A divided three-judge panel of the Ninth Circuit Court of Appeals vacated the January 2020 preliminary injunction against enforcement of Assembly Bill 51 (AB 51), and upheld portions of the law that prohibited employers from making arbitration agreements a condition of employment. As a result of this decision, the Ninth Circuit has resurrected California Labor Code § 432.6, that bars businesses from requiring workers to arbitrate job-related claims. However, the court invalidated portions of AB 51 imposing civil and criminal penalties for mandating arbitration in violation of § 432.6.
