The United States v. Sheldon was a Supreme Court case that involved the interpretation of the Judiciary Act of 1789. The defendant, Sheldon, had been convicted in a circuit court for violating an act prohibiting trading with foreign nations without permission from Congress. He argued that he should have been tried by jury instead because his offense was punishable by more than five dollars and thus fell under the jurisdiction of common law courts as outlined in the Judiciary Act of 1789. The Supreme Court disagreed and held that while it is true that certain offenses are subject to trial by jury according to common law, this does not apply when such offenses are prohibited or regulated by acts passed specifically by Congress; therefore, since Sheldon’s offense was prohibited directly through legislation rather than at common law, he could be tried without a jury in circuit court. This decision established precedent for interpreting federal statutes over state laws when they conflict with one another on matters related to criminal prosecution and punishment.

In the United States v. Sheldon, Chief Justice John Marshall delivered a dissenting opinion in which he argued that Congress had no authority to pass laws regulating private contracts between individuals. He argued that such matters should be left to state legislatures and courts as they are better equipped to handle them than federal government officials. Furthermore, he stated that if Congress were allowed to regulate these types of agreements it would lead to an increase in federal power and diminish the sovereignty of states over their own affairs. In conclusion, Marshall believed that any attempt by Congress to interfere with private contracts was unconstitutional and beyond its scope of authority under the Constitution.
