Summary

Background

The State of Texas sued a Texas oil company to recover taxes under a 1905 law (the Kennedy act). Section 9 imposed a two percent occupation tax on wholesale dealers in coal oil, naphtha, benzine, and other mineral oils, based on gross receipts or market value. The oil company argued the law violated the Fourteenth Amendment by denying equal protection and depriving property without due process; it also raised arguments about penalties and a possible commerce question, but the company relied mainly on the Fourteenth Amendment in the courts.

Reasoning

The central question was whether the occupation tax and its enforcement procedures violated the Fourteenth Amendment’s guarantee of due process or equal protection. The Court treated the levy as an occupation tax and said a State may classify occupations for taxation so long as the classification is not shown to violate the Constitution. The Court reviewed prior decisions holding that States may adopt different taxes or rates for different classes and found no showing that Texas’s classification was beyond legislative power. The Court also noted the penalties were not sought or imposed in this suit, so they did not decide whether penalties might be invalid.

Real world impact

The Court affirmed the state courts’ judgments, allowing Texas to proceed to collect the tax in its own courts. The decision leaves to the State broad authority to classify businesses for tax purposes and does not let federal courts strike down such classifications merely because they seem unwise. Because penalties were not awarded here, questions about the statute’s enforcement penalties remain unresolved.
