Kernrechtsfrage
Whether the settlement permit could be revoked for knowingly concealing material facts.
Extrahierter Entscheid
Yes. He obtained the permit by withholding that his marriage was only formal, that he had long lived apart from his Swiss spouse, and that he had a long-standing relationship and four children in Turkey.
Extrahierte Begründung
The court found multiple decisive omissions in the permit process. Under the established doctrine, a permit may be revoked where the applicant knowingly withholds facts that matter for the decision and thereby misleads the authority about the real purpose of the application.
