Questione giuridica chiave
Admissibility of the public-law appeal despite the immigration exception
Decisione estratta
The appeal was admissible because the applicant could arguably claim a right under Art. 50 LEtr; whether he actually met the conditions was a merits question.
Motivazione estratta
The asserted right was not manifestly untenable, so Art. 83(c)(2) LTF did not bar the appeal.
