Question juridique clé
Whether the refusal to consent to renewal of the residence permit was lawful under Art. 50 AuG
Solution extraite
No important personal reasons were established that would require continued residence in Switzerland.
Motifs extraits
The alleged domestic violence was insufficiently substantiated and in any event not shown during the period of marital cohabitation; the husband's illness was known or foreseeable at marriage, so the later breakdown did not justify a renewed residence right.
