Key legal question
Whether the appellant had a right to renewal of the residence permit under Art. 7 LDDS despite the marital separation.
Extracted holding
The right under Art. 7 LDDS was not available because the appellant relied on a marriage that existed only formally and was invoked solely to remain in Switzerland.
Extracted reasoning
The evidence showed a short common household, long separation, contradictory statements, and no credible reconciliation; this amounted to abuse of rights.
