"The Supremacy Clause of the Constitution of the United States (Article VI, Clause 2) establishes that the Constitution, federal laws made pursuant to it, and treaties made under its authority, constitute the "supreme Law of the Land", and thus take priority over any conflicting state laws.[1] It provides that state courts are bound by, and state constitutions subordinate to, the supreme law."
"The Supremacy Clause is essentially a conflict-of-laws rule specifying that certain federal acts take priority over any state acts that conflict with federal law. Some jurists further argue that the clause also nullifies federal law that is in conflict with the Constitution, although this is disputed."

"The Supremacy Clause operates whether the authority of Congress is express or implied, and whether plenary or dependent upon state acceptance."
