Brown-Forman Co. v. Kentucky

Background

The Commonwealth of Kentucky sued to collect a license tax imposed by a March 26, 1906 law that taxed every person or company in the State who compounds, rectifies, adulterates, or blends distilled spirits called "single stamp spirits" at one and one‑fourth cents per wine gallon. A company that rectifies spirits challenged the tax, arguing it did not apply to certain products, that it violated the State constitution, and that it denied the equal protection guaranteed by the Fourteenth Amendment and improperly regulated interstate commerce. A separate section of the law targeted deceptive shipments labeled as Kentucky whiskey, but the company was not charged under that section.

Reasoning

The Court focused on the federal equal protection claim. It accepted the Kentucky Court of Appeals’ interpretation that the statute imposes a license or occupation tax on the business of rectifying and blending, not a property tax on the spirits themselves. The Court explained that States have wide discretion in classifying businesses for taxation, and that distinguishing in‑state rectifiers from straight distillers or from businesses operating entirely outside Kentucky is not arbitrary. The State cannot tax businesses conducted wholly outside its borders, and the separate shipment provision did not change the conclusion. Finding reasonable differences in classification, the Court affirmed the state court judgment.

Real world impact

The ruling lets Kentucky collect the specific license tax from businesses that do rectifying or blending in the State. It leaves out‑of‑state producers untaxed unless they actually carry on the taxed business in Kentucky. The decision upholds the state court’s reading rather than creating a new national rule on interstate commerce.
