The Court's decision to hear Oxford comes less than a month after it also granted certiorari in American Express Company vs. Italian Colors Restaurant, No. 12-133 (" AMEX ") to address the following question: "Whether the Federal Arbitration Act permits courts, invoking the 'federal substantive law of arbitrability,' to invalidate arbitration agreements on the ground that they do not permit class arbitration of a federal-law claim." (Previously blogged at Supreme Court to Address Enforceability of Arbitration Agreements and Class Action Waivers Yet Again ). The Supreme Court has also taken on cases involving class action waivers and arbitration agreements in each of the last three years. See, e.g., CompuCredit Corp. v. Greenwood, 132 S. Ct. 665 (2012) (holding that an arbitration agreement could be enforced in a case involving claims under the federal Credit Repair Organizations Act (CROA), because the CROA is silent on whether arbitration is permissible); AT&T Mobility LLC v.
