Suppose that Joubert survives the Battle of Novi and is the general who backs Sieyes's 18 Brumaire coup, as he originally intended. The Constitution of Year VIII is much more in line with Sieyes's original ideas, and intended to establish political stability by forming an oligarchy which will serve life terms and have basically complete control over the membership of the legislative branch, and Joubert takes up position as the military guardian and lifetime head of this new government.
What are the consequences of this?
