Second paragraph of Article VI of the US Constitution:

This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any State to the Contrary notwithstanding.

It's known as the Supremacy Clause.

Problem: the Federal Constitution prohibits congress from enacting the establishment of a religion… how is barring sharia law from the State's own legal-system establishing a religion? Moreover, how can the first-amendment, which prohibits Congress from doing so, prohibit the states from doing so without the mechanism itself altering the text of the first amendment? And if the text thereof is altered, by what authority is it altered?

Seems to me that this law is just codifying the Supremacy Clause in Oklahoma, saying that no judge can use foreign or cultural laws to run roughshod over the Constitution.

The fact that CAIR has a problem with that should tell everybody all they need to know.
