Kernrechtsfrage
Whether the complaint was admissible despite the general exclusion for residence-permit cases.
Extrahierter Entscheid
The complaint was admissible because the appellant invoked a possible statutory entitlement under Article 50 AuG.
Extrahierte Begründung
A public-law appeal is excluded only where no right exists under federal law or international law; the asserted post-marital entitlement had to be examined on the merits.
