Questione giuridica chiave
Whether attorney's fees from prior rent litigation can be claimed as damages under Art. 97 CO despite the cantonal rule excluding costs and party compensation in tenancy disputes.
Decisione estratta
No. Where procedural law excludes or regulates party costs, a separate damages action under Art. 97 CO cannot be used to recover those same expenses.
Motivazione estratta
Civil liability cannot circumvent special procedural cost rules; this applies equally to former cantonal procedure and the CPC. Only fees outside the scope of recoverable procedural costs, or expenses caused by procedural bad faith under Art. 115 CPC, may be claimed separately.
