Kernrechtsfrage
Whether the settlement permit could be revoked because it had been obtained by false statements or concealment of material facts.
Extrahierter Entscheid
Yes. The fraudulent procurement of the appellant's settlement permit was already finally established, so the revocation ground was met.
Extrahierte Begründung
The earlier cantonal decision on fraudulent acquisition was final and binding; the federal court would not revisit that issue.
