Questione giuridica chiave
Whether the constitutional complaint was admissible despite no legal entitlement to the residence permit.
Decisione estratta
The appellant had no enforceable right to the permit and therefore lacked standing to challenge the merits by constitutional complaint.
Motivazione estratta
Without a legal entitlement, he could not invoke protected interests on the substance; only procedural guarantees amounting to a formal denial of justice could be raised.
