[IDEM libro quarto ad edictum. ] §2.4.7.prPatris adoptiui parentes impune uocabit, quoniam hi eius parentes non sunt, cum his tantum cognatus fiat quibus et adgnatus.
[THE SAME, in the fourth book on the Edict.] One will with impunity summon the parents of an adoptive father, since these are not his parents, inasmuch as he becomes a cognate only of those to whom he also becomes an agnate.
