Kernrechtsfrage
Whether the appeal in public law matters was admissible despite the subsidiary constitutional complaint
Extrahierter Entscheid
Because the appellant invoked a possible entitlement under Art. 50 AuG, the appeal in public law matters was in principle available; there was no room for a subsidiary constitutional complaint.
Extrahierte Begründung
A claimed statutory right to a permit opens the ordinary constitutional-law appeal route under the BGG.
