In the United States Supreme Court case of The United States v. John Bailey, the plaintiff argued that Bailey had unlawfully removed a slave from Virginia to Ohio in violation of the Act Prohibiting Importation of Slaves passed by Congress in 1807. The defendant argued that he was not guilty because his actions were protected under Article IV Section 2 Clause 3 of the Constitution which states “No Person held to Service or Labour in one State, under the Laws thereof, escaping into another shall…be discharged from such Service or Labour”. Ultimately, it was decided that this clause did not protect Bailey and he was found guilty as charged for violating federal law prohibiting interstate transportation of slaves. This decision established an important precedent regarding slavery laws and their enforcement on a federal level throughout America during this time period.

In the case of The United States v. John Bailey, the Supreme Court was tasked with determining whether a federal court had jurisdiction to hear an indictment against Bailey for violating a state law prohibiting gaming on Sunday. The majority opinion held that such jurisdiction did exist and affirmed the conviction of Bailey. However, Justice McLean dissented from this ruling, arguing that Congress had not given any authority to federal courts in matters concerning state laws regarding public morals or religious observances. He argued further that it would be unconstitutional for Congress to do so as it would violate states' rights under the Tenth Amendment and interfere with their ability to regulate their own affairs without interference from other governments. In conclusion, Justice McLean believed that while gambling may have been prohibited by some states on Sundays due to moral or religious reasons, this should remain solely within those respective states’ purview rather than being subject to federal regulation or oversight.
