[ULPIANUS libro trigesimo primo ad edictum. ] §17.2.26.prEt ideo si socius quaedam neglegenter in societate egisset, in plerisque autem societatem auxisset, non compensatur compendium cum neglegentia, ut Marcellus libro sexto digestorum scribsit.
[ULPIANUS in his thirty-first book on the Edict] And therefore, if a partner had done certain things negligently in the partnership, but in most other cases had enriched the partnership, the gain is not set off against his negligence, as Marcellus wrote in the sixth book of his Digests.
