When a judge threatens, browbeats, sends out, or unjustly silences any one of the disputants in his court, he shall first of all be punished with the first amercement. If he defames or abuses any one of them, the punishment shall be doubled. If he does not ask what ought to be asked, or asks what ought not to be asked, or leaves out what he himself has asked, or teaches, reminds, or provides any one with previous statement, he shall be punished with the middle-most amercement.
