Question juridique clé
Whether the public-law appeal was admissible despite the general exclusion rule for residence permits
Solution extraite
The appellant plausibly invoked a statutory entitlement under Art. 50 AuG, so the appeal was admissible.
Motifs extraits
For admissibility it suffices that the claimed right is argued in a tenable manner; whether the right exists and was violated belongs to the merits.
