Questione giuridica chiave
Whether the plaintiff could invoke the simulated lease against the defendant and acquire ownership and contractual claims by assignment.
Decisione estratta
Yes. The defendant could not oppose simulation against the plaintiff, because the plaintiff had acquired the claims and ownership in good faith and the defendant was liable for the apparent legal situation created by the parties.
Motivazione estratta
The lower court's findings bound the Federal Supreme Court. The plaintiff relied on the signed lease contract and the parties' representations, not merely on the lessor's statements. The defendant helped create the appearance that the vehicle belonged to X. AG, so he could not invoke simulation against the assignee.
