McDonald v. Thompson
Headline: Court affirmed that the federal Motor Carrier Act’s 'bona fide operation' exemption does not protect a motor carrier who operates in defiance of state truck laws, allowing Texas to enforce its licensing ban against him.
Holding:
- Lets states enforce motor-carrier licensing against operators without state permission.
- Prevents carriers from invoking the federal proviso when defying state law.
- Leaves unresolved whether federal law overrides state rules in other cases.
Summary
Background
A motor carrier who had been using Texas public highways to haul goods across state lines sued the members of the Texas Railroad Commission and its enforcement officers in the federal court for the northern district of Texas to stop enforcement of the state Motor Truck Law. He applied to the Texas commission in May 1934 and was denied a state certificate on July 14, 1934; a Texas court briefly enjoined the Commission but the state court of civil appeals later dissolved that injunction on January 8, 1936. The carrier also applied to the Interstate Commerce Commission under the 1935 federal Motor Carrier Act, claiming he was in 'bona fide operation' before June 1, 1935; that federal application remained pending when he sued. The district court entered a permanent injunction protecting his interstate operations, the circuit court of appeals reversed and ordered dismissal, and the Supreme Court granted review.
Reasoning
The Court asked whether the carrier’s activities qualified as being 'in bona fide operation' under the federal Act’s proviso. It explained the Act is remedial and that exemptions should be read to include only carriers plainly within their terms. The Court said 'bona fide' implies absence of evasion and actual, not merely potential or simulated, service, and rejected reading the phrase to mean only physical operation. Because the carrier had been operating without state authority and in defiance of the Texas commission’s denial, the Court concluded the proviso did not protect him and affirmed the judgment. The Court expressly declined to decide more broadly whether or when the federal Act supersedes state law.
Real world impact
The ruling allows states to enforce motor-carrier licensing and safety rules against operators who run routes without state permission, and it prevents carriers who defy state law from invoking the federal provisional exemption. Because the Court did not address broader preemption questions, other disputes about when federal transportation law overrides state regulation remain open.
