Vincent and Liza Concepcion purchased AT&T Mobility cell phones that were advertised as free with service, but they were charged $30.22 in sales tax based on the phones' full retail value. Their customer agreement contained an arbitration clause requiring bilateral arbitration of disputes and expressly prohibiting class proceedings in arbitration or court. The clause included consumer-friendly features: AT&T would pay all arbitration costs for nonfrivolous claims; arbitration could occur in the consumer's county; small claims court remained available; and if the consumer received an award greater than AT&T's last written settlement offer, AT&T would pay a minimum of $7,500 plus double the consumer's reasonable attorney's fees. The Concepcions filed suit alleging false advertising and fraud under California law. AT&T moved to compel individual arbitration. The federal district court, applying California's Discover Bank rule (which deemed class-arbitration waivers in certain consumer adhesion contracts unconscionable), denied the motion to compel. The Ninth Circuit affirmed, holding that the Discover Bank rule was a generally applicable contract defense preserved by the FAA's saving clause and therefore not preempted. The Supreme Court granted certiorari.
Does the Federal Arbitration Act preempt California's Discover Bank rule, which classifies most class-arbitration waivers in consumer adhesion contracts as unconscionable and thus unenforceable?
Section 2 of the Federal Arbitration Act makes arbitration agreements valid, irrevocable, and enforceable, save upon such grounds as exist at law or in equity for the revocation of any contract. While generally applicable contract defenses (e.g., fraud, duress, unconscionability) may invalidate arbitration agreements, state-law rules are preempted when they stand as an obstacle to the accomplishment and execution of the FAA's purposes and objectives, including enforcement of arbitration agreements according to their terms and preservation of arbitration's fundamental attributes—informality, speed, and efficiency. States may not require procedures incompatible with arbitration (such as classwide arbitration) absent the parties' consent.
Yes. The FAA preempts California's Discover Bank rule. Arbitration agreements must be enforced according to their terms, including provisions requiring individualized arbitration and waiving class proceedings.
The Court, in an opinion by Justice Scalia, emphasized that the FAA embodies a national policy favoring arbitration and requires courts to place arbitration agreements on equal footing with other contracts and enforce them according to their terms. The FAA's saving clause preserves generally applicable contract defenses, but it does not sanction state rules that, in application, disfavor arbitration or interfere with its fundamental attributes. The Discover Bank rule—categorically deeming class-arbitration waivers unconscionable in many consumer adhesion contracts—operates as a requirement that arbitration be available on a classwide basis. Imposing class procedures on arbitration fundamentally transforms its nature: it increases formality, complexity, and cost; requires procedural safeguards akin to Rule 23; compromises the speed and informality that arbitration is meant to ensure; and dramatically raises the stakes for defendants due to aggregation, with limited judicial review of arbitral awards. These effects are incompatible with the FAA's objectives. Citing Stolt-Nielsen S.A. v. AnimalFeeds Int'l Corp., the Court reiterated that parties cannot be compelled to submit to class arbitration absent an agreement to do so. Although the Concepcions' arbitration clause contained pro-consumer provisions (including AT&T's cost-shifting and $7,500 minimum recovery premium), both the district court and Ninth Circuit nevertheless invalidated the class waiver under Discover Bank. The Supreme Court held that California's rule is preempted because it stands as an obstacle to the FAA's purpose of promoting streamlined proceedings and enforcing arbitration agreements as written. The dissent's concern that class procedures are necessary to vindicate small-value claims could not justify imposing class arbitration, as the FAA does not permit states to condition enforcement of arbitration agreements on the availability of class mechanisms.
Concepcion dramatically expanded the enforceability of class-arbitration waivers, catalyzing their widespread use in consumer and employment agreements. It restricts states from using generally framed doctrines like unconscionability to impose class procedures on arbitration, solidifying federal preemption where such doctrines undercut arbitration's core attributes. The decision set the stage for subsequent Supreme Court rulings that reinforced individualized arbitration (e.g., American Express v. Italian Colors, Epic Systems v. Lewis, Lamps Plus v. Varela) and narrowed pathways for aggregate dispute resolution absent explicit agreement. For law students, Concepcion is a cornerstone for understanding the FAA's saving clause, obstacle preemption, and the modern arbitration regime's profound procedural and substantive consequences.
AT&T Mobility v. Concepcion reshaped the balance between state contract law and federal arbitration policy by holding that state rules invalidating class waivers are preempted when they obstruct arbitration's defining features. It requires courts to enforce arbitration agreements as written, including bilateral-only provisions, and limits the use of generally applicable contract doctrines to indirectly impose class procedures.
