Kernrechtsfrage
Whether the appeal in public law matters was admissible despite the absence of a clear residence-permit entitlement.
Extrahierter Entscheid
No admissible public-law appeal lay because the appellant could not plausibly show an entitlement to a residence permit.
Extrahierte Begründung
Under Art. 83 lit. c ch. 2 BGG, such appeals are excluded unless a federal or treaty-based right to a permit exists. Art. 50 AuG could not create a new claim here because the original case had been decided under the former law and the matter was a closed factual situation after the marriage breakdown.
