I dislike this Citizen-.... (fill-in position name) formulas, they sound so phony, like you need to affirm that they are elected and not some sort of Egyptian gods. I liked the titles we or some other regions had used before, be it made-up ones or the Ministers position we had.
On top I can't help but picturing the Sergeant as a fat guy with a 'stache who is playing military and hurries up to go home cuz it's 5 pm and his wife is waiting with supper. Again, the one who serves, not the one who commands. It sounds like an attending officer, the one who makes sure you have enough socks and your nails are clean.
I love the use of a random "coin-toss" instrument for breaking up ties. Simple and effective.
I agree with Prydania on re-introducing the application and grilling process of a citizen into the parliamentary assembly of the region.
Not sure how you want to empower the Directorate and the individual executives but have this in there: 5. The Ecclesia may regulate foreign, domestic and military policy by law. That is too vague for my taste. I believe that any new executive will have to present a governance program and the Parliament will discuss and sanction it, amending and requesting modifications, if necessary.
3. The Ecclesia may remove any government official by a majority vote. - for any or no reason?
Futhermore, I did love a system with a more elaborate government rank: 3. The Citizen-Steward will serve as head of government and conduct domestic policy. - who the heck is this government?
))) just this guy and the poor Sergeant. You could call it a couple or a pair instead of the government.
