United States v. Rock Island Motor Transit Co.

Background

A railroad-owned trucking company called Rock Island Motor Transit and the Interstate Commerce Commission disputed limits on trucking routes the carrier acquired in 1941 and 1944. The carrier operated truck routes largely alongside its parent railroad. The 1941 certificate contained a reservation allowing the Commission to impose further limits to keep the motor service "auxiliary or supplementary" to train service. After reopening the dockets, the Commission ordered five conditions restricting where and how the carrier could operate. The carrier sued and a three-judge district court enjoined enforcement of those conditions.

Reasoning

The Court addressed whether the Commission had statutory power to impose and enforce such conditions after approving the acquisitions. It reviewed the Transportation Policy and the statutes governing certificates and acquisitions, and concluded the Commission may require rail-affiliated motor carriers to serve only in an auxiliary or supplemental role when justified to preserve the advantages of each transport mode. The Court held the 1941 reservation permitted the Commission to add limits and that approval orders short of a final certificate did not bar the Commission from framing final certificates with such conditions. The Court reversed the district court and directed dismissal of the complaint.

Real world impact

The decision confirms that federal regulators can restrict railroad-owned trucking operations to support rail service rather than allow broad, independent truck competition. Affected carriers may face limits on routes, billing practices, and through-traffic previously relied on for revenue. The ruling enforces the Commission’s role in balancing rail and truck transportation under national policy.

Dissents or concurrances

Four Justices dissented, arguing the Commission had effectively revoked parts of certificates in a manner not authorized by the statute, and would have affirmed the district court.
