Questione giuridica chiave
Whether the tenant extinguished the rent debt within the statutory grace period under Art. 257d CO
Decisione estratta
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.
Motivazione estratta
Only payment within the warning period counts; compensation must be invoked before expiry of the comminatory period, which the tenant failed to do.
