Questione giuridica chiave
Whether agreement III was a form-free rescission under Art. 115 OR or a form-requiring amendment under Art. 12 OR
Decisione estratta
Agreement III extinguished the original land purchase contract in its entirety and was therefore valid without written or notarized form.
Motivazione estratta
A rescission agreement may end the whole contractual relationship form-free, even if the original contract required a special form, provided the contract no longer remains in force. The repayment condition was set outside the original synallagmatic exchange and merely regulated unwinding.
