Questione giuridica chiave
Whether the subsidiary constitutional complaint was admissible against the refusal to renew the residence permit.
Decisione estratta
No admissible constitutional complaint existed because the appellant had no legally protected interest in renewal and could not rely on arbitrariness or proportionality to create standing.
Motivazione estratta
The ordinary public law appeal was excluded under Art. 83 lit. c no. 2 LTF. Under Art. 115 lit. b LTF, mere complaints about incorrect application of law, arbitrariness, or proportionality do not by themselves confer standing when no enforceable right to the permit exists.
