Question juridique clé
Whether the manager gravely breached the investment mandate and could rely on the contractual liability disclaimer.
Solution extraite
The manager breached the mandate by shifting the portfolio far beyond the agreed balanced profile; this amounted to gross negligence, so the disclaimer did not apply.
Motifs extraits
The mandate required a cautious, balanced investment policy with only limited risk-taking. The manager instead increased equity exposure to over 70% and concentrated risk heavily in a few positions, contrary to instructions and to the duty to safeguard the client's interests.
