Question juridique clé
Admissibility of the public law appeal under Art. 83 lit. c ch. 2 LTF despite foreigner law
Solution extraite
The appeal was admissible because the appellant was still formally married to a Swiss citizen, so a statutory right under Art. 7 LDDS existed in principle.
Motifs extraits
For admissibility, it is enough that the marriage formally subsists; whether the right has lapsed through abuse of rights is a merits question, not an admissibility question.
