Kernrechtsfrage
Whether the tenant extinguished the rent debt within the statutory grace period under Art. 257d CO
Extrahierter Entscheid
The tenant did not pay the full arrears in time; the rent for April 2013 was paid after the deadline and the alleged set-off claims were not invoked in time.
Extrahierte Begründung
Only payment within the warning period counts; compensation must be invoked before expiry of the comminatory period, which the tenant failed to do.
