Great Northern Railway Co. v. Cahill

Background

A local firm (Cahill and Redman) asked the South Dakota railroad commission to order the Great Northern Railway to install and maintain a cattle-weighing scale at Albee station. The firm said no other weighing was available, many buyers used scales for trading, and the scale would help shippers avoid under-loading cars. The commission found a public necessity and ordered the railway to install a scale. The state courts disagreed: an intermediate court held the railway had no duty to provide scales, the state supreme court later reversed and upheld the commission’s order, and the United States Supreme Court was asked to review that ruling.

Reasoning

The Court had to decide whether a railroad can be forced to install a cattle scale as part of its transportation duties. Relying on a prior decision about similar railroad orders in Minnesota, the Court explained that scales are not part of the carrier’s core duty to transport goods and are mainly used by buyers for trading. Because forcing the railroad to install a scale would impose a property burden beyond its transportation responsibilities and would be arbitrary without clear public necessity, the Court concluded the Minnesota ruling controlled and reversed the state court’s decision.

Real world impact

The ruling limits state agencies’ ability to require railroads to add nontransport facilities like weighing scales unless a compelling public necessity is shown. Railroads are protected from compelled property expenditures where the facility serves mainly local trade. The case was sent back for further proceedings consistent with this decision.
