A federal judge in Sacramento has once again called a stop to enforcement of a California law that would outlaw mandatory arbitration agreements in employment contracts in the state.

U.S. District Judge Kimberly Mueller of the Eastern District of California, who late last year granted a temporary restraining order barring the enforcement of Assembly Bill 51, on Friday granted a preliminary injunction “in full” blocking the state from enforcing the law that she has found preempted by the Federal Arbitration Act. Mueller issued the injunction in a minute order but said that she would lay out her reasoning in a forthcoming written order “in the coming days.”
