Many Supreme Court cases explain the plenary powers of congress and three of the most important cases are “Gibbons v. Ogden”, “Perrin v. the United States”, and “McClanahan v. Arizona State Tax Commission”. According to the Gibbons v. Ogden case, the power to regulate interstate commerce was granted to Congress over the states by the constitution of the United States in the commerce clause. This happened when Ogden and gibbons’ partnership fell apart when Gibbons operated another steamboat on the route in New York route that belonged to Ogden. Due to that reason, Ogden filed the case in the New York court against Gibbons by receiving the permanent injunction. Gibbons's argument was rejected by the New York court declaring that interstate commerce is controlled by congress, not the states (Gibbons v. Ogden, n.d.).

Same like the gibbons and Ogden case, Perrin v. the United States and McClanahan v. Arizona State Tax Commission are two other important cases in the history of the United States of America that show the plenary power of Congress over the federal government of the United States, which according to many critics is acceptable unless and until it is exclusive and preemptive, but is deplorable when it is applied absolutely, and interestingly it is often misused by the congress due to its self-asserted unlimited powers, as it is not enumerated in the constitution to have absolute powers.
