Question juridique clé
Admissibility of the public-law appeal in an immigration matter without a statutory right to a permit
Solution extraite
The appeal was admissible because the mother, as a Swiss citizen, could invoke a principle-based right to her minor son's reunification and Article 8 ECHR.
Motifs extraits
A Swiss citizen has, under the case law, a claim to the child's residence permit when the child is under 18 and lives with the parent; therefore the bar in Art. 83 lit. c Ziff. 2 BGG did not apply.
