The case of Gibbons v. Ogden was a landmark Supreme Court case decided in 1824 concerning the power of the states to regulate interstate commerce. This case involved a steamboat owner, Thomas Gibbons, who did business between New York and New Jersey and the then governor of New Jersey, Aaron Ogden. Gibbons argued that the monopoly Ogden had was a violation of the commerce clause of the Constitution and therefore not valid. This proved to be the case. In a unanimous decision, the Supreme Court decided that this law conflicted with federal law and the powers the federal government had to regulate interstate commerce. Under the Constitution, Congress has all powers necessary and proper to carry into effect the laws that it passes. This reinforced that clause.
