The Tenth Amendment is part of the Bill of Rights, which is the first ten amendments to the United States Constitution. It was included to define the balance of power between the federal government and the states. The amendment states that the federal government has only those powers specifically granted by the Constitution, such as the power to declare war, to collect taxes, and to regulate interstate business activities. Any power not listed in the Constitution is left to the states or the people. The Tenth Amendment emphasizes that the inclusion of a bill of rights does not change the fundamental character of the national government. Although the Tenth Amendment does not specify what these “powers” may be, the U.S. Supreme Court has ruled that laws affecting family relations, commerce that occurs within a state’s own borders, and local law enforcement activities are among those specifically reserved to the states or the people.
