Question juridique clé
Whether the federal appeal satisfied the reasoning requirements of Art. 42 and Art. 108 BGG.
Solution extraite
The appeal did not engage with the decisive reasoning of the lower courts and therefore lacked sufficient substantiation.
Motifs extraits
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.
