In my world the dictatorship has been overthrown after a vicious mob uprising of an uncoordinated mass and one of the four military leaders taking most of the competent people (The 20% of the 80%) with her for a few months before and while this was going on. They successfully kill the king/leader, who was a dictator and not that good of a guy, but now they have to rule. I want to know how to evenly (Or at least evenish) divide the different sections and powers of government. I would also like to know how long this government would work.
So far I was planning on them becoming a council with three stages of power that overlap for some checks and balances from each other. Each council member should be roughly equal and all of their dealings must be done in a bureaucratic manner or it doesn't count as an actual legal endeavor. If three fifths of the council vote they can kick someone. If the entire council agrees they can remove a seat, if the entire council agrees and so to does three fifths of the people then a seat can be added. The police and military are being separated from each other and the secret police (as it's being dissolved) and will both operate semi-independently from each other. Currently the current leaders are the on the council for various things but if you want to just ignore it and leave them for a later problem that's fine. It won't be a problem for years due to who's in charge at the current moment so if you want to ignore it in favor of other people as the police won't receive a council member and the military may or may not. If you believe the military needs one then make it nineteen with one person being in charge of the military.
There is a rough law system in case for criminal trials but it is precedent based and the 'laws' can be overturned by three council members agreeing to change it. This number can also be changed. I don't know how the legal system should be divided but if you want to split it up or give it all to someone that works too. If you would rather not worry about it and instead focus on different things that's fine too.
The population they would need to rule over is about six hundred thousand and they have no current opposition from external or internal forces. The territory is very compact being almost entirely in one tightly populated area with the rest being the suburbs to rural areas around it.
There are eighteen council members and they would each have absolute power over their specific region, would have a half power over the police below them, and limited power over everything else. So for example:
George is the Council Member in charge of Agriculture. He is directly responsible for ordering agriculture plans and can do whatever he wants as long as he can figure out how to implement it. So if George wants to put a ban on people transporting oranges and encourage farmers to plant corn then he would have to set up a group that would check transportation coming in and inform the police to arrest people and also add it to the law books for the judges to know that it's a crime. He would also have to hire people to go and tell farmers to plant corn and determine how to enforce it. This would all be his prerogative and he would be able to fight other people if they tried to interfere. This would be an example of George's absolute power.
An example of George's half power would be telling the police that anyone found transporting oranges is to be immediately executed. He could also order the police to go seize someone's carts because they've bothered him. The problem is that the police have been charged to protect the citizens rights and if they think this is wrong then they can just not. This might result in them being fired but it's not illegal and they cannot be legally bothered in any method other than being released. I called this half power because he can order them but they might not obey.
An example of George's limited power is this. In times of a crisis then he can take control of other people's duties. The problem is that it's up to the people working for him to determine if it's a crisis. So if George hears that Susan is leaving early for the day to take of her dying grandmother and moves in to remove the ban over importing swords for the next few days, there's a chance that it might work but it probably won't. Another example is that George can walk into Susan's organization and require a copy of any paperwork.
#Current Ideology# There are currently three main groups of opinions. Some of the few things that they all agree on is a separation of police, military, and secret police and the dissolvement of the secret police. Most of them are idealists who want to genuinely do good and believe the best way is to not commit genocide, let people get an education, and make certain people are fed. Past that things get messy. The ideals can be roughly split into three groups, the rich: Who want to have property not confiscated by the government and also want luxuries like art and music to be free trade. They also don't want to pay for things and they believe the best way for this is mainly through handing power to the police as they weren't very affected by parts of it. The working class: They really just want healthcare that doesn't include the doctor recommending that they kill you and harvest you for organs, old people being allowed to live, agriculture, and to provide a united front so people think they know what's going on. The members in it basically think education is the most important part while making certain that the secret police and assassinations don't exist. They also are pushing the hardest on controlling the press because they know how effective lies can be. The other two don't particularly care about it. The previous military people: This is about three to four council members who have the most experience when it comes to working in a government. They want to make this thing work but their main example is a dictatorship. They want to make certain that the police and military can protect people in case of one going bad, a strong government that can ask fast but also have people be overridden and for it to be illegal to assassinate people who try to remove you from office or tell you your wrong.
How can I evenly divide the different sections and powers of government to eighteen people so that all eighteen people have roughly equal power levels with absolute control over their sections? Roughly how long would this government last before needing an overhaul? Would it need one?
