Question juridique clé
Whether the federal appeal was admissible against refusal to renew the residence permit
Solution extraite
Because a formal marriage to a Swiss citizen still existed, the appellant could in principle invoke a statutory entitlement to a permit renewal; the appeal was therefore admissible on that point.
Motifs extraits
Under Art. 7(1) ANAG, the foreign spouse of a Swiss citizen has a right to a permit regardless of the material merits at the admissibility stage; the abuse-of-rights question belongs to the merits.
