Questione giuridica chiave
Whether P. SA acted as direct representative of Y. for the Lombard credit relationship, allowing claims against Y., Y.a., and R.
Decisione estratta
P. SA did not act as a direct representative of Y.; the credit relationship was formed with P. SA itself, so the bank could not claim repayment from Y., Y.a., or R. on that basis.
Motivazione estratta
The bank had dealt with P. SA as fiduciary and contractual counterparty; the facts supported at most indirect representation, not direct representation. The appellant also failed to challenge the alternative finding of contradictory conduct, which independently upheld the dismissal.
