Kernrechtsfrage
Whether the administrative law appeal was admissible without a statutory or treaty-based entitlement to a residence permit.
Extrahierter Entscheid
The appeal was inadmissible because no federal-law or treaty-based right to the permit existed.
Extrahierte Begründung
Under the foreign nationals regime, residence permits are discretionary unless a special federal norm or treaty creates an enforceable entitlement. The father had no secure residence status and had been removed, so the family could not derive a claim from family reunification or from constitutional/ECHR guarantees.
