[GAIUS libro septimo ad edictum prouinciale. ] §6.1.36.prQui petitorio iudicio utitur, ne frustra experiatur, requirere debet, an is, cum quo instituat actionem, possessor sit uel dolo desiit possidere.
[GAIUS, in the seventh book on the Provincial Edict.] He who brings a proprietary action, in order not to sue in vain, ought to inquire whether the person against whom he is to bring the action is the possessor, or has ceased to possess by dolus.
§6.1.36.1Qui in rem conuenitur, etiam culpae nomine condemnatur.
He who is sued in an action in rem is also condemned on the ground of negligence.
culpae autem reus est possessor, qui per insidiosa loca seruum misit, si is periit, et qui seruum a se petitum in harena esse concessit, et is mortuus sit: sed et qui fugitiuum a se petitum non custodit, si is fugit, et qui nauem a se petitam aduerso tempore nauigatum misit, si ea naufragio perempta est.
Moreover, a possessor is liable for negligence: such as one who has sent a slave through dangerous places, if the slave has perished; and one who has permitted a slave claimed from him to be in the arena, and the slave has died there; but also one who has not guarded a runaway slave claimed from him, if the slave has escaped; and one who has sent a ship claimed from him to sail in unfavorable weather, if it has been destroyed by shipwreck.
