Key legal question
Whether the bank was liable for omitting adverse fourth-quarter 1985 information from the bond prospectus.
Extracted holding
The bank was not liable because, on the facts found, it had taken the usual verification steps and had no alarm signals requiring further investigation or disclosure.
Extracted reasoning
Liability under Art. 1156(3) CO is fault-based; the plaintiff had to prove a breach of due diligence. The cantonally found facts showed reliance on counsel and the auditor, no obvious red flags, and no proof that the bank could have discovered the negative trend with required diligence.
