The Tenth Amendment is part of the Bill of Rights, which is the first 10 amendments to the Constitution of the United States. The amendment states that the Federal Government only has those powers delegated in the Constitution, and any power not listed is left to the states or the people. In simple terms, the Tenth Amendment means that the powers not given to the Federal Government by the Constitution, nor prohibited by it to the states, are reserved for the states or the people. The amendment was included in the Bill of Rights to further define the balance of power between the federal government and the states.
