The following is from BALZAC v. PEOPLE OF PORTO RICO, 258 U.S. 298 (1922):
The United States District Court is not a true United States court established under article 3 of the Constitution to administer the judicial power of the United States therein conveyed. It is created by virtue of the sovereign congressional faculty, granted under article 4, 3, of that instrument, of making all needful rules and regulations respecting the territory belonging to the United States. The resemblance of its jurisdiction to that of true United States courts, in offering an opportunity to nonresidents of resorting to a tribunal not subject to local influence, does not change its character as a mere territorial court.
