Chief Justice Morrison R. Waite (unanimous): “The government of the United States is one of delegated powers alone. Its authority is defined and limited by the Constitution. All powers not granted to it by that instrument are reserved to the States or the people. No rights can be acquired under the constitution or laws of the United States, except such as the government of the United States has the authority to grant or secure. All that cannot be so granted or secured are left under the protection of the States.”
