Kernrechtsfrage
Whether the cantonal court had to take additional evidence and re-hear the child after remittal
Extrahierter Entscheid
No. The remittal bound the cantonal court to the Supreme Court's legal instructions, but it was not required to take further evidence absent changed circumstances; a renewed child hearing was unnecessary.
Extrahierte Begründung
The court held that the investigation duty was satisfied: the child's continued opposition was already established, the higher age of the child was a matter of legal assessment, and no new facts required reopening evidence.
