The Supremacy Clause of the United States Constitution (Article VI, Clause 2) authenticates that the Constitution, governmental laws made agreeable to it, and agreements made below its authority, establish the supreme law of the country.
It grants that state judiciaries are obliged by the supreme law and in case of disagreement between state law and federal law, the federal law must be implemented. It also maintains that state constitutions are subservient to the federal law.
