Answer:
McCulloch v. Maryland, 17 U.S. (4 Wheat.) 316 (1819), was a landmark U.S. Supreme Court decision that defined the scope of the U.S. Congress's legislative power and how it relates to the powers of American state legislatures. The dispute in McCulloch involved the legality of the national bank and a tax that the state of Maryland imposed on it. In its ruling, the Supreme Court established firstly that the "Necessary and Proper" Clause of the U.S. Constitution gives the U.S. federal government certain implied powers that are not explicitly enumerated in the Constitution, and secondly that the American federal government is supreme over the states, and so states' ability to interfere with the federal government is limited.hope this helps
