Kernrechtsfrage
Whether the appellant was entitled to renewal of his residence permit based on marriage to a Swiss citizen
Extrahierter Entscheid
The marriage was only formally maintained and reliance on it was abusive; no entitlement to renewal existed.
Extrahierte Begründung
There were clear indications that no genuine marital life remained: the spouses had long been separated, divorce proceedings were pending, and the wife's statements and those of her siblings supported the view that the relationship had never functioned as a real shared life.
