Questione giuridica chiave
Whether the lease contained a sufficiently clear special agreement making accessory charges payable by the tenant.
Decisione estratta
No. The contract fixed monthly advances and a final settlement, but did not specify which accessory charges were owed; payment of advances did not replace the missing agreement.
Motivazione estratta
Under Art. 257a(2) CO accessory charges are borne by the tenant only if specially agreed. The contract did not describe the charges clearly and specifically, and the appellant's factual assertions were inadmissible.
