Kernrechtsfrage
Whether the refusal to renew the residence permit was lawful because the marriage was entered into to circumvent immigration rules.
Extrahierter Entscheid
Yes. The court held that the factual findings supported a sham marriage and therefore no entitlement to renewal existed under the applicable law.
Extrahierte Begründung
The cantonal court could rely on concrete indicia: payment of CHF 30,000 for the marriage, contradictory statements, lack of genuine cohabitation, concealment from adult children, and the applicant's prior repeated attempts to regain residence status. These findings were not rebutted.
