Key legal question
Whether the appeal in public law matters was admissible based on Art. 50 AuG.
Extracted holding
The appeal was admissible only insofar as the appellant plausibly relied on Art. 50 AuG; otherwise only subsidiary constitutional complaint was available.
Extracted reasoning
Art. 50 AuG can found a right to renewal after dissolution of the family union, whereas Art. 30(1)(b) AuG is a discretionary hardship exception without a claim.
