Questione giuridica chiave
Whether the CHF 1,954,636.13 payment had a valid contractual basis or was unduly paid
Decisione estratta
The payment was based on a distinct settlement agreement concluded by the parties when the loan was terminated, so it was not without cause.
Motivazione estratta
The cantonal court found the parties had a common actual intent to end their mutual obligations definitively against payment of the capital and agreed indemnities. That factual finding bound the Federal Court and excluded a restitution claim.
