Supreme Court allows prior rent judgment to be used as evidence for future rent reduction claims based on property defects.

The Supreme Court permitted the use of a previous judgment regarding rent amounts as evidence in a subsequent dispute concerning rent reduction due to property defects. The tenant argued that the prior ruling established the baseline for reasonable rent, while the landlord contended that property conditions had changed since the earlier decision. The court ruled that the prior judgment remains relevant evidence to determine if the current rent exceeds the reasonable amount given the existing state of the property.
