Interstate Commerce Commission v. Mechling

Background

Barge companies and the Secretary of Agriculture challenged an Interstate Commerce Commission order that would allow eastern railroads to charge a 3-cent higher reshipping rate for grain brought to Chicago by barge than for grain arriving by rail or lake. Historically the Chicago-to-east reshipping rate was the same whether grain arrived by barge, lake, or rail, and barges had a clear cost advantage that shifted much traffic to water. The railroads sought higher rates for ex-barge shipments, the Commission approved a limited increase, and barge carriers sued to stop it.

Reasoning

The central question was whether the Commission could permit the higher ex-barge reshipping charge without specific evidence that the eastern railroads actually incurred greater costs handling ex-barge grain. The Court held Congress intended the Transportation Act of 1940 to preserve the inherent cost advantages of water transport. The Commission’s broad averages and general findings did not show that eastern railroads’ east-of-Chicago costs for ex-barge grain exceeded those for ex-rail or ex-lake grain. Because the statutory provisions forbade discriminatory rates that would erode barge advantages, the Court affirmed the injunction against the 3-cent increase.

Real world impact

The ruling protects barge operators and shippers from a railroad rate increase that would have reduced the cost benefit of water transport. It prevents rail carriers from using through-rate adjustments to neutralize barges’ lower inbound costs unless precise cost evidence supports the change. The decision also limits how the Commission may adjust through rates when those changes would undermine Congress’s protection of cheaper water transportation.

Dissents or concurrances

Justice Frankfurter would have sustained the Commission’s order based on its findings; Justice Jackson dissented, arguing the Court improperly displaced statutory discretion given to the Commission.
