Kernrechtsfrage
Whether the settlement permit could still be revoked for false statements or concealment of material facts despite the authorities' prior knowledge of suspicions of a sham marriage.
Extrahierter Entscheid
No. Because the authorities already knew the relevant indications when they granted the settlement permit, a later revocation based on those same known circumstances was excluded; later events did not retroactively prove a sham marriage.
Extrahierte Begründung
The canton had granted the permit without further inquiry despite existing indications. The later divorce, remarriage, child, and family reunification request occurred after the permit grant and did not allow a retroactive inference that the earlier marriage had been purely formal.
