Questione giuridica chiave
Whether the public law appeal against the cantonal judgment was admissible
Decisione estratta
Yes, because the appellant was married to a Swiss national and could invoke a statutory entitlement to a residence permit.
Motivazione estratta
Under Art. 83(c)(2) LTF, the remedy is excluded only if no federal or international right to the permit exists. A formal marriage to a Swiss spouse is sufficient for admissibility.
