I'm inundated with distractions at the moment, so I will have to reread this material later to fully retain it, however, so far it looks very interesting.

1) How often are Representatives elected?

2) Political groups have their own territories? That's interesting certainly, what happens when one falls out of the top three (or suffer any shift in their ranking, really)? Does their territory suffer any consequences?

3) The Political Group voting system, particularly the down-voting ability, seems exploitable. Couldn't, with the appropriate organization, voters target key group members? Perhaps it would be better if only members of that Political Group could down-vote, or something similar. So that their interests are protected from external tampering. Or only people residing within their area, or something.

4) Given that they hold legislative and executive power, I imagine the Council has created a lot of bureaucratic organizations and "Federal Departments" to delegate the responsibility of carrying out laws to? Are these hypothetical bureaucracies malleable? Changing often, or remaining stagnant? And, finally (for now), I imagine they have Ministers/Administrators/Department Heads as well?

(I'm not firmly acquainted with politics myself.)
