Simpson v. Shepard

Background

Stockholders of three railroad companies (Northern Pacific, Great Northern, and Minneapolis & St. Louis) sued to stop Minnesota from enforcing two commission orders and two state laws that set maximum intrastate freight and passenger charges. The suits challenged class rates set by a 1906 commission order, a two‑cent‑a‑mile passenger law, a 1907 commodity rate law, and a supplemental commission order. Federal trial findings and a master’s report had supported the stockholders and a federal court enjoined the state rates in most respects.

Reasoning

The Court examined whether Minnesota’s rules, which by their terms covered only transportation wholly inside the State, nonetheless imposed a direct burden on interstate commerce or conflicted with the federal law regulating rail traffic. Relying on constitutional principles and the federal statute’s explicit exclusion of purely intrastate transportation, the Court held that States retain authority to prescribe reasonable maximum rates for internal transportation unless Congress has acted to take the field. The Court also considered whether any rates were so low as to be confiscatory. After reviewing the master’s valuations and apportionments, the Court concluded that the stockholders had not shown confiscation for two railroads, but that the Minneapolis & St. Louis company’s financial results did prove confiscation.

Real world impact

The ruling means state railroad regulators may set statewide caps on purely intrastate freight and passenger rates without automatically triggering invalidation as direct restraints on interstate commerce. Railroads may still challenge particular state rates as confiscatory, and federal law or future congressional action can alter this balance. The decision reverses most federal injunctions against Minnesota’s rates but affirms relief for the one carrier found to be deprived of a fair return.
