Questão jurídica principal
Whether the revocation of the settlement permit under former ANAG Art. 9(4)(a) was lawful.
Decisão extraída
Yes. The appellant had knowingly concealed essential facts to obtain and keep residence rights; the permit was therefore obtained by deception.
Fundamentação extraída
The sequence of marriages, separation, and family reunification requests showed a planned use of the marriage to secure residence. The court held that the appellant knew relevant facts and withheld them; had the authorities known the true situation, the settlement permit would not have been granted.
