Question juridique clé
Whether the public law appeal was admissible in the absence of a statutory or treaty-based right to the requested residence permit.
Solution extraite
No enforceable right existed, so the public law appeal was barred by the Federal Supreme Court Act.
Motifs extraits
After the divorce, the appellant could no longer rely on family reunification. He could not derive a residence right from the Constitution or Article 8 ECHR because he did not show a sufficiently close and effective dependency relationship with his father or siblings.
