Answer: The case established federal jurisdiction over state governments.

Explanation:

The case was brought up to the Supreme Court by James McCulloch, head of the bank of the Maryland branch of the Second U. S bank, after Maryland tried to impose taxes on bank notes from the Second Bank of the United States, since it was the only bank which printed currency from outside Maryland. By invoking the "Necessary and Proper" clause of the U. S. constitution, the supreme court ruled in favor of McCulloch, by statting that the clause gave implied, unlisted federal powers to the central government that ruled supreme over state legislation, thus making Maryland's tax on U. S banknotes illegal.
