I think this is a necessary power, which won't be
abused. But if there
are concerns here about abusive mass expulsions to retain control,
the power could simply be limited to a max of 10 expulsions per year by
tacking onto AoA 4.4 something like:
That's open to abuse - get a group of 11 people together and start
causing trouble! A general meeting ought to be able to override such a
decision in the unlikely event that it is abused (I think general
meetings can do pretty much whatever they like as long as it doesn't
explicitly contradict the Articles or the law).
