Kernrechtsfrage
Whether the appeal had to be declared inadmissible for failure to submit a copy of the challenged decision after warning and deadline.
Extrahierter Entscheid
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.
Extrahierte Begründung
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.
