Overview#United States Federal Law and treaties, so long as they are in accordance with the Constitution, preempt conflicting state and territorial laws in the 50 U.S. states and in the territories.
However, the scope of United States Federal Law preemption is limited because the scope of federal power is not universal. In the dual-sovereign system of American federalism (actually tripartite because of the presence of Indian reservations), states are the plenary sovereigns, each with their own Constitution, while the federal sovereign possesses only the limited supreme authority enumerated in the Constitution.
