Kernrechtsfrage
Whether the constitutional complaint was admissible against the refusal to extend the residence permit
Extrahierter Entscheid
The complaint was inadmissible because no legally cognizable right to a permit extension was shown.
Extrahierte Begründung
A public-law appeal would require an enforceable right under Art. 83(c)(2) BGG; the applicant failed to show a continuing entitlement under Art. 43 AuG or a family-life claim under Art. 8 ECHR.
