Questione giuridica chiave
Whether the public-law appeal was admissible under Art. 83 lit. c ch. 2 and 5 LTF
Decisione estratta
The appeal was admissible insofar as the appellant plausibly relied on Art. 50(1)(b) LEtr; it was inadmissible only to the extent based on Art. 30 LEtr.
Motivazione estratta
A sustainable claim to a permit is enough to avoid the exclusion clause; the merits of that claim are examined later.
