Lessor Liability for Third-Party Disturbance Justifying Rent Reduction

A lessee, during the term of a lease, claimed a reduction in rent alleging that the leased premises were partially unusable due to damage caused by a third party, an issue the lessor had failed to remedy despite notification, leading the lower court to grant the rent reduction based on the principle that a lessor's failure to ensure peaceful enjoyment allows the lessee to seek indemnification, including a rent reduction. The high court upheld the decision, reasoning that the obligation to guarantee peaceful enjoyment under the lease contract is one of result, meaning the lessor is liable for any disturbance caused by a third party unless they can prove the disturbance was due to a cause beyond their control, which was not established here, thus justifying the judicial reduction of rent until the disturbance ceased.
