To clarify– we should limit the power of mass bans. We shouldn't make them a worthless strategy, or a nonexistent strategy. Putting a stay on bans will indeed ensure that no judge ever bans any politically powerful segment of nobles– because he knows that, not only will he be protested out of power, the bans aren't even going to go into effect.
I don't agree.
My understanding is that the only reason this is not true under the current system is because of an oversight in another abuse-prevention measure: Judges cannot access bans at all in their first day in office, either to place or lift them.
If not for that, the sequence of events now would be: Judge mass-bans, Judge is protested out of office, next turn new Judge is appointed, new Judge removes bans.
There's not really a significantly better chance, politically, of protesting out the Judge given an additional day. If you could have protested him out given two days, you could almost certainly have protested him out given one, provided everyone was active—y'know,
allowing for OOC factors that shouldn't be determining the course of a realm's existence.
So the main thing gained by this is the assurance that you will not have a Judge who has banned the entire realm sitting happily in his position with everyone else banned, purely because not quite enough people were able to log in in time to see the damage and react to it.
