[ULPIANUS libro trigensimo ad Sabinum. ] §17.2.55.prSi igitur ex hoc conuentus fuerit qui maleficium admisit, id quod contulit aut solum aut cum poena auferet: solum auferet, si mihi proponas insciente socio eum in societatis rationem hoc contulisse: quod si sciente, etiam poenam socium agnoscere oportet: aequum est enim, ut cuius participauit lucrum participet et damnum.
[ULPIANUS in the thirtieth book on Sabinus.] Therefore, if he who committed the wrongdoing has been sued on this account, he will take away what he contributed, either alone or with the penalty: he will take it away alone, if you propose to me that he contributed this to the partnership account without the knowledge of his partner; but if with his knowledge, the partner must also acknowledge the penalty: for it is equitable that he who shared in the profit of a thing should also share in its loss.
