Key legal question
Whether the administrative law appeal was admissible against refusal to renew the residence permit.
Extracted holding
The appeal was admissible because the applicant, as spouse of a Swiss citizen, could invoke Art. 7(1) LDDS; whether the right was extinguished by abuse was a merits question.
Extracted reasoning
A statutory entitlement existed in principle, so federal review was available; the limits of that entitlement fell to be examined on the merits, not at admissibility stage.
