Questione giuridica chiave
Whether the appeal was admissible despite the missing attachment of the challenged cantonal decision.
Decisione estratta
No. The appellants did not remedy the missing attachment within the set deadline, so the appeal had to be dismissed without entry.
Motivazione estratta
Art. 42(3) and (5) BGG require the challenged decision to be attached; after the court granted a cure period with warning, the uncured defect justified non-entry under Art. 108(1)(a) BGG.
