Questione giuridica chiave
Whether the appeal in public law matters was admissible and the subsidiary constitutional complaint could be heard.
Decisione estratta
The appellant asserted a potentially arguable right under Art. 50 AuG, so the public law appeal was admissible; the subsidiary constitutional complaint was inadmissible.
Motivazione estratta
A potentially existing claim is sufficient for standing. Because the ordinary appeal was available, the subsidiary constitutional complaint was excluded.
