Questione giuridica chiave
Whether the subsidiary constitutional complaint was admissible despite the absence of any entitlement to permit renewal.
Decisione estratta
No; without a legally protected interest, X. lacked standing to challenge the permit refusal on the merits.
Motivazione estratta
The case fell outside Art. 83 lit. c no. 2 BGG for an appeal in public law matters. Under Art. 115 lit. b BGG, a foreign national without a right to renewal may only raise procedural grievances amounting to formal denial of justice, not arguments that in substance seek review of the balancing of interests in the permit decision.
