Question juridique clé
Whether the public-law appeal was admissible despite the general exclusion in immigration matters.
Solution extraite
The appeal was admissible because the appellant, as the spouse of a Swiss citizen whose marriage still formally existed, had a prima facie statutory claim to a residence permit under former law.
Motifs extraits
The admissibility question depended on whether a legal entitlement existed. The existence of possible abuse or statutory exceptions concerned the merits, not standing.
