Question juridique clé
Whether the appeal was admissible despite Article 83(c)(2) LTF
Solution extraite
The appeal was admissible because the appellant plausibly relied on Article 50(1)(b) LEtr as a potential entitlement to remain in Switzerland.
Motifs extraits
A colorable claim under Article 50(1)(b) LEtr suffices for admissibility; whether the conditions are actually met is a merits question.
