Question juridique clé
Whether the public-law appeal was admissible under Art. 50 AuG and related rules
Solution extraite
The appeal was admissible insofar as the appellants relied on a plausible entitlement under Art. 50 AuG; the subsidiary constitutional complaint was inadmissible.
Motifs extraits
A plausible residence-permit entitlement under Art. 50 AuG opens the public-law route. Claims based on Art. 30 AuG do not create an entitlement and cannot be pursued by this avenue.
