Kernrechtsfrage
Whether the public-law appeal was admissible despite Art. 83 lit. c ch. 2 BGG.
Extrahierter Entscheid
The appeal was admissible because the Swiss spouse had a principled right to family reunification under Art. 42 AuG and Art. 8 ECHR.
Extrahierte Begründung
A Swiss citizen spouse of an eligible foreigner has a statutory and convention-based claim, so the exception to inadmissibility did not apply.
