Kernrechtsfrage
Whether the administrative law appeal against the refusal to extend the residence permit was admissible without a federal entitlement to the permit.
Extrahierter Entscheid
No admissibility, because the applicant had no enforceable right to the requested residence permit.
Extrahierte Begründung
Residence permits are discretionary absent a specific federal or treaty-based entitlement; none existed here, so the ordinary administrative law appeal was barred.
