Facts of the Case

The Hawaii Liquor Tax, enacted in 1939, imposed a twenty percent excise tax on wholesale liquor sales. Certain locally produced alcohol products, such as okolehao brandy and fruit wine, were exempt from the tax. Bacchus Imports, a liquor wholesaler, challenged the law's validity and sought a refund of $45 million from the state of Hawaii.

Question

Did Hawaii law violate the Import-Export Clause and the Commerce Clause of the Constitution?

Conclusion

The Court found that the Hawaii Liquor Tax violated the Constitution. Justice White reaffirmed what he called a "cardinal rule of Commerce Clause jurisprudence" in arguing that states are prohibited from imposing taxes which discriminate in the traffic of interstate commerce. Since the law was originally enacted to support local industries in Hawaii, and the alcoholic products which the law exempted competed with different beverages produced outside the state, Justice White concluded that there were clear constitutional violations in this case.
