[ULPIANUS libro nono disputationum. ] §9.2.49.prSi quis fumo facto apes alienas fugauerit uel etiam necauerit, magis causam mortis praestitisse uidetur quam occidisse, et ideo in factum actione tenebitur.
[ULPIANUS, in the ninth book of Disputations.] If anyone, by making smoke, has chased away or even killed someone else's bees, he is considered rather to have furnished the cause of death than to have killed them, and therefore he will be held liable under an action on the case (in factum).
§9.2.49.1Quod dicitur damnum iniuria datum Aquilia persequi, sic erit accipiendum, ut uideatur damnum iniuria datum, quod cum damno iniuriam attulerit: nisi magna ui cogente fuerit factum, ut Celsus scribit circa eum, qui incendii arcendi gratia uicinas aedes intercidit: nam hic scribit cessare legis Aquiliae actionem: iusto enim metu ductus, ne ad se ignis perueniret, uicinas aedes intercidit: et siue peruenit ignis siue ante extinctus est, existimat legis Aquiliae actionem cessare.
When it is said that the Lex Aquilia pursues damage unlawfully caused, it must be understood in this way: that damage is considered to be unlawfully caused which has brought unlawfulness along with the damage; unless it was done under the compulsion of a great force, as Celsus writes concerning him who pulled down a neighboring house for the sake of averting a fire. For he writes here that the action of the Lex Aquilia does not lie; for, led by a well-founded fear lest the fire should reach him, he pulled down the neighboring house. And whether the fire reached it or was extinguished beforehand, he estimates that the action of the Lex Aquilia does not lie.
