Questione giuridica chiave
Whether the appeal was inadmissible because the challenged decision was not submitted despite a deadline with threat of non-entry.
Decisione estratta
The appeal could not be examined because the appellant failed to cure the missing attachment within the time limit.
Motivazione estratta
Under Art. 42(3) and (5) BGG, an appeal must include the challenged decision; if missing, a remedy period is set with warning of non-entry. The reminder was sent by registered mail to the address stated by the appellant and, as uncollected, was deemed served under Art. 44(2) BGG. The statutory consequence therefore applied.
