The legit one is the Constitution FOR The United States.

It doesn't matter, though, because the US has been under Martial Law since FDR, who also characterized US citizens as Enemies of the State, via the "Trading With The Enemy" Act of 1917.

Gold-fringed Flags in courtrooms tell you that the Court is operating under Admiralty Law, not Common Law, so if you try to use the Constitution as a defence, you will be cited for Contempt of Court, and might be thrown in the brig, for a few days.
