Kernrechtsfrage
Whether the bank breached duties of information or diligence in connection with the bond placements and secondary-market purchases.
Extrahierter Entscheid
On the established facts, the bank’s conduct did not justify liability; in particular, no adequate causal link was shown between any alleged omissions and the investor’s purchases.
Extrahierte Begründung
The investor remained willing to invest even after learning of the issuer’s difficulties and later sought to raise new funds for the same project. This excluded the required hypothetical causal link. The court also held that the bank had no enforceable special duty to warn in the circumstances found by the cantonal court.
