Whether an agreement that specifies arbitration before the AAA as the default dispute-resolution method must also specifically mention the AAA Rules to avoid being considered ambiguous about whether the parties intended to apply the AAA Rules

QUESTIONS PRESENTED 1. The parties’ arbitration clause expressly designates the American Arbitration Association (“AAA”) as their default dispute-resolution method. The clause did not also specifically mention the AAA Rules themselves, which, according to the AAA, apply whenever parties select a AAA arbitration. Must an agreement that specifies arbitration before the AAA as the default dispute-resolution method also specifically mention the AAA Rules to avoid being considered ambiguous about whether the parties intended to apply the AAA Rules? 2. Under the plain text of the Federal Arbitration Act, courts—not arbitrators—decide gateway issues, such as whether there is an agreement to arbitrate and what controversies does it cover. Procedural questions, however, are reserved for arbitrators. Is the availability of class arbitration a matter for an arbitrator to decide, or for a court to decide?
