This is false.

This is the Supreme Court's main function, as it allows the court to check the power of both the legislative branch and executive branch.

The case was a 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.
