Question juridique clé
Whether the public law appeal was admissible despite the immigration context and the obsolete label 'recours de droit public'.
Solution extraite
The public law appeal was admissible to the extent the appellant could plausibly rely on a right under Art. 50 LEtr and Art. 8 ECHR; the subsidiary constitutional appeal was therefore inadmissible.
Motifs extraits
A potential entitlement under Art. 50 LEtr removes the Art. 83(c)(2) obstacle; claims based on Art. 30 LEtr alone do not. The Art. 8 ECHR privacy argument also justified admissibility.
