I know that the States has some independent from Washington DC

I also know things like the military and foreign affairs is decided from Washington and some domestic laws is up the each States.

But who far goes this independent and when does United States Constitution, take over ?

Read an article in a Danish newspaper about some organization who had dragged their states into court for breaking federal laws and the sentence was:
United States Constitution had been violated and the Law from this State was therefore invalid.

It was something with open carry weapon-This State had forbidden it and three organization had accused the local government for violating the Constitution.
