Question juridique clé
Whether the federal appeal was admissible in a foreigner-law matter without a potential entitlement to a permit.
Solution extraite
The appellant did not show a potential right to a residence permit; admissibility could be left open because only constitutional grievances were invoked.
Motifs extraits
Under Art. 83 let. c ch. 2 LTF, ordinary public-law appeal is excluded absent a potential entitlement; however, constitutional complaints can still be examined for formal rights violations.
