The
Tenth Amendment (
Amendment X) to the
United States Constitution, which is part of the
Bill of Rights, was ratified on December 15, 1791. It expresses the principle of
federalism, which strictly supports the entire plan of the original Constitution of the United States of America, by stating that the
federal government possesses only those powers delegated to it by the United States Constitution. All remaining powers are reserved for the states or the people.
