Pennsylvania Railroad v. Puritan Coal Mining Co.

Background

A coal shipper called the Puritan Company sued an interstate railroad for damages after it failed to supply cars for coal shipments during the 1902 anthracite strike. The shipper relied on the railroad’s own rule that, during shortages, cars should be allotted by mine capacity. A state trial court and the Supreme Court of Pennsylvania found for the Puritan Company, and the railroad appealed to the United States Supreme Court, arguing that the federal regulatory agency (the Commission) or federal courts, not state courts, must decide these disputes.

Reasoning

The Court examined the Commerce Act provisions that let a shipper either complain to the federal Commission or sue in federal court. It also considered a proviso preserving existing state remedies. The justices drew a key distinction between two kinds of claims: (1) attacks on the allocation rule itself, which require the Commission’s judgment about the rule’s fairness, and (2) claims that a facially fair rule was unequally applied to a particular shipper, which are factual disputes for courts. Because Puritan’s case alleged unequal enforcement of the carrier’s own rule rather than a challenge to the rule’s validity, the Court held state courts could hear the damages claim and affirmed the state judgment.

Real world impact

Shippers who say a carrier failed to follow its own allocation rules can sue for damages in state court. But if a shipper attacks the fairness of the allocation rule itself, the federal agency or federal courts must resolve that issue. The decision preserves concurrent state-court remedies for enforcement claims while reserving rule‑making disputes for the federal regulator.
