Final answer:
The Supremacy Clause in Article VI of the Constitution states that the Federal Government prevails over other layers of government when there's conflict between laws. It establishes the federal law as the 'supreme Law of the Land'.
Step-by-step explanation:
According to Article VI of the Constitution, when conflict arises between two or more layers of government, the Federal government prevails. This principle is known as the Supremacy Clause which asserts that federal law is the 'supreme Law of the Land', and therefore, any state or local laws that contradict it are deemed unconstitutional. An example of this might be a state law that goes against a federal law related to civil rights; in this case, the federal law would take precedence due to the Supremacy Clause.
