Question juridique clé
Whether the public law appeal against the refusal to renew the residence permit was admissible.
Solution extraite
It was inadmissible because no enforceable right to the permit existed under federal law or international law.
Motifs extraits
After the divorce and separation, no entitlement could be derived from Art. 17 ANAG. The appellant also could not rely on Art. 8 ECHR, since he was an adult without children, not dependent on close relatives with secure residence status, and not sufficiently integrated to invoke private-life protection.
