Question juridique clé
Whether the public-law appeal against refusal to renew the residence permit was admissible under Art. 7 ANAG
Solution extraite
Yes; because the formal marriage still existed, the appellant in principle had a statutory claim to renewal.
Motifs extraits
A merely separated but still formally existing marriage can found an enforceable right under Art. 7 ANAG; abuse of rights is a merits issue, not an admissibility issue.
