Kernrechtsfrage
How to qualify the 18 September 1990 agreement: credit mandate or third-party-benefit/gurantee arrangement?
Extrahierter Entscheid
The agreement was a credit mandate under Art. 408 CO, with the bank's security and assignment duties only ancillary.
Extrahierte Begründung
The defendant instructed the bank to grant credit to the borrowers and undertook full liability for repayment; the broader waiver of defenses did not alter the mandate characterization.
