Bowman v. Continental Oil Co.

Background

Continental Oil Company sued New Mexico officials to stop enforcement of a state law that put a two‑cent excise tax on each gallon of gasoline and a $50 annual license for each distributing station. The company buys gasoline outside New Mexico and ships it in. It sells some gasoline in original packages (tank cars, barrels, or cans) and sells larger amounts in broken packages or bulk to customers. The parties agreed that about 94.5% of sales were bulk or broken packages, 5.5% were sales in original packages, and the company consumed gasoline equal to about 8% of its sales. Continental argued the taxes violated the federal Constitution’s protection for interstate commerce and state constitutional rules about taxation.

Reasoning

The Court examined whether parts of the law could be separated so the State could tax domestic activity without harming interstate commerce. It agreed the annual license tax was inseparable and therefore could not be enforced because it would burden interstate business at the same stations. But the two‑cent excise, set by the number of gallons sold or used, was divisible. The Court ruled the excise cannot be charged on gasoline brought into New Mexico and sold in the same original packages (an interstate delivery), but it can be collected on gasoline sold from broken packages and on gasoline used by the company. The Court reversed the district court in part, enjoined collection of the license tax as applied to the company, and remanded with instructions allowing excise collection where lawful and permitting the State to require detailed reports.

Real world impact

This decision protects companies that bring and sell gasoline in original sealed shipments from state taxation, while letting states tax bulk in‑state sales and fuel used by distributors. New Mexico may still collect excise revenue on domestic bulk sales and company use, and may require reporting to enforce those lawful taxes.
