No, I think that will never happen
The reasoning behind it is slightly different. Currently, there are very simple ways to abuse the whole RA process, by "comitting" some members of a faction to take a RA seat, but then withdrawing when a critical decision comes forward; or, contrariwise, getting members that weren't elected into the RA (a good strategy when you definitely wish to get unpopular members of your list to get a seat on the RA  just let them out of the list, let other get elected, then remove these, and let your unpopular member in).
This is sadly what also happens in some democratic systems; to prevent this to happen, there are sometimes branches of government with the power to "dissolve" the RA and force new elections.
Under [i:3qp013e3]our[/i:3qp013e3] system, this is not possible, since it's the RA itself that sets its own term and the election day. So, my personal feeling is that this "gaming" aspect should be somehow kept to a minimum.
There are three good, legitimate reasons for dropping off the RA:
- accepting a voting position on either Guild or SC
- leaving the City
- RL issues (of all sorts)
Even the first one can be "gamed" (ie. people jumping from RA to the other branches just to have an "excuse" for letting unelected members to enter the RA...).
Taking this into account, one should consider ways to limit this to happen. Fines is a possibility (either to the person or to the faction). Setting up a "threshold of change" is another (ie. if more than 50% of the original RA members have been replaced, new elections have to be called). Still, artificially forcing new elections by calling for these special situations are [i:3qp013e3]another[/i:3qp013e3] form of gaming the system.
All in all, I just think that the RA could give some thoughts to this, and provide the appropriate legislation. If there is no fear of having the system "too much gamed", this whole discussion could be dropped
