Bulgarus De arbitris, Vat. lat. 8782, fol. 95rb

Iudex si depravatus pretio uel gratia perperam iudicauit uindictam non modo existimationis et fame, uerum etiam litis dispendium sustinebit (If a judge is corrupted by money or influence and judges completely wrongly he shall suffer not only  the value of the wrong and infamy but he shall also sustain the expenses of the trial).

Si per inscientiam et inprudentiam male iudicauit condempnabitur quatinus uidebitur equum religioni iudicis iudicantis de ea re (If the judge judges wrongly through a lack of knowledge or ignorance he shall be condemned to pay according to the conscience of the judge who will consider his case).

<Constitutio 43>

Si iudex litem suam fecerit

Iudex si accepta pecunia reum quem criminis et mortis fecerit, capitis periculo subiacebit.

Constitutiones Friderici II  2.50.2

Si iudex fraudolenter atque dolose sententiam contra leges protulerit, auctoritate iudiciaria inrecuperabiliter cadat, notetur infamia, rebus eius omnibus publicatis. Quod is ignorantia a iuris sententia oberraverit, ferens iudicium pro simplicitate animi manifesta, regie misericordie et providentie subiacebit.
