Kernrechtsfrage
Admissibility of the public law appeal and of the subsidiary constitutional complaint
Extrahierter Entscheid
The public law appeal was admissible because the claim could potentially arise under federal law; the subsidiary constitutional complaint was therefore inadmissible.
Extrahierte Begründung
Whether Art. 49 or 50 LEtr granted a right to renewal was a merits question, not a jurisdictional one, so Art. 83(c)(2) LTF did not bar the appeal.
