Questione giuridica chiave
Whether the filing was directed against an admissible object of appeal and timely under the BGG.
Decisione estratta
The complaint was not admissible because it did not challenge the cantonal judgment and was in any event late.
Motivazione estratta
Only the cantonal insurance court judgment could be challenged; the filing targeted the IV office and RAV instead. The 30-day appeal period had expired.
