Answer:
The McCullough vs Maryland and the Gibbons vs. Ogden case both ensured that the power of the federal government increased.
Step-by-step explanation:
In the McCullough vs. Maryland case the state of Maryland tried to put a tax on the National bank that was within its jurisdiction. However, the Supreme Court ruled that the state government did not have the power to do this thanks to the supremacy clause.
The Gibbons vs. Ogden case reinforced Congressional power in terms of regulating interstate commerce. This was done after ruling that the monopoly received by Ogden was a clear violation of federal law. This case ensured that federal laws remained superior to state laws.
