Viking River Cruises, Inc. v. Moriana

Holding: The Federal Arbitration Act preempts a rule of California law that invalidates contractual waivers of the right to assert representative claims under PAGA " the California Private Attorneys General Act " insofar as that rule precludes division of PAGA actions into individual and non-individual claims through an agreement to arbitrate.
