[ULPIANUS libro septuagensimo ad edictum. ] §50.17.154.prCum par delictum est duorum, semper oneratur petitor et melior habetur possessoris causa.
[ULPIANUS, in the seventieth book on the edict.] When the fault of two parties is equal, the claimant is always burdened and the position of the possessor is held to be better.
sicut fit, cum de dolo excipitur petitoris: neque enim datur talis replicatio petitori 'aut si rei quoque in ea re dolo 'actum sit'. illi debet permitti poenam petere, qui in ipsam non incidit.
This is as happens when an objection of the claimant's malice is pleaded: for such a replication is not granted to the claimant, "or if action was also taken with malice by the defendant in that matter." It ought to be permitted to seek a penalty to him who has not himself fallen into it.
