Kernrechtsfrage
Whether the appellant was entitled to renewal of his residence permit based on marriage to a Swiss citizen.
Extrahierter Entscheid
The statutory entitlement failed because the marital community was no longer genuinely lived and reliance on the marriage was abusive.
Extrahierte Begründung
The court accepted the lower court's factual findings that the spouses had been separated since February 2006 and that multiple indicia showed no real resumption of cohabitation; Art. 42 AuG requires living together unless an exception applies, and Art. 51 AuG bars abusive reliance on marriage.
