Questione giuridica chiave
Whether the public-law appeal was admissible against refusal to renew the residence permit.
Decisione estratta
The appeal was admissible only to the extent that the appellant could invoke a protected family-life claim through her child; it was otherwise inadmissible for lack of an entitlement.
Motivazione estratta
Under Art. 83 lit. c ch. 2 BGG, the remedy is unavailable where no statutory or treaty right exists. A spousal claim failed because the marriage was no longer actually lived. A child-based claim under Art. 8 ECHR and Art. 13 BV remained possible because the child had settled status and the mother exercised custody.
