Kernrechtsfrage
Whether the cantonal court correctly withdrew the appellant's extended parental authority and ordered guardianship for the adult son.
Extrahierter Entscheid
The withdrawal was upheld because the son's best interests clearly required remaining in Switzerland under a neutral guardian, rather than being placed under the appellant's extended parental authority.
Extrahierte Begründung
The court accepted the factual findings that the son was well integrated in Switzerland, had stable care, work, and social support, and that removal to Canada would seriously disturb his well-being. The appellant's objections attacked the evidence only in an appellatory manner and did not show arbitrariness or a violation of federal law.
