International Brotherhood of Teamsters v. Federal Motor Carrier Safety Administration, No. 18-73488 (9th Cir. 2021)Annotate this Case
The Ninth Circuit denied petitions for review of the FMCSA's determination that federal law preempted California’s meal and rest break rules (MRB rules), as applied to drivers of property-carrying commercial motor vehicles who are subject to the FMCSA's own rest break regulations.
The panel held that the agency's decision reflects a permissible interpretation of the Motor Carrier Safety Act of 1984 and is not arbitrary or capricious. Applying Chevron deference to the agency's interpretation of the statute and the phrase "on commercial motor vehicle safety," the panel held that even assuming petitioners identified a potential ambiguity in the statute, the agency's reading was a permissible one. In this case, the FMCSA reasonably determined that a State law "on commercial motor vehicle safety" is one that "imposes requirements in an area of regulation that is already addressed by a regulation promulgated under [section] 31136." Furthermore, the FMCSA's 2018 preemption decision also reasonably relied on Congress's stated interest in uniformity of regulation.
The panel concluded that the FMCSA permissibly determined that California's MRB rules were State regulations "on commercial motor vehicle safety," so that they were within the agency's preemption authority. The panel also concluded that the FMCSA faithfully interpreted California law in finding that California's rules were "additional to or more stringent than" federal regulations. Finally, the panel concluded that the agency did not act arbitrarily or capriciously in finding that enforcement of the MRB rules "would cause an unreasonable burden on interstate commerce."
