Questione giuridica chiave
Whether the federal complaint met the substantiation requirement under Art. 42 BGG despite the cantonal decision resting on multiple independent grounds.
Decisione estratta
The complaint did not address a self-standing ground sufficient to uphold the non-entry decision, so the substantiation requirement was not met.
Motivazione estratta
If a decision is based on several independent grounds, each decisive ground must be challenged. The appellant failed to discuss the cantonal finding that the restoration request lacked an excusable impediment, which alone justified non-entry.
