Questione giuridica chiave
Whether the federal appeal could challenge the cantonal decision declaring the cantonal appeal inadmissible as time-barred.
Decisione estratta
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.
Motivazione estratta
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.
