Kernrechtsfrage
Whether the planned works could be provisionally prohibited as unlawfully imposed on the tenants.
Extrahierter Entscheid
The cantonal court's assessment was not arbitrary: the works were largely maintenance-related and could very likely be imposed on the tenants.
Extrahierte Begründung
The testimony and expert report made it plausible that the chute columns and piping were deteriorated and that delaying replacement risked water damage. The bathroom and kitchen works were closely linked to the piping replacement and were not excessive.
