Answer:
In McCulloch v. Maryland (1819) the Supreme Court ruled that Congress had implied powers under the Necessary and Proper Clause of Article I, Section 8 of the Constitution to create the Second Bank of the United States and that the state of Maryland lacked the power to tax the Bank. Arguably Chief Justice John Marshall's finest opinion, McCulloch not only gave Congress broad discretionary power to implement the enumerated powers, but also repudiated, in ringing language, the radical states' rights arguments presented by counsel for Maryland.
At issue in the case was the constitutionality of the act of Congress chartering the Second Bank of the United States (BUS) in 1816. Although the Bank was controlled by private stockholders, it was the depository of federal funds. In addition, it had the authority to issue notes that, along with the notes of states' banks, circulated as legal tender. In return for its privileged position, the Bank agreed to loan the federal government money in lieu of taxes. State banks looked on the BUS as a competitor and resented its privileged position. When state banks began to fail in the depression of 1818, they blamed their troubles on the Bank. One such state was Maryland, which imposed a hefty tax on "any bank not chartered within the state." The Bank of the United States was the only bank not chartered within the state. When the Bank's Baltimore branch refused to pay the tax, Maryland sued James McCulloch, cashier of the branch, for collection of the debt. McCulloch responded that the tax was unconstitutional. A state court ruled for Maryland, and the court of appeals affirmed. McCulloch appealed to the U.S. Supreme Court, which reviewed the case in 1819.
