[NERATIUS libro tertio membranarum. ] §6.2.17.prPubliciana actio non ideo comparata est, ut res domino auferatur: eiusque rei argumentum est primo aequitas, deinde exceptio 'si ea res possessoris non sit': sed ut is, qui bona fide emit possessionemque eius ex ea causa nactus est, potius rem habeat.
[NERATIUS on Parchments, book 3] The Publician action was not introduced for the purpose of taking the thing away from its owner: and the proof of this fact is first equity, and secondly the exception 'if that thing is not the property of the possessor': but rather that he who has bought in good faith and has obtained possession of it on that ground should keep the thing.
