Summary

Portrait of Salmon P. Chase Salmon P. Chase License Tax Cases — Opinion of the Court

Congress cannot tax exports, and it must impose direct taxes by the rule of apportionment, and indirect taxes by the rule of uniformity. Thus limited, and thus only, it reaches every subject, and may be exercised at discretion. But, it reaches only existing subjects. Congress cannot authorize a trade or business within a State in order to tax it.
If, therefore, the licenses under consideration must be regarded as giving authority to carry on the branches of business which they license, it might be difficult, if not impossible, to reconcile the granting of them with the Constitution.

But such a scheme of taxation applied to communities whose exclusive and paramount legislation proscribes the taxed pursuit as common and public nuisances, imputes every step in such pursuit as a crime, and punishes every transaction out of which the tax is raised by fine and imprisonment, and requires every grand jury to be specially charged to inquire into every perpetration of these crimes, is an absurdity.

Whatever room for argument there may be as to the competency of State legislation to extinguish material products, as sources of internal revenue to the United States, by proscription of their legal use while their actual use continues, it can never be tolerated that personal vice and guilt constitute a fund for Federal taxation, which ousts the States of police and penal regulation of the personal conduct of their inhabitants.
