Kernrechtsfrage
Whether the cantonal court had to order further evidence on custody and parental authority despite existing expert reports.
Extrahierter Entscheid
No further evidentiary measures were required because the file already allowed the court to assess the child’s interests.
Extrahierte Begründung
The inquisitorial rule does not relieve the parties of cooperation, and the court may refrain from further investigations when the existing evidence suffices. The mother did not request new expert evidence below, and the alleged new facts were either already considered or inadmissible on appeal.
