Question juridique clé
Admissibility of the public law appeal in an immigration permit case
Solution extraite
The appeal was admissible because the appellant, as a Swiss citizen, could plausibly invoke a family reunification right under Art. 42 AuG; the children's age is assessed at the time of filing the reunification request.
Motifs extraits
A potential entitlement suffices for standing. The later reaching of majority by one child did not matter because he was still a minor when the request was filed.
