Indian Territory Illuminating Oil Co. v. Board of Equalization of Tulsa Cty.

Background

An oil company had produced crude oil from restricted Indian lands in Seminole County under leases approved by the Secretary of the Interior. The company commingled that oil with its other oil, piped it to storage tanks in Tulsa and Payne Counties, and paid the agreed 12% royalty to the Superintendent of the Five Civilized Tribes. On the assessment dates the Indians owned no part of the oil and would not share in future proceeds. Oklahoma assessed the oil as the company’s personal property for annual property taxes; the company argued the oil was exempt because it acted as an instrumentality of the United States.

Reasoning

The Court addressed whether the State’s tax was an improper burden on federal functions. It distinguished an earlier case (Jaybird Mining Co. v. Weir) where royalties had not been paid and the taxed ore remained on restricted land. Here, the royalties had been paid, the oil had been segregated and removed from the restricted lands, and it was held exclusively for the company’s benefit. The Court explained that any immunity for a government instrumentality only extends as necessary to protect government functions, and a neutral property tax on items held for a private advantage does not directly burden those functions. Because the taxed oil was the company’s property awaiting disposition, the tax was valid.

Real world impact

The decision lets states collect property taxes on oil stored off restricted lands once royalties are paid and the oil is the company’s exclusive property. The Court affirmed the Oklahoma judgments upholding the taxes, limiting federal exemption for instrumentalities to what is strictly necessary.
