I believe if a state and federal law contradict each other the federal law wins. But the state law does not have to be reversed, even though it is meaningless. It’s pretty stupid but just means if the federal law is ever changed your state law is already in place. Now this law was written before Arizona was a member of the USA so I have no idea if unconstitutional laws had to be removed or not before joining the union. The supreme Court of Arizona pretty much said “this is what we think it is, but until there is a court case we don’t know.”
