Charles Evans Hughes, United States v. Hvoslef — Opinion of the Court
“ In legal principle, there is no distinction which can condemn the tax in the one case and save it in the other. Whether the contract of carriage covers a small lot, or a partial cargo, or an entire cargo, whether the goods occupy a part of the cargo space or the whole cargo space,-can make no constitutional difference. The charters were for the exportation; they related to it exclusively; they served no other purpose. A tax on these charter parties was in substance a tax on the exportation; and a tax on the exportation is a tax on the exports. ”
