Questione giuridica chiave
Whether the public-law appeal against the residence-permit refusal was admissible.
Decisione estratta
The appeal was admissible because the appellant could invoke a treaty-based entitlement under the Free Movement Agreement.
Motivazione estratta
As an EU national, he had a principled right to a residence permit under the FZA; thus the statutory bar in Art. 83 lit. c ch. 2 BGG did not apply.
