Kernrechtsfrage
Whether the appeal was admissible despite the appellant's failure to file the challenged decision and envelope.
Extrahierter Entscheid
No; because the defect was not cured within the deadline, the appeal was deemed withdrawn and therefore inadmissible.
Extrahierte Begründung
Under the cantonal procedural rules, the challenged decision must be attached to the appeal. If the defect is not remedied within the set time limit, the filing is deemed withdrawn.
