Key legal question
Whether the public law appeal was admissible for the family reunification claim and the subsidiary constitutional complaint could still be heard.
Extracted holding
The public law appeal was admissible because the appellant had a principled entitlement under Art. 17(2) ANAG; the subsidiary constitutional complaint was inadmissible.
Extracted reasoning
Minor children under 18 at the relevant filing date may invoke the ANAG family reunification right; because federal law provided an arguable claim, Art. 83 lit. c no. 2 BGG did not bar the appeal, and no room remained for a subsidiary constitutional complaint.
