Boyce Motor Lines, Inc. v. United States

1952-01-28

Headline: Court upholds federal safety regulation and allows criminal charges for knowingly sending hazardous liquid through tunnels, making it easier to prosecute carriers that violate route-avoidance rules and protecting public safety.

Holding: The Court held that the Commission’s regulation is not unconstitutionally vague and that the indictment alleging knowing violations for routing hazardous cargo through the tunnel should be reinstated and tried.

Real World Impact:

Allows criminal trials against carriers who knowingly send hazardous cargo through tunnels.
Affirms agency route-avoidance rules made after industry study.
Requires proof of a commercially practicable safer route and knowing violation.

Summary

Background

A trucking company is accused of knowingly sending a truck carrying carbon bisulphide, a dangerous and inflammable liquid, through the Holland Tunnel on three trips from Cascade Mills to Brooklyn. On the third trip the load exploded and about sixty people were injured. The company was indicted for violating an Interstate Commerce Commission regulation under 18 U.S.C. § 835 that tells drivers to avoid, so far as practicable and where feasible by prearrangement, congested thoroughfares, places where crowds gather, streetcar tracks, tunnels, viaducts, and dangerous crossings. The district court dismissed the counts as unconstitutionally vague; the Court of Appeals reversed and the Supreme Court agreed to review.

Reasoning

The Supreme Court held that the regulation is not so vague as to be invalid. The majority relied on prior decisions saying ordinary terms can be understood by common experience, noted the regulation’s long rulemaking history and industry participation, and emphasized that the statute punishes only knowing violations. Because a conviction would require proof of a commercially practicable, appreciably safer route and knowledge or willful failure to check alternatives, the rule supplies a workable standard for trial. The Court affirmed the appeals court and directed reinstatement of the challenged counts.

Real world impact

The ruling lets criminal prosecution go forward against carriers accused of deliberately sending hazardous cargo through places the regulation aims to avoid. It preserves agency-made route-avoidance rules adopted after study and makes clear defendants can be convicted only if the government proves a knowing violation. This decision resolves a motion to dismiss; the final result will depend on trial proof.

Dissents or concurrances

Justice Jackson, joined by Justices Black and Frankfurter, dissented, arguing the regulation lacks precise standards, could leave carriers with no practicable alternative, and that vagueness risks unfair prosecutions and needs clearer rules.
