Questione giuridica chiave
Whether the federal appeal against refusal to renew the residence permit was admissible.
Decisione estratta
The appeal was inadmissible because no federal right to the permit renewal was shown.
Motivazione estratta
In immigration matters, administrative appeal is excluded where federal law grants no entitlement. The applicants failed to establish a right under Art. 8 ECHR, Art. 13 BV, or Art. 34 BVO, so there was no legally protected interest.
