In Adams, Postmates, a delivery platform company, sued over 10,000 individual couriers seeking a declaratory judgment that the arbitration demands would force a de facto class-arbitration procedure in violation of their arbitration agreement and that California SB 707 (which imposes sanctions on companies that do not pay arbitration filing fees in time) was preempted. The court found that SB 707 was not preempted and compelled Postmates to arbitrate the claims.
