[IDEM libro octauo regularum. ] §20.1.25.prCum uitiose uel inutiliter contractus pignoris intercedat, retentioni locus non est, nec si bona creditoris ad fiscum pertineant.
[THE SAME, in his eighth book of Rules.] When a contract of pledge is entered into defectively or ineffectually, there is no room for retention, not even if the goods of the creditor should fall to the treasury.
