This Supreme Court decision is one of the most important decisions of the early United States
. It effectively asserted the Federal Government's superiority over the states and prevented the states from interfering with the general decisions of the Federal government. In doing so, the Supreme Court also granted the Federal Congress with a variety of powers not expressly stated in the Constitution, and set the precedent for the interpretation of the Constitution as the basis for many laws in the future of the United States. Without this decision by the Supreme Court, Congress would not be able to pass many of the laws necessary to benefit the common good of the country, and would thus be exponentially weaker. This decision of McCulloch v. Maryland was entirely correct because it allowed Congress the freedom to interpret the spirit of the Constitution, rather than the specific letter of the law and gave Congress the power to enact many laws implied by the Constitution that they would otherwise not be able to pass. This decision was also correct because it ended the bickering between the states and the Federal government over implied and expressed powers, and asserted once and for all that the Federal government was to be the final authority on all national matters, rather than the states.
