Kernrechtsfrage
Whether the residence permit had to be renewed under Art. 42 and Art. 50 AuG after marital separation.
Extrahierter Entscheid
No. The couple had lived separately since 1 January 2007, and the marriage-based entitlement had therefore ceased; the three-year requirement of Art. 50(1)(a) AuG was not met.
Extrahierte Begründung
The shared household lasted only about 20 months in Switzerland. Even counting additional time would not reach three years, and the statutory threshold is absolute.
