Question juridique clé
Admissibility of public-law appeal despite Art. 83 let. c ch. 2 LTF
Solution extraite
The appeal was admissible because the father could invoke Art. 8 ECHR, which could in principle give a right to reunification for his minor daughter.
Motifs extraits
Although Art. 44 LEtr is discretionary, the appellant had a durable residence right in Switzerland through marriage to a Swiss citizen and maintained an effective family relationship with his daughter, so Art. 8 ECHR opened the way to a public-law appeal.
