Questione giuridica chiave
Whether the administrative law appeal against refusal of a residence/settlement permit was admissible
Decisione estratta
The appeal was admissible because the spouse of a Swiss citizen can in principle invoke a federal statutory right under Art. 7 LDDS; whether that right is lost through abuse concerns the merits.
Motivazione estratta
The existence of a potentially enforceable right under federal law makes the remedy available; the abuse-of-right question does not affect admissibility.
