Kernrechtsfrage
Whether alleged loss of access to the leased premises excused payment of rent under Art. 82 CO and supported an evidentiary complaint under Art. 8 CC.
Extrahierter Entscheid
The tenant could not invoke non-performance because the landlord had continuously kept the premises available and any inability to use them stemmed from the tenant's own decision to let its subsidiary use the premises.
Extrahierte Begründung
Art. 8 CC concerns burden of proof, but the disputed fact was immaterial to the rent claim. In a synallagmatic contract, a debtor cannot rely on non-performance where it has itself made performance impossible; rent is due for making the premises available, not for actual use.
