Kernrechtsfrage
Whether the public-law appeal was admissible despite the immigration exclusion rule.
Extrahierter Entscheid
The appeal was admissible because the applicant could in principle derive a right to a residence permit from Art. 7 ANAG as a spouse of a Swiss citizen.
Extrahierte Begründung
The marriage formally still existed, so the refusal concerned the merits, not admissibility; alleged exceptions or abuse of rights are assessed substantively.
