Question juridique clé
Whether the public-law appeal was admissible despite the foreigner-law exclusion clause.
Solution extraite
The appeal was admissible because the appellant invoked a potentially enforceable right based on family life under the ECHR and Art. 43 LEtr.
Motifs extraits
A plausible right to renewal is sufficient at the admissibility stage; the merits decide whether the right actually exists.
