People of the State of Cal. v. Fmcsa
Key claim: The U.S. Court of Appeals for the Ninth Circuit issued an opinion in People of the State of California v. FMCSA on June 4, 2026.
Abstract
U.S. Court of Appeals for the Ninth Circuit opinion decided 2026-06-04.
Why this matters
State-level litigation against FMCSA in the Ninth Circuit signals ongoing federal-state tension over motor carrier safety rulemaking, which can affect how trucking regulations are enforced across western states. Even without a stated holding, tracking the docket helps map the practical scope of federal preemption in commercial vehicle safety.
