Questione giuridica chiave
Whether the administrative law appeal was admissible against the refusal to renew the residence permit.
Decisione estratta
The appeal was inadmissible because no federal law or treaty conferred a right to renewal.
Motivazione estratta
The appellant could not rely on Art. 17(2) LSEE because his spouse lacked a settlement permit, and he could not derive a right from Art. 8 ECHR since no family member had a secured right of presence in Switzerland.
