Question juridique clé
Whether the appeal in public law matters was admissible despite the immigration nature of the case.
Solution extraite
The appeal was admissible because the appellant could potentially derive a right to a residence permit from family life under Article 8 ECHR and Article 42 LEtr.
Motifs extraits
The existence of a potentially applicable statutory and conventional right means the bar of Art. 83 let. c ch. 2 LTF does not apply at the admissibility stage.
