After AB5 was passed, there were many actions taken by several parties. The most relevant and successful was by the California Trucking Association (CTA), which achieved an injunction against the imposition/enforcement of AB5 for the trucking industry. The CTA argued that AB5 was preempted by federal transportation laws affecting motor carriers.  The Federal Aviation and Administration Authorization Act of 1994 (“FAAAA”), 49 U.S.C. § 14501, et seq., prohibits states from enacting or enforcing laws or regulations that relate to “a price, route or service of a motor carrier . . . with respect to the transportation of property.” The injunction temporarily rules that the FAAAA preempts AB5. The federal court has been asked to review the injunction. Assuming that the California federal courts find that AB 5 is not preempted by the FAAAA, it could set the stage for an appeal to the U.S. Supreme Court, because there is opposing case law from non-California jurisdictions holding that the FAAAA does preempt this type of regulation.
