  • Volume: Twenty-five or more similar arbitration demands are filed against the same party.
  • Representation: Consistent or coordinated representation is present across all claims.

Frequently Asked Questions

FAQs

Who can file a mass arbitration case with the AAA?

Consumers, employees, businesses, or individuals can initiate a mass arbitration case with the AAA through their counsel. Mass arbitration involves a large number of parties to an arbitration agreement filing similar claims against the same company or organization.

The AAA has distinct processes in place for consumer mass arbitration and employment/workplace mass arbitration cases. For all other practice areas, the AAA administers non-consumer and non-employment/workplace mass arbitration cases. The AAA has also handled government-led arbitration involving disputes within specific regulated industries.

How are mass arbitration services initiated with the AAA, and what documentation is required?

To initiate a mass arbitration case with the AAA, first email MassArbitration@adr.org to request a secure ShareFile link for document uploads. To complete a mass arbitration filing, parties need to provide the following, in accordance with the Mass Arbitration Supplementary Rules:

  • The case-filing spreadsheet
  • A list of all representatives/counsel
  • Relevant arbitration agreements or court orders
  • A signed affirmation for each case
  • Demand for Arbitration for each individual party

All submitted documents must follow the case identifier format. All documentation should be uploaded using the provided ShareFile link. All submission documents must also be sent to MassArbitration@adr.org and copied to the opposing party.

How are arbitrators selected in mass arbitration cases?

In mass arbitration cases, a process arbitrator is typically selected by the parties early in the case and manages all non-merits issues. A process arbitrator is usually necessary in mass arbitration cases to efficiently handle the complexities that arise in cases involving many parties.

The merit arbitrator(s) — the neutral(s) who render the binding award on an individual case basis — are selected in a separate process. If the parties’ contract does not specify how the arbitrator(s) are to be selected, the selection process is governed by the AAA’s industry-specific arbitration rules. The arbitrator(s) are generally selected through the rank and strike method. In consumer cases, the AAA usually administratively appoints the arbitrator.

How are costs managed in mass arbitration?

Mass arbitration costs vary by practice area, with separate fee schedules for consumer, employment/workplace, and non-consumer and non-employment/workplace mass arbitration cases. Consult the applicable fee schedule to determine current fees for your case. The consumer and employment/workplace mass arbitration fee schedules apply when 25 or more similar demands are filed against or on behalf of the same party or related parties; the non-consumer and non-employment/workplace fee schedule applies when 100 or more similar demands are filed.

Across all practice areas, mass arbitration proceedings are structured to promote efficiency, control costs, and manage high volumes of similar cases. 

Are AAA mass arbitration awards binding?

Yes, generally, AAA awards issued by the merits arbitrator are final and binding. Under applicable federal and state law, arbitration awards can be enforced in court, with limited grounds to overturn — vacate — awards.

How does the AAA manage complex, high-volume mass arbitration cases?

The AAA has established frameworks to handle complex, high-volume cases. Our Mass Arbitration Supplementary Rules help facilitate a streamlined approach to managing large-scale filings. While the AAA’s case management team provides administrative support, a process arbitrator is normally appointed early in mass arbitration cases to handle non-merits matters. A process arbitrator helps navigate the complexities of a mass arbitration filing and serves a distinct function from the merit arbitrator(s), who issue a binding award in the individual cases.
