Facts
- Illinois enacted a statute penalizing railroads for charging the same or higher rates for a shorter haul than for a longer haul over the same line for the same class of freight.
- Wabash, a multistate railroad, carried freight under through arrangements from Illinois points (including Peoria and Gilman) to New York City.
- On the same day, Wabash charged a lower through rate from Peoria to New York than from Gilman to New York, although the freight was of the same class and moved over the same line.
- The Peoria shipment traveled farther within Illinois than the Gilman shipment, yet cost less overall.
- Illinois prosecuted Wabash for “unjust discrimination” based on the rate differential for these interstate shipments.
Issues
- Whether a state may apply a long- and short-haul anti-discrimination rate statute to a continuous shipment moving from points within the state to a destination in another state.
- Whether applying such a statute to through interstate rates constitutes a direct regulation of interstate commerce in violation of the Commerce Clause.
- Whether state power to regulate in the absence of congressional legislation extends to prescribing or constraining charges for the in-state portion of an interstate transportation contract.
Decision
- The U.S. Supreme Court reversed the judgment against Wabash.
- Transportation under a single continuous interstate contract is “commerce among the states,” including the portion of the movement occurring within the originating state.
- Illinois could not apply its long- and short-haul statute to through shipments from Illinois to New York because it imposed a direct burden on interstate commerce.
- The Court recognized that states may regulate rates for transportation that begins and ends within the state and is not connected to carriage outside the state.
Legal Principles
- A continuous shipment from one state to another is interstate commerce throughout the journey, even while physically within a single state.
- Direct state regulation of interstate transportation rates is unconstitutional; authority to regulate interstate commerce is vested in Congress.
- States may regulate intrastate transportation rates when the movement is wholly within the state and not part of an interstate transaction.
- Prior decisions upholding state regulation of rail-related charges were not read to authorize state control of rate structures governing interstate carriage.
Conclusion
The Court held that Illinois’s long- and short-haul rate statute, as applied to through interstate shipments, was an invalid direct regulation of interstate commerce; only Congress may regulate interstate railroad rate structures, while states retain authority over purely intrastate transportation.
