Question juridique clé
Whether the federal public-law appeal was admissible under Art. 83 lit. c ch. 2 LTF despite the permit refusal.
Solution extraite
The appeal was admissible because the appellant invoked personal reasons under Art. 50 LEtr, so the existence of a federal-law entitlement had to be examined on the merits.
Motifs extraits
Admissibility does not depend on whether Art. 50 LEtr is ultimately satisfied; that question belongs to the merits.
