If there is objections to legislation done in expedited fashion they can be repealed easily via normal discussion and voting time. Maybe this would be good if it demanded at least three executive offices and three independent citizens called for the vote rather than just the Citizen-Initiator?
It'd be easier to use IRC for a "quicky vote" using either the method you described or a better method which I'm not entirely sure what, but I'm sure the Delegate should be part of this double troika. These
But this bring another issue, what type of votes are we going to be allowed to do that? You have to define this "emergency", it's only allowed when what? "time sensitive, emergency matters" isn't definition enough for me.
In case we actually go with Khem's Quorum (which should be the technical term for this), to avoid the same 6 people deciding the emergencies all the time there should also be a provision to renovate at least a third each time this "tool" is used and this vote should be done with any Citizen available in IRC able to participate, so everyone can actually participate, and such log be pasted in the forums.
Yes it does sounds complicated, but that's why I don't see the need of "emergency quicky votes" unless you surpass Ecclesia and it's intention of being.
