Questione giuridica chiave
Whether the administrative law appeal was admissible against the refusal to renew the residence permit.
Decisione estratta
No federal-law or treaty-based entitlement existed, so the appeal was excluded.
Motivazione estratta
The spouses were living separately, had cohabited for less than five years, and there was no concrete prospect of reconciliation; therefore Art. 17(2) ANAG gave no claim to renewal.
