Supremacy Clause

 
Article VI, Paragraph 2 of the U.S. Constitution is commonly referred to as the Supremacy Clause.  It establishes that the federal constitution, and federal law generally, take precedence over state laws, and even state constitutions. It prohibits states from interfering with the federal government's exercise of its constitutional powers, and from assuming any functions that are exclusively entrusted to the federal government. It does not, however, allow the federal government to review or veto state laws before they take effect.
