Kernrechtsfrage
Whether the appeal was admissible and the father had standing regarding the son's reunification claim.
Extrahierter Entscheid
The appeal was admissible because the son had, in principle, a statutory reunification right under the former ANAG at the time of the application.
Extrahierte Begründung
Under the transitional rule, the former law applied. Since the son was under 18 when the application was filed, a reunification entitlement in principle existed; constitutional family-life arguments were not needed.
