I agree with most of what has been said.
This is what we have:
A Delegate
B Ministers
C Chief Justice
D Speaker
E Senate
F Sworn Citizens
G Registered Users
H Resident Nations
There will always be some (H) who are not in (G). They are not represented unless they telegram or rmb post, which I must let you know, many of them do put forth political opinions, whether they are spies or not, it can't be proven. Limiting their say can be justified on the grounds they in 90% of cases have the ability to get into (G) (F) or (E) without any serious obstacle.
There will always be some (G) who are not in (F). These are newbies who are not noticeable, or they are long time members who don't care about the political system. Limiting their say can be justified on the grounds that they chose not to participate.
The same argument can be made for those (F) who are not in (E) but a different degree of involvement. The current constitution gives them political power, in the referendum, but does not require them to be active in order to keep their political power.
Now (E) is the most important group I think, because they need to reform the system to make it work properly. Under our constitution they are the ones who have to make the reform, but it is impossible to do it without (C) and (A). If (C), (B) and (A) are excluded from this body, their number is too small to thrive and be representative.
Excluding (D) from (B) makes sense, but it would be beneficial to lose that restriction in emergency situations.
Excluding (E) from (B) would be fatal.
In a freer system, (B) would not need to be taken from within (F), they could be taken from (G) or (H) as well. It's not neat but it does open things up.
The trouble we had is there were no (B), people were denying being in (E), hesitant to appoint (D), (C) was AWOL, (A) was against the system and so was most of (F). Calls for reform were coming from all sections of society that were not completely incapacitated. The loudest voice heard was for monarchic revolution though.
I think your ideas are going the right way, am not trying to derail them, just filling you in with how I see things. The referendum was seen as a bane due to the above difficulties, but mainly due to the fact the delegate did not co-operate.
