Kernrechtsfrage
Whether the administrative law appeal was admissible against the refusal to renew the residence permits
Extrahierter Entscheid
The administrative law appeal was inadmissible because federal law conferred no entitlement to the requested residence permit renewal.
Extrahierte Begründung
Under Art. 100(1)(b) OG and Art. 4 ANAG, residence permits are generally issued at the authority's discretion unless a specific federal-law or treaty-based right exists; none was shown.
