Kernrechtsfrage
Whether the appeal by A.________ Ltd and B.________ Ltd against the complaint chamber judgment was admissible despite not being addressees of that judgment
Extrahierter Entscheid
No. Only C.________ AG was bound by the judgment, so the other appellants lacked standing to challenge it.
Extrahierte Begründung
Under Art. 81(1)(a) LTF, only a person affected by the decision may appeal; the judgment addressed only C.________ AG.
