Stephen Johnson Field,
Welton v. Missouri — Opinion of the Court
“ Where the business or occupation consists in the sale of goods, the license tax required for its pursuit is in effect a tax upon the goods themselves. If such a tax be within the power of the State to levy, it matters not whether it be raised directly from the goods, or indirectly from them through the license to the sealer; but, if such tax conflict with any power vested in Congress by the Constitution of the United States, it will not be any the less invalid because enforced through the form of a personal license. ”
