Key legal question
Whether the settlement permit could be revoked for false statements or concealment of material facts.
Extracted holding
Yes. X. knowingly concealed material facts to obtain the permit, so the statutory revocation ground was met.
Extracted reasoning
His family history, prior relationship with his present wife, and continued formal marriage to the first wife showed a deliberate plan to secure residence rights. Disclosure of the omitted facts would have prompted closer scrutiny and led to refusal of the settlement permit.
