Kernrechtsfrage
Whether the appellant had party status in the complaint proceedings against the health professional and institutions.
Extrahierter Entscheid
He had no party status because the children were under a representation curatorship; only the curator could act for their interests in relation to the ordered expertise.
Extrahierte Begründung
The cantonal court's view that parental authority was limited by Art. 306(3) CC for matters covered by the curatorship was not arbitrary.
