Look up the various references (at least some of them) and you will begin to understand the courts are ruled under corporate contractual law, which is not subject to the juridiction of the constitution. His entire appeal rests upon his ability to prove that this court is extra-constitutional and that a fraud was perpetrated upon him - most citizens actually - from the day he was born and registered on a birth certificate. The UCC recognizes him as a asset of a corporation (The United States of America). He is making the claim that he is a free human being not subject to any such UCC - that to the extent he has erroneously entered into any agreement with a corporation known as The United State of America, it was done under fraudulent circumstances and therefore any such agreement is null and void.
Therefore he is not subject to UCC rules...he is outside the system. He claims to be a soviergn citizen of Colorado and a Member of the united states of America, something quit different from The United States of America, which is a corporation.
His argument is that he is subject to common law and not corporate law.
