United States v. New River Co.

Background

A group of coal operators who ran mines served by two railroads (called "joint mines") sued two competing railroads, the United States, and the Interstate Commerce Commission (ICC). The dispute arose over Rule 4, a car distribution rule that limited a joint mine’s combined daily orders to its gross daily rating. Carriers had tried a different "150 percent" approach that allowed larger combined orders; after initial ICC support for that approach, the full Commission reversed and approved Rule 4, and the carriers announced they would return to Rule 4, prompting the mine operators to file suit in federal court.

Reasoning

The Court first held that the federal district court could review the ICC’s order. On the merits, the majority concluded that the Commission’s decision approving Rule 4 was not arbitrary, unreasonable, or an unauthorized exercise of power over car distribution. The Court explained that the Commission reasonably allocated cars during shortages by using gross daily ratings for joint mines, and the courts should not substitute their judgment for the Commission when the agency acted within its statutory authority. The Supreme Court therefore reversed the lower court’s decree that had set aside the ICC order.

Real world impact

The decision lets rail carriers apply Rule 4, so joint mines cannot automatically combine full entitlements from both railroads beyond their gross daily rating during shortages. Local mines served by a single carrier retain their pro rata shares of that carrier’s available cars. Because the Supreme Court reversed the lower court, the ICC’s ruling and Rule 4 remain in effect as the governing distribution rule.

Dissents or concurrances

Justice McKenna dissented, arguing the rule takes an important advantage away from joint‑mine owners and therefore unfairly deprives them of property.
