Kansas City S. Ry. v. Koeller

The Railroad Revitalization and Regulatory Reform Act prevents states and their subdivisions from imposing discriminatory taxes against railroads. 49 U.S.C. 11501. In 2008, the drainage district, a subdivision of Illinois, changed its method for calculating assessments. All other owners are assessed on a per-acre formula, but railroad, pipeline, and utility land were to be assessed on the basis of "benefit," apparently based on the difference in value between land within the district and land outside the levees; annual crop rentals being paid; and agricultural production of lands within the district. Two rail carriers brought suit under a section of the Act, which prevents imposition of "another tax that discriminates against a rail carrier." The district court held that the assessment was prohibited by the Act, but concluded that it was powerless to enjoin the tax. The Seventh Circuit reversed, holding that the court has authority to enjoin the tax, but, under principles of comity, should eliminate only the discriminatory aspects, not the entire scheme. The assessment is a tax that, raises general revenues; its ultimate use is for the whole district. It imposes a proportionately heavier tax on railroading than other activities.
