That's a false statement which is the reason for the request. There is nothing easy about banning an ex-ruler because its impossible and they are set for life.
Not quite. Banning dukes and getting away with it is quite difficult. Banning important people and getting away with it can be difficult. But if you don't care to get away with it, or if the person isn't a duke/margrave, banning him, per say, isn't hard at all.
