Question juridique clé
Whether the constitutional complaint is admissible despite no federal entitlement to the residence permit.
Solution extraite
The applicant lacked a legally protected interest to contest the permit refusal on the merits; only procedural rights could be raised by constitutional complaint.
Motifs extraits
Because no federal right to the permit existed, ordinary review was excluded and a merits attack, including arbitrariness in the substance, was not open; only formal denial of justice claims remained admissible.
