Due to the conflict of interest I won't be answering this as a legal question, but I think I can satisfy most of your questions.
1.
Section 2 - The Office of the Delegate and Vice Delegate
2. The Coalition may not be surrendered.
Nothing explicitly stated, but the intent of this basically the same.
2.
Article 2: Bill of Rights.
9. The freedom to reside in the region of The South Pacific, and the right to not be ejected or banned without reasonable cause and due process of law.
So an indisputable no.
3.
Article 10: Amendments
2. All Citizens have the right to request a Great Council for a review of the entire Charter, Bill of Rights, and Code of Laws. A Great Council may only be called once every six months.
Great Councils are legal and can fully replace the charter if desired. But it was also less than six months ago, so it's not legal.
