Questione giuridica chiave
Whether the settlement permit could be revoked for obtaining it by knowingly concealing material facts.
Decisione estratta
Yes. The appellant had knowingly withheld essential information, so a revocation ground existed.
Motivazione estratta
The court accepted the lower court's factual findings that the appellant had pursued a planned scheme to obtain residence status and later bring his real family to Switzerland. That pattern, together with specific indications in the record, supported the finding of deliberate concealment of his extramarital family situation and children.
