Question juridique clé
Whether the public law appeal was admissible despite the lack of an enforceable entitlement to renewal of the residence permit.
Solution extraite
No admissible public law appeal lay because the appellant had no federal-law or treaty-based entitlement to renewal and the challenge to expulsion/removal was excluded.
Motifs extraits
Under Art. 83 lit. c Ziff. 2 and 4 BGG, admissibility requires a legally protected right to the permit; the appellant had neither a settlement permit nor another secured right.
