Kernrechtsfrage
Whether the 250,000 CHF mortgage note extinguished the causal loan claim by novation under Art. 855 CC or was delivered as fiduciary security.
Extrahierter Entscheid
The note was delivered as fiduciary security; the causal claim was not extinguished by novation.
Extrahierte Begründung
The loan contract expressly listed the note under 'security'; the loan and note were subject to the same security regime; the note debtors and causal debtors were not identical; and the contractual structure showed an intention to secure, not to replace, the loan claim.
