The principle of stated that the federal governments power should be limited to those clearly assigned to it by the constitution?

The principle that the federal government's power should be limited to those clearly assigned to it by the Constitution is known as "enumerated powers." This concept is rooted in the idea of federalism, which emphasizes the division of authority between national and state governments. The Constitution explicitly outlines the powers granted to the federal government, suggesting that any powers not mentioned are reserved for the states or the people, as articulated in the Tenth Amendment. This principle aims to prevent an overreach of federal authority and protect individual liberties.
