Answer:
preemption
Explanation:
The principle of federal preempition is the principle by which the fedarl government has the power to override any local or state law if it sees that it is against the federal law, this is because in the constitution it states that all of the states that form the United States shall be under the federal law, and they can´t act against the federal law, if a state does something that is unconstitutional or goes against the federal law, the federal government can override that local or state law.
