Question juridique clé
Whether the complaint was admissible despite the general exclusion for residence-permit cases.
Solution extraite
The complaint was admissible because the appellant invoked a possible statutory entitlement under Article 50 AuG.
Motifs extraits
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.
