Great Northern Railway Co. v. Minnesota

Background

The dispute was between the State of Minnesota and a railway company over unpaid taxes for the years 1901–1912, with the trial court and state supreme court ruling for the State for 1903–1912. Minnesota law imposes a tax measured by gross earnings on railways in place of regular property taxes. For interstate business, companies must report earnings in proportion to the miles run inside Minnesota compared with the whole line. The company operated a 107‑mile line hauling ore, with 87 miles in Minnesota and a 20‑mile segment, including docks, in Wisconsin.

Reasoning

The central question was whether Minnesota’s method of measuring and taxing earnings unlawfully taxed property or earnings belonging to Wisconsin, burdened interstate commerce, or violated the Fourteenth Amendment’s protections. The railroad had allocated and deducted small per‑ton amounts for dock service and paid taxes on the reduced base; the State later sued for additional taxes. The Court found the record did not show the Wisconsin portion was actually more valuable than the Minnesota portion. The line and dock service operate as a unit, the freight charge is a single integrated charge, and much of the traffic and control originate in Minnesota. On that basis and following prior decisions, the Court held the State could tax the earnings apportioned to its in‑state mileage and rejected the constitutional challenges.

Real world impact

The decision lets Minnesota collect the additional tax assessed in this case and confirms that similar gross‑earnings measures are a permissible way for a state to tax a railroad’s in‑state activity. Railroads must present clear, specific evidence to show out‑of‑state facilities alone justify excluding earnings from the in‑state tax base. The judgment below was affirmed.
