Questione giuridica chiave
Whether the subsidiary constitutional complaint is admissible despite no legal entitlement to renewal of the residence permit.
Decisione estratta
The complaint was not admissible on the merits because the applicant had no enforceable right to the permit and therefore no standing to challenge the refusal substantively.
Motivazione estratta
His spouse only held a residence permit, which did not create a derivative entitlement; he also did not show that the child had an independent protected residence status. Ordinary public-law appeal was therefore unavailable, and only a constitutional complaint remained.
