Kernrechtsfrage
Whether the public law appeal was admissible against the refusal to renew the residence permit.
Extrahierter Entscheid
The appellant had no enforceable right to renewal, so the public law appeal was inadmissible.
Extrahierte Begründung
Her spouse had only an annual residence permit and no durable right of presence; therefore neither federal law nor the ECHR conferred a right to the permit.
