Question juridique clé
Whether the public-law appeal was admissible despite the foreigner law exception.
Solution extraite
Yes, insofar as the appellant relied on a formal marriage to a Swiss citizen under Art. 7(1) LSEE; any request based only on cantonal discretion was inadmissible.
Motifs extraits
A formal marriage with a Swiss national suffices for standing under Art. 83(c)(2) LTF; discretionary residence claims remain excluded.
