American Trucking Assns., Inc. v. Los Angeles

Background

A national trucking trade group sued the Port and City of Los Angeles over a Clean Truck Program that requires drayage trucking companies to display placards with a reporting phone number and to submit off-street parking plans. The Port put those rules into a standard concession agreement and backed compliance by amending a municipal tariff that forbids terminal operators from serving trucks not registered under the contract, with misdemeanor penalties.

Reasoning

The central question was whether a federal statute (section 14501(c)(1) of the FAAAA) preempts local requirements that have the "force and effect of law." The Court held that the placard and parking provisions, though in contracts, were enforced through government power and criminal penalties and therefore acted like laws; as a result, those provisions are preempted. The Court rejected the Port's argument that its motives and proprietary aims saved the rules from preemption.

Real world impact

Trucking companies and the terminal operators at the Port can no longer be required, under these specific contract clauses, to post the designated placards or to file off-street parking plans because federal law preempts them. Two other contract requirements (financial-capacity and maintenance) were left standing, and the Court refused to decide now whether the Port may use its penalty clause to suspend or revoke carrier access; the case is remanded for further proceedings.

Dissents or concurrances

Justice Thomas joined the judgment but warned that the federal preemption statute may potentially raise constitutional questions about Congress's power to regulate intrastate matters.
