Kernrechtsfrage
Whether the appeal was admissible despite the general exclusion in immigration matters.
Extrahierter Entscheid
The appeal was admissible because a potential statutory entitlement under Art. 42 in connection with Art. 126(3) AuG existed at the time of the request.
Extrahierte Begründung
A potential claim suffices for standing; the son's later majority no longer mattered for admissibility because the request was filed while he was still a minor.
