Assignment of Rights: Implied Warranty in Voluntary Transfer

The case concerns a dispute over the validity of an assignment of rights, where the assignee argued that the assignor had guaranteed the existence and quality of the assigned rights, even though the contract was silent on this point, relying on implied warranty under general law. The court rejected the appeal, reasoning that in a voluntary assignment of rights, the assignor is only liable for the existence of the right at the time of transfer unless expressly stipulated otherwise; absent explicit contractual provision or a specific legal exception, the silence of the contract regarding warranty against eviction or defects implies no such guarantee was intended, meaning the assignor is not responsible for the subsequent non-existence or loss of the right.
