SAN FRANCISCO — Kamala Harris gave her time to Consumer Attorneys of California, serving as keynote speaker at the organization’s annual convention last weekend. But California’s attorney general has declined to contribute an amicus curiae brief in a hot-button consumer arbitration case before the Ninth Circuit, leaving one CAOC past president “extremely disappointed.”

A big chunk of the plaintiff bar is mobilizing for Dec. 11 en banc arguments in Kilgore v. KeyBank. The case will determine whether the Federal Arbitration Act preempts a California rule that prohibits the arbitration of claims for broad, public injunctive relief. Public Citizen, the California Employment Law Association and the National Employment Lawyer Association are squaring off as amici curiae on one side with the Chamber of Commerce of the United States and the American Bankers Association on the other.
