Kernrechtsfrage
Whether the federal appeal satisfied the reasoning requirements of Art. 42 and Art. 108 BGG.
Extrahierter Entscheid
The appeal did not engage with the decisive reasoning of the lower courts and therefore lacked sufficient substantiation.
Extrahierte Begründung
The appellant only disputed the expert report issue and did not meaningfully address the findings on the imputed rental value, the refused under-occupancy deduction, or the cost ruling; this failed the duty of focused reasoning.
