Harlan F. Stone,
McGoldrick v. Berwind-White Coal Mining Company…
“ The fact that a use tax, sustained as a tax upon an attribute of property which is subject to the jurisdiction of the State, may have an incidental or indirect effect upon interstate commerce, and thus in the opinion of commentators may tend to discourage interstate transactions, is certainly no excuse for going further and upholding the action of States which, looking with a jealous eye upon the freedom of interstate commerce, attempt to lay a direct tax upon that commerce. ”
