Mass arbitration is a type of legal action in which a group of claims, or “demands,” is filed against a common party and in which all parties’ representation is coordinated across cases. While similar to a class action lawsuit, a mass arbitration proceeding takes place out of court, and each claim is settled individually based on its merits. In recent years, mass arbitrations have emerged as a response to mandatory arbitration clauses with class-action waivers, becoming more common as corporations seek new ways to resolve disputes with consumers and employees.
