Question juridique clé
Whether the buyer had to pay the plaintiffs the amount of the realized pledge loss after failing to release the pledged security.
Solution extraite
Yes. By undertaking to release the pledged security, the buyer also had to free the plaintiffs from the personal debt attached to the pledge; after realization, the plaintiffs could claim direct payment.
Motifs extraits
The court treated the undertaking as a release promise under Art. 175 OR, applicable to the plaintiffs' personal liability arising from the debt certificates. Once the securities were realized, the risk of double payment no longer justified limiting the claim to payment to the bank. The contractual breach caused a compensable loss when the pledge loss debt arose, not only upon later payment.
