Questione giuridica chiave
Whether the deadline for filing the appeal declaration could be restored under Art. 94 StPO
Decisione estratta
Restoration was denied because the late filing was attributable to the prosecution's own error in using the internal courier and no excusable fault was shown.
Motivazione estratta
The 20-day period under Art. 399(3) StPO is a non-extendable statutory deadline. Deadline restoration is only possible under Art. 94 StPO, requiring credible absence of fault. Fault of helpers such as messengers is imputed to the party, and the prosecution did not show that the courier missed the deadline without fault.
