Answer:
McCulloch vs. Maryland ruling strengthened the national bank.
Step-by-step explanation:
McCulloch vs. Maryland was the Supreme court decision which added to the federal government's influence over the economy. In this case, Maryland wanted to tax the national bank, and a cashier named McCulloch declined to pay the tax. The Supreme Court ruled that the federal bank was constitutional and that the federal government was above the state, meaning that the state could not tax the federal government.
