Question juridique clé
Whether the public-law appeal was admissible despite the immigration-law exclusion rule
Solution extraite
The appeal was admissible because a settlement permit could, in principle, have been acquired under the former law before the divorce, which would also support the residence permit claim.
Motifs extraits
Under the applicable former ANAG rules, a foreign spouse may have an entitlement to a settlement permit after five years of lawful and uninterrupted marriage; the existence of a potential entitlement makes the federal appeal route available.
