Question juridique clé
Whether the applicants had standing to bring a constitutional complaint against the residence-permit decision
Solution extraite
Because they had no legal entitlement to the requested residence permits, they could not challenge the merits by constitutional complaint; only procedural-rights claims would be admissible, and none were properly raised.
Motifs extraits
The complaint attacked the substance of the permit refusal under the guise of arbitrariness, disproportionality, and incomplete fact-finding. Such arguments are inadmissible without standing on the merits.
