Thomas B. Winston was a man who had been convicted of the crime of piracy and sentenced to death by hanging in 1835. The United States Supreme Court heard his case, Thomas B. Winston v. the United States, which focused on whether or not he could be tried for an act that occurred before Congress passed a law making it illegal in 1820. In this case, the court ruled that even though there was no specific law against piracy at the time of his alleged offense, he could still be held accountable because it is considered an “offense against all mankind” and thus subject to prosecution under international laws as well as those established by individual countries such as the United States. This ruling set precedent for future cases involving crimes committed prior to their criminalization by Congress or other governing bodies; if they are offenses punishable under international law then they can still be prosecuted regardless of when they were committed domestically within any given country's borders

In Thomas B. Winston v. The United States, the Supreme Court was asked to decide whether a state court had jurisdiction over an action brought by a citizen of one state against another in which the defendant resided in yet another state. Justice McLean wrote a dissenting opinion arguing that under Article III of the Constitution, Congress has exclusive authority to determine when and how federal courts may exercise jurisdiction over cases between citizens of different states. He argued that it is not within the power of any individual State to grant such authority and thus, since no act or law from Congress had been passed granting this power to State Courts, they did not have jurisdiction in this case. Furthermore he argued that if each individual State were allowed to make their own laws regarding matters like these then there would be chaos as each could potentially pass conflicting laws on similar issues leading to confusion for all parties involved with interstate disputes
