Question juridique clé
Whether the public-law appeal was admissible despite the immigration-law exception.
Solution extraite
The appeal was admissible because the appellant could rely on a statutory claim under former ANAG provisions.
Motifs extraits
Although the case concerned a residence permit, the appellant had been in Switzerland continuously for more than five years on a legal basis linked to marriage with a Swiss citizen, so Art. 83 lit. c ch. 2 BGG did not bar the remedy.
