Questione giuridica chiave
Whether the appeal had to be declared inadmissible for failure to submit a copy of the challenged decision after warning and deadline.
Decisione estratta
Yes. The appellant did not comply with the instruction to file the challenged decision, so the appeal was inadmissible under Art. 108(1)(a) LTF.
Motivazione estratta
Art. 42(3) and (5) LTF require attachment of the challenged decision and allow a cure period with warning of inadmissibility. Non-compliance justified non-entry.
