Portrait of James Moore Wayne James Moore Wayne Cross v. Harrison — Opinion of the Court

In the mean time Florida continues to be a territory of the United States, guarded by virtue of that clause in the Constitution which empowers Congress to make all needful rules and regulations respecting the territory or other property belonging to the United States. Perhaps the power of governing a territory belonging to the United States, which has not, by becoming a State, acquired the means of self-government, may result necessarily from the facts that it is not within the jurisdiction of any particular State, and is within the power and jurisdiction of the United States.

Portrait of James Moore Wayne James Moore Wayne Cross v. Harrison — Opinion of the Court

The power to regulate foreign commerce necessarily includes, as one of its incidents, the power to lay imposts on foreign goods, or even to prohibit them entry, (Vattel's Law of Nations, Bk. 1, c. 8, p. 39,) whenever the welfare of the State demands it. The right to trade with a foreign nation is therefore conventional, and the treaty that cedes the right is the measure or limit thereof-dependent on the will of the foreign sovereign, and not a right of prescription. And a foreign nation may limit its foreign trade to itself, or to its own vessels, by treaty or otherwise.
