Henry Billings Brown,
Dooley v. United States (182 U.S. 222…
“ An unlimited power on the part of the Commander in Chief to exact duties upon imports from the states might have placed Porto Rico in a most embarrassing situation. The ratification of the treaty and the cession of the island to us severed her connection with Spain, of which the island was no longer a colony, and with respect to which she had become a foreign country. The wall of the Spanish tariff was raised against her exports, the wall of the military tariff against her imports, from the mother country. She received no compensation from her new relations with the United States. ”
