Kernrechtsfrage
Whether the complaint was admissible based on a right to family reunification.
Extrahierter Entscheid
The complaint was admissible in principle because the son was still under 18 when the request was filed and the father could invoke Art. 17(2) ANAG, Art. 8 ECHR and Art. 13 BV.
Extrahierte Begründung
A legal entitlement exists only where a special federal rule or treaty right applies; for minor children of settled parents, Art. 17(2) ANAG can confer such a right.
