Questione giuridica chiave
Whether the public law appeal was admissible despite the foreigner-law exclusion clause, and whether the subsidiary constitutional appeal could be heard.
Decisione estratta
The appellant credibly invoked a potential entitlement under Art. 50 LEtr and Art. 8 ECHR, so the public law appeal was admissible; the subsidiary constitutional appeal was inadmissible.
Motivazione estratta
At the admissibility stage, a plausible legal basis for a residence right suffices to exclude Art. 83 let. c ch. 2 LTF; once the public law appeal is open, the subsidiary constitutional appeal falls away.
