Samuel Blatchford, Snow v. United States (118 U.S. 346…
“ The contention of the plaintiff in error would allow a writ of error from this court in every criminal case in a territory where the prosecution is based on a statute of the United States; and, indeed, might go still further, for the authority of every court sitting in a territory is founded on a statute of the United States. From the fact that a given criminal case involves the construction of a statute of the United States, it does not follow that the validity of 'an authority exercised under the United States' is drawn in question. ”
