Question juridique clé
Whether the federal public-law appeal was admissible despite the old title and lack of an independent entitlement to a residence permit
Solution extraite
The appeal was admissible because the contested revocation or declaration that the permit no longer existed affected the appellant's legal position.
Motifs extraits
Although the appellant had no treaty-based right to the permit, the permit was formally valid until 2011; revocation of an existing permit is reviewable under Art. 83 let. c ch. 2 LTF a contrario.
