American Fur Co. v. United States
In American Fur Co. v. United States, 27 U.S. (2 Pet.) 357, 369, 7 L.Ed. 450 (1829), the Supreme Court stated that "all the provisions contained in (the 1802) Act, and consequently, those contained in the amendatory act of 1822, are by (the first section) expressly confined" to "Indian country."
The Court, in American Fur, however, was concerned with the question of penalties for those found bringing "ardent liquors" into Indian country for trade with the Indians, and it held that only those goods of the traders found within Indian country were to be forfeited.
The Court was construing only that section of the Act, added by amendment in 1822, respecting importation of liquor into Indian country and the penalties for doing so.
