Why not make rulers approve of bans made by judges? Like what rulers have to do to make treaties go into effect. Make rulers click an approve button to make the bans go into effect or something.
On the most basic level, that cripples the Judge's authority. In some realms, where the leader is the be all end all of power, that would work fine, but in realms where a balance is maintained between ruler and judge, that balance would be destroyed by effectively taking the one measure of power a Judge has and putting it entirely in the Ruler's hands.
Even in the most dictatorial realm, the Judge keeps the balance gameplay wise and prevents the Ruler from having supreme power over all aspects of the realm's law. I think it should stay that way.
