Key legal question
Whether the bank could offset its claims from post-bankruptcy debt certificates against the debtor's bank account balance.
Extracted holding
The offset was ineffective because the account funds fell under the contractual and statutory restrictions on compensation, and the debtor could validly oppose compensation by relying on the no-better-fortune exception.
Extracted reasoning
The banking relationship was treated as an irregular deposit; under Art. 125 Nos. 1 and 2 CO, the bank could not set off against the debtor's protected claim. The debtor's later bankruptcy did not remove the restriction, and the cessionary creditors could invoke the same position because they pursued the debtor's claim in place of the estate.
