On February 15, 2023, in Chamber of Commerce of the United States of America et al. v. Bonta et al., a panel of the U.S. Court of Appeals for the Ninth Circuit held that the Federal Arbitration Act (“FAA”) preempts a state rule that discriminates against the formation of an arbitration agreement, even if that agreement is ultimately enforceable. The law at issue, California Assembly Bill 51 (“AB 51”), made it a criminal offense for an employer to require an existing employee or an applicant for employment to consent to arbitrate specified claims as a condition of employment.  The court concluded that because the FAA preempts AB 51, AB 51 cannot be enforced.
