Kernrechtsfrage
Whether the mother could invoke an enforceable right to renewal of the residence permit under Art. 7 ANAG
Extrahierter Entscheid
Yes, the mother had standing to invoke Art. 7 ANAG because she remained formally married to a Swiss citizen and had continuously lived in Switzerland; however, the substantive claim failed because the marriage had already irretrievably broken down before five years elapsed.
Extrahierte Begründung
A formal marriage can suffice for admissibility, but the right under Art. 7 ANAG is lost by abuse of rights once there is objectively no realistic prospect of resuming marital cohabitation before the five-year threshold is reached.
