Kernrechtsfrage
Whether the settlement permit had to be revoked for concealment of essential facts under the ANAG.
Extrahierter Entscheid
Yes. The applicant knowingly withheld materially relevant information about his extramarital relationship and two children, justifying revocation.
Extrahierte Begründung
The existence of minor children and a new family is objectively relevant to the permit decision. The applicant had a duty to disclose these facts; the cantonal authorities were entitled to infer intentional concealment and abuse of the marital relationship to reach the five-year threshold.
