In The United States, Appellants v. Armand Pillerin and Others, the Supreme Court was asked to consider whether a federal court had jurisdiction over an action brought by the United States against several individuals for alleged violations of revenue laws. At issue in this case was whether or not Congress had authority under Article I of the Constitution to pass legislation that would give federal courts exclusive jurisdiction over such cases. After considering arguments from both sides, the Court held that Congress did have such authority and thus affirmed the decision of lower courts which found that they did indeed have jurisdiction in this matter. This ruling established precedent for future cases involving similar issues related to congressional power under Article I as well as providing clarity on when it is appropriate for federal courts to exercise their jurisdictional powers.

In the United States v. Armand Pillerin and Others, the Supreme Court was asked to decide whether a Louisiana state court had jurisdiction over an action brought by citizens of France against citizens of Louisiana in relation to property located in Louisiana. The majority opinion held that it did not have such jurisdiction, as the case involved foreign parties and foreign property. However, Justice McLean dissented from this decision on two grounds: firstly, he argued that under international law there is no distinction between domestic and foreign cases; secondly, he argued that even if there were such a distinction then it should be up to Congress rather than courts to make decisions about which cases are considered domestic or foreign. He concluded by stating his belief that “the power exercised by the State court was within its legitimate authority” and thus should be upheld.
