Kernrechtsfrage
Whether the federal public law appeal is admissible despite the foreigner-law exception.
Extrahierter Entscheid
The appeal is admissible because the appellant invoked a potentially enforceable right under Art. 50 AuG.
Extrahierte Begründung
A potential entitlement under Art. 50 AuG is sufficient for standing; whether the conditions are met belongs to the merits.
