Questione giuridica chiave
Whether the rental reduction under Art. 259d OR was limited to the months during which rent was deposited.
Decisione estratta
No. The reduction runs from the landlord's knowledge of the defect until its remedy, but can only be claimed for periods in which rent was actually paid or deposited.
Motivazione estratta
The court held that Art. 259d OR does not support limiting the reduction to the deposit period. However, the tenant cannot claim a reduction for months in which no rent was paid at all, because there is then no rent to reduce.
