AT&T Mobility LLC v. Concepcion

Background

A mobile-phone company (AT&T) used a customer contract that required arbitration for disputes and barred classwide arbitration. Two customers (the Concepcions) were charged sales tax on phones advertised as free and joined a larger class lawsuit. The lower courts applied California’s Discover Bank rule and held the class-waiver in arbitration agreements unconscionable, so the district court refused to force arbitration and the Ninth Circuit affirmed. The case reached the Supreme Court to decide whether federal law overrides that California rule.

Reasoning

The Court framed the question as whether the Federal Arbitration Act (FAA) prevents states from conditioning arbitration agreements on allowing classwide procedures. The majority said the FAA embodies a national policy to enforce arbitration agreements as written, and that California’s rule conflicts with that policy because it effectively requires class arbitration in many consumer cases. The Court explained class arbitration changes arbitration’s informal, faster character and raises procedural risks, so the California rule stands as an obstacle to the FAA. The Supreme Court reversed the Ninth Circuit and held the Discover Bank rule is preempted.

Real world impact

The ruling means companies can enforce contract terms that bar class arbitration in many consumer agreements, making classwide arbitration less available. States remain free to regulate contracts in ways that do not conflict with the FAA, for example by highlighting waiver terms. The decision removes a California-based limit on enforcing arbitration clauses and returns disputes to the terms parties agreed to.

Dissents or concurrances

A concurrence agreed on result but for narrower textual reasons. A four-Justice dissent argued California’s rule treats arbitration and courts the same and should not be preempted, stressing state authority and consumer protections.
