doctrine of preemption

The Doctrine of Preemption is a legal principle that allows federal law to take precedence over state laws when there is a conflict. This means if a state law contradicts a federal law, the federal law will apply instead. The idea is to ensure a uniform legal framework across the country, especially in areas where national interests are involved. Preemption can be explicit, where federal law clearly states it overrides state law, or implied, where the federal government’s intent to occupy a regulatory field is inferred, making state involvement unwarranted.
