What is the result of the supreme court's decision in the McCulloch v. Maryland case?

The federal government gained powers not explicitly mentioned in the constitution

The ruling in McCulloch v. Maryland was a landmark decision of the United States Supreme Court. The state of Maryland attempted to prevent the operation of a subsidiary of the Second Bank of the United States by imposing a tax on all banknotes of banks not based in Maryland. The Second Bank of the United States was the only bank then present in the state that had not been founded in this. It was recognized in the court's decision that the state had specifically directed the Bank of the United States. The Court invoked the Theory of Implicit Powers of the Constitution, which allowed the Federal Government to enact laws that are not expressly provided for in the Constitution, from a list of expressed powers, provided that such laws are useful for Congressional powers under the Constitution.

The case cited is a milestone in world history, as it marked the beginning of the theory of implicit powers.
