Canon 12
On seditious bishops
If someone was ordained a bishop and does not want to take over a diocese for which he was appointed, but wants to be ordained somewhere else and acts violently and seditiously against those who have ordained him, he shall be removed from his office. If, however, he wants to remain in his previous office of presbyterate, he shall not be forbidden to retain what he have had. But if he resists, he shall be deposed also from the presbyterial office by a proper decision.
