Class arbitration = Gateway issue

“Ordinarily, courts must refrain from interfering with arbitration proceedings. But as our sister circuits have held, and as we now hold today, class arbitration is a ‘gateway’ issue that must be decided by courts, not arbitrators—absent clear and unmistakable language in the arbitration clause to the contrary.” 20/20 Communications, Inc. v. Crawford, No. 1810260 (July 22, 2019).
