Department of Revenue of Ore. v. ACF Industries, Inc.

Background

Oregon charges a general property tax (an "ad valorem" tax) on real and personal property but exempts many classes of business property, such as agricultural machinery, certain inventories, timber, and motor vehicles (which pay a registration fee). Eight companies that lease railroad cars (called the "Carlines") sued, arguing that taxing their railroad cars while exempting other commercial property violates a federal law that bars state taxes that discriminate against rail carriers, 49 U.S.C. §11503(b)(4).

Reasoning

The Court focused on the whole federal statute, not just the single sentence the Carlines relied on. Other parts of the law compare railroad property only to other property that is actually taxed. The Court read that to mean exempt property is not part of the comparison class. Reading the statute this way, and given Congress’ silence about exemptions and federalism concerns, the Court concluded that the anti‑discrimination provision does not forbid a State from keeping ordinary, generally applicable exemptions while taxing railroad property.

Real world impact

The immediate effect is that Oregon’s tax on railroad cars may stand, and States nationwide can generally preserve common tax exemptions without automatically triggering a federal challenge under §11503(b)(4). The case was sent back for further proceedings consistent with this interpretation.

Dissents or concurrances

Justice Stevens dissented, arguing the statute’s ban on taxes that "discriminate" should reach exemption schemes and that courts should assess whether exemptions impose substantially heavier burdens on rail carriers. He would have remanded for that inquiry.
