McCulloch v. Maryland was a US Supreme Court decision enacted in 1819 that defined the limits of the legislative powers exercised by the US Congress in opposition to the legislative powers of the states.

It also describes the supremacy of the federal goverment over state goverments, that cannot easily interfere with the actions of the first.
