Southern Pacific Co. v. United States

Background

The case involves the Southern Pacific Company, a railroad that operated a continuous line from San Francisco to Portland under a lease. Parts of that line were built under federal laws that required the railroad to transport Government people and property, and one segment (north of Roseville Junction) was a free-haul for the United States. Between August 1897 and March 1902 the railroad carried United States shipments in one continuous movement over both the free segment and the paid segment. The company billed nothing for the free segment and charged the higher local rate for the paid segment; government accounting officers instead treated the movement as a through shipment and applied the lower published through rate across the whole trip, deducting the difference and prompting the railroad to sue to recover the amounts withheld.

Reasoning

The key question was whether a continuous government shipment that passes over both free and paid portions can be split and charged higher local rates for parts of the journey. The Court said the character of the movement — whether it is a through shipment — governs which published rate applies, not the carrier’s attempt to divide charges to increase pay. Because the published schedules included a through rate from San Francisco to Portland, the United States was entitled to that rate for its through shipments. The Court rejected the railroad’s theory that compensation rules could create an artificial break at Roseville Junction and affirmed the lower court’s judgment against the railroad.

Real world impact

Carriers transporting federal personnel or supplies in continuous movements must allow the Government to use the published through rate, preventing railroads from splitting trips to collect higher local charges. This ruling ensures the Government benefits from lower published through tariffs for continuous shipments under the statutes at issue.
