Facts

California imposes a general premiums tax on both domestic and foreign insurers and also imposes a retaliatory tax on some foreign insurers when their home States impose greater burdens on California insurers than California would otherwise impose on similar insurers from those States. The retaliatory tax is calculated by comparing California's ordinary tax burden with the tax burden that a hypothetical similar California insurer would face in the foreign insurer's home State, and California imposes the difference if the other State's burden is higher. Western & Southern is an Ohio corporation doing insurance business in California since 1955, and it paid $977,853.57 in retaliatory taxes for the years 1965 through 1971. It challenged those taxes as violating the Commerce Clause and Equal Protection Clause.

Issue

Whether California's retaliatory insurance tax imposed on an out-of-state insurer violates the Commerce Clause or the Equal Protection Clause of the United States Constitution. More specifically, the case asks whether the McCarran-Ferguson Act leaves any Commerce Clause limitation in place and whether the discriminatory tax classification survives equal protection review.

Rule

The McCarran-Ferguson Act removes entirely any Commerce Clause restriction on a State's power to tax the business of insurance. However, discriminatory taxation of foreign corporations remains subject to the Equal Protection Clause, and such discrimination is valid only if it bears a rational relation to a legitimate state purpose. Under rational-basis review, the questions are whether the legislation has a legitimate purpose and whether it was reasonable for lawmakers to believe the challenged classification would promote that purpose.

Nevada imposes a retaliatory premium tax on insurers incorporated in other States when their home States would place higher aggregate insurance taxes and fees on a hypothetical similar Nevada insurer. Prairie Harbor Indemnity, incorporated in Utah, pays the tax for policies sold in Las Vegas and challenges it as an undue burden on interstate commerce.

How should a court rule on Prairie Harbor Indemnity's dormant Commerce Clause claim?

Explanation. The majority held that Congress, through the McCarran-Ferguson Act, removed entirely any Commerce Clause restriction on a State's power to tax the business of insurance. So if the challenged levy is a state tax on the business of insurance, it is invulnerable to dormant Commerce Clause attack. The insurer must rely, if at all, on some other constitutional provision.
