[PAPINIANUS libro trigensimo septimo quaestionum. ] §9.2.54.prLegis Aquiliae debitori P ante moram promissum animal uulnerauit: idem est et si occiderit animal.
[PAPINIANUS, in the thirty-seventh book of Questions.] If [someone] injures an animal promised [in delivery] before the debtor is in default, the debtor has an action under the Lex Aquilia; the same is true also if [someone] kills the animal.
quod si post moram promissoris qui stipulatus fuerat occidit, debitor quidem liberatur, lege autem Aquilia hoc casu non recte experietur: nam creditor ipse sibi potius quam alii iniuriam fecisse uidetur.
But if, after the default of the promisor, the stipulator kills the animal, the debtor is indeed released, but [the creditor] will not successfully sue under the Lex Aquilia in this case; for the creditor is deemed to have done an injury to himself rather than to another.
