Question juridique clé
Whether the appeal was admissible despite the general bar on challenges to residence permit refusals.
Solution extraite
The appellant plausibly invoked a potential entitlement under Art. 50(1)(b) AuG, so the appeal was admissible.
Motifs extraits
For admissibility, it suffices to show a potentially cognizable claim; the substantive fulfilment of the conditions is examined on the merits.
