A pledge, however, is for the benefit of both parties; of the debtor, because it enables him to borrow more easily, and of the creditor, because he has the better security for repayment; and accordingly, it is a settled rule that the pledgee cannot be held responsible for more than the greatest care in the custody of the pledge; if he shows this, and still loses it by some accident, he himself is freed from all liability, without losing his right to sue for the debt.

The Servian action is that by which a landlord sues for his tenant's property, over which he has a right in the nature of mortgage as security for his rent; the quasi-Servian is a similar remedy, open to every pledgee or hypothecary creditor.
"The Institutes of Justinian"
Caesar Flavius Justinian
Again a pledgor who pledges his stock not in good faith as security for a loan, but to enable the pledgee to vote it and effect an unlawful purpose, cannot do this and so defeat a statute which provides that the real owner, the pledgor, may vote his stock.
