Questão jurídica principal
Whether the federal administrative appeal was admissible against refusal to renew the residence permit
Decisão extraída
The appeal was admissible because the applicant invoked a potential right under federal law and treaty provisions; whether that right had lapsed was a merits question.
Fundamentação extraída
Art. 7 LDDS gives the foreign spouse of a Swiss citizen a right to a residence permit, so the refusal could be reviewed. The possible loss of that right through abuse of rights did not affect admissibility.
