Kernrechtsfrage
Whether the public-law appeal was admissible in an immigration family-reunification case under Art. 83 lit. c ch. 2 BGG.
Extrahierter Entscheid
The appeal was admissible because the son had, in principle, a reunification claim under the old ANAG at the time of the application.
Extrahierte Begründung
For standing and admissibility, the relevant date was the application date, when the son was still under 18 and could invoke Art. 17 para. 2 ANAG.
