Questão jurídica principal
Whether the fiduciary was contractually obliged to verify the validity of the investment guarantee and liable for not warning the investor.
Decisão extraída
Yes. Given the mandate, the surrounding negotiations, and the relationship of trust created, the investor could in good faith expect the fiduciary to warn him and to verify the guarantee.
Fundamentação extraída
The court found a mandate and irregular deposit relationship, analogized the fiduciary’s position to a bank’s, and held that the contractual context and conduct during negotiations created a duty of diligence and loyalty under Art. 398 CO.
