Question juridique clé
Whether the federal appeal could challenge the cantonal decision declaring the cantonal appeal inadmissible as time-barred.
Solution extraite
The appeal could concern only the issue of inadmissibility decided by the cantonal court; broader requests on the residence permit were outside the scope of review.
Motifs extraits
The appellant did not specifically and adequately argue arbitrariness in the application of cantonal procedural rules on appeal deadlines and restitution of time limits, as required for a constitutional complaint against cantonal law application.
