Questão jurídica principal
Whether the cantonal court's finding of a severe defect in the leased premises was arbitrary under Article 9 of the Constitution.
Decisão extraída
No. The Federal Court held that, given the unresolved fire-safety deficiencies and the safety implications, the cantonal court could find a serious defect without arbitrariness.
Fundamentação extraída
The complaint merely opposed the cantonal assessment with a different view. The landlord did not show that the factual findings were manifestly untenable or clearly contradicted by the record.
