Question juridique clé
Whether the public-law appeal was admissible despite the no-claim rule for residence permits
Solution extraite
The appeal was admissible for the father because he could invoke Article 8 ECHR through his Swiss minor son’s settled residence in Switzerland.
Motifs extraits
A foreign parent may rely on a constitutional or Convention-based claim when a Swiss child has a settled right of residence; the merits of the refusal are not part of admissibility.
