Portrait of Felix Frankfurter Felix Frankfurter Wisconsin v. J. C. Penney Company…

Ambiguous intimations of general phrases in opinions torn from the significance of concrete circumstances, or even occasional deviations over a long course of years, not unnatural in view of the confusing complexities of tax problems, do not alter the limited nature of the function of this Court when state taxes come before it. At best, the responsibility for devising just and productive sources of revenue challenges the wit of legislators.

We cannot, however, be too often reminded that the limits on the otherwise autonomous powers of the states are those in the Constitution and not verbal weapons imported into it. 'Taxable event', 'jurisdiction to tax', 'business situs', 'extraterritoriality', are all compendious ways of implying the impotence of state power because state power has nothing on which to operate.

The substantial privilege of carrying on business in Wisconsin, which has here been given, clearly supports the tax, and the state has not given the less merely because it has conditioned the demand of the exaction upon happenings outside its own borders. The fact that a tax is contingent upon events brought to pass without a state does not destroy the nexus between such a tax and transactions within a state for which the tax is an exaction.
