Question juridique clé
Whether the refusal of an on-site inspection violated the right to be heard or was arbitrary.
Solution extraite
The complaint was inadmissible insofar as it asserted a violation of the right to evidence; any arbitrariness challenge was insufficiently substantiated.
Motifs extraits
The right to evidence under Art. 8 ZGB had to be raised by appeal, and the arbitrariness complaint did not engage with the cantonal court's reasoning or the evidentiary record.
