Kernrechtsfrage
Whether the criminal appeal was admissible after the appellant failed to cure the formal defect within the time limit.
Extrahierter Entscheid
The appeal could not be examined because the defect notice was deemed served and no timely correction followed.
Extrahierte Begründung
Under Art. 42(5) BGG, the missing annex had to be filed by the set deadline. The undelivered postal item was deemed served because the appellant had to ensure receipt of court mail. Non-compliance led to non-entry under Art. 108 BGG.
