Question juridique clé
Whether the constitutional complaint was admissible against the refusal to renew residence permits with no federal-law entitlement
Solution extraite
The applicants had no legal entitlement to renewal of the residence permits and therefore lacked standing to challenge the substantive permit refusal by constitutional complaint.
Motifs extraits
A residence permit subject to discretionary renewal does not confer a right under federal law or a treaty; without a protected legal position, no rights are infringed by refusal. Only procedural complaints amounting to formal denial of justice could be heard, but the applicants attacked the substantive assessment and balancing of interests.
