Kernrechtsfrage
Whether the administrative appeal was admissible despite the general bar on foreign-police permit cases.
Extrahierter Entscheid
It was admissible because the son had a secure residence right in Switzerland, allowing the mother to invoke Article 8 ECHR.
Extrahierte Begründung
The child retained a settled right of residence; therefore the mother, as custodial parent, could derive an enforceable claim from family life protection.
