State and Federal Constitutions
Federal preemption occurs when a higher authority of law supersedes or overrides the law of a lower authority. In the context of federal-state relations, this principle often means that if Congress has legislated on a subject matter, state laws conflicting with federal laws can be invalidated. This is crucial in understanding how power and authority are distributed between federal and state governments, especially during emergencies or crises when quick and decisive action is often necessary.
