Supremacy Clause

Clause of the U.S. constitution

The Supremacy Clause of the Constitution of the United States 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. It provides that state courts are bound by, and state constitutions subordinate to, the supreme law. However, federal statutes and treaties must be within the parameters of the Constitution; that is, they must be pursuant to the federal government's enumerated powers, and not violate other constitutional limits on federal power, such as the Bill of Rights—of particular interest is the Tenth Amendment to the United States Constitution, which states that the federal government has only those powers that are delegated to it by the Constitution. It is the responsibility of the United States Supreme Court in that case to exercise the power of judicial review: the ability to invalidate a statute for violating a provision of the Constitution.
