Kernrechtsfrage
Whether the public-law appeal against the cantonal judgment was admissible as a remedy for residence/settlement permit refusal
Extrahierter Entscheid
The appeal was not admissible because no federal statute or treaty granted a right to renewal of the residence permit or to a settlement permit.
Extrahierte Begründung
Without a legal entitlement to the immigration benefit sought, the matter could not be brought as a public-law appeal on the merits.
