In the case of Brig James Wells v. The United States, the Supreme Court was asked to decide whether a ship captain could be held liable for damages caused by his vessel while in service of the government. At issue was whether Captain Wells had been negligent in failing to properly secure and protect his vessel from damage during a voyage on behalf of the United States Navy. The court ultimately found that Captain Wells had acted negligently and was therefore responsible for any losses sustained as a result of his negligence. In its decision, the court noted that it is incumbent upon those who serve their country with vessels to take all necessary precautions against potential harm or loss due to their actions or omissions. As such, they are accountable for any resulting damages incurred by third parties as well as themselves when acting on behalf of their nation's interests at sea.

In Brig James Wells v. The United States, the Supreme Court was tasked with determining whether a vessel that had been captured by an American privateer during the War of 1812 could be considered a prize of war and thus subject to condemnation proceedings in federal court. Justice Johnson delivered the dissenting opinion, arguing that Congress did not have authority under Article III of the Constitution to vest jurisdiction over such matters in federal courts. He argued that since this case involved two citizens from different states, it should have been heard by state courts instead. Furthermore, he noted that even if Congress had intended for these cases to be handled by federal courts, they would still need explicit authorization from either an act or treaty before doing so; no such authorization existed here as far as he knew. Therefore, Justice Johnson concluded that there was no basis for granting jurisdiction over this matter to any court other than those established at common law within each state's boundaries.
