Respuesta :
The effect was the decision that gave congress power under the necessary and proper clause act. States could also not impede on the valid constitutional excerpts powered by the Federal Government.
Answer and explanation;
-The decision or judgement in McCulloch v. Maryland case was so important because the Supreme Court ruled that the federal government could pass laws not expressly written in the Constitution, which was a victory by the federal government over the states.
-The Supreme court struck down Maryland's attempts to place a tax on the second National Bank of the U.S. The court reasoned that the tax would essentially be a measure to undermine federal power and that the Constitution forbids any action by the states to do so.
