As long as they are in your dungeon still and are not landed, you can banish them. If you were to release them, then you lose the ability to banish them unless you were to imprison them again.I remember cases when I revoked people's last title while they where my vassals and on my dungeon. Upon revocation I stopped being their liege. I can't remember if I was able to banish them then, should I be able to?
If not what's the right order to do things so that I can banish him?
