Questão jurídica principal
Whether the settlement permit could be revoked for having been obtained by false statements or concealment of material facts.
Decisão extraída
Yes. The permit was obtained by knowingly concealing the true family situation and maintaining only a formal marriage to obtain residence status.
Fundamentação extraída
The timeline showed a planned course of conduct: continued relationship with the Serbian wife, birth of a child during the Swiss marriage, and concealment of these facts from the authorities. The authorities would not have granted the permit had they known the real situation.
