superior Court of L.A. County, is preempted by the Federal Arbitration Act in light of this Court’s decisions in AT&T Mobility LLC v. Concepcion and American Express Co. v. Italian Colors Restaurant.
