Dual Federalism Law and Legal Definition

Dual federalism refers to the concept that the national government and the state governments have sovereign power in their respective spheres of authority. There is clear demarcation or separation of powers, programs, and resources. It is also called the exercise of concurrent powers, or layer cake federalism. The distinct realms of authority do not overlap and one should not intrude into the other's authority. Each government is supreme in its own sphere.
