OK, let's try to make some concrete progress! 
This thread assumes that we consider the results of the poll on where to start from as binding, and we have decided to modify the three books from DG2.
The preamble taken from DG2's constitution is as follows.
I propose keeping this intact, except for changes related to possibly using a different name for our great nation.
Section A of the DG2 constitution is shown here.
I propose striking or rewording the right to demand satisfaction because that clause caused problems during DG3 Term 3. The intent here is that an injured party has the right to file a complaint against the offending individual, and to have that complaint handled in a fair and impartial way. The term "demand satisfaction" in a historical context meant the right to challenge the accused to a duel, and the PI process is often used in that context. In the U.S. constitution this is handled by the term "equal protection under the law". Another term which is often seen in contracts is "redress of grievances". The key thing to try to get written down is that one is not guaranteed "satisfaction", only that a complaint is dealt with fairly.
Section B and C taken from the DG2 constitution are:
I propose keeping these sections intact. Polls already indicated that we want to modify the Three Books, and have three branches of government.

The preamble taken from DG2's constitution is as follows.
We, the people of Fanatika, in order to create an atmosphere of friendship and cooperation, establish this Constitution of our beloved country.

I propose keeping this intact, except for changes related to possibly using a different name for our great nation.
Section A of the DG2 constitution is shown here.
A. All Civfanatics Forum users who register in the Citizen Registry are citizens of Fanatika. Citizens have the right to assemble, the right to free movement, the right to free speech, the right to a fair trial, the right to representation, the right to demand satisfaction and the right to vote.

Section B and C taken from the DG2 constitution are:
B. Governing rules shall consist of the Articles of the Constitution, the Code of Laws and the Code of Standards. No laws shall be passed that conflict with an article and no standards shall be used that conflict with a law or an article.
C. The government will consist of the Executive Branch, Legislative Branch and Judicial Branch.
I propose keeping these sections intact. Polls already indicated that we want to modify the Three Books, and have three branches of government.
