Kernrechtsfrage
Whether a public law appeal was admissible against the non-renewal of the residence permit
Extrahierter Entscheid
No; the applicant had no enforceable entitlement to renewal because the family-based right had lapsed with separation and definitively with the divorce.
Extrahierte Begründung
Without a current legal entitlement, the public law appeal was excluded; the prior cantonal non-entry ruling had not been challenged.
