Questione giuridica chiave
Whether the plaintiff is personally liable to the defendant under trust liability for failing to warn against the proposed tax-optimization transaction.
Decisione estratta
No trust liability arises on these facts because the defendant's protected trust arose from her contract with C. AG, not from any personal assurance by the plaintiff.
Motivazione estratta
Where a contract already governs the relationship, trust liability is exceptional and subsidiary. The defendant had contractual remedies against C. AG; no facts showed that the plaintiff personally assumed responsibility for performance or solvency.
