Final answer:
The McCulloch v. Maryland case resulted in the expansion of federal power and the establishment of the doctrine of implied powers. It affirmed the principle of national supremacy.
Step-by-step explanation:
The outcome of the McCulloch v. Maryland case was the expansion of federal power. In this landmark Supreme Court case in 1819, Chief Justice John Marshall asserted that Congress could create a national bank, even though the Constitution did not expressly authorize it. The case established the doctrine of implied powers, which means that the federal government can create policy instruments deemed necessary and appropriate to fulfill its constitutional responsibilities. Additionally, the case affirmed the principle of national supremacy, stating that the Constitution and legitimate federal laws take precedence over state laws.
