Whether the unmotivated appeal was admissible under Art. 399 para. 3 CPP.
The appeal was inadmissible because no motivated appeal declaration was filed within the statutory time limit and the appellant did not respond to the court's invitation to comment.
Under Art. 399 para. 3 CPP, the appellant must submit a written appeal declaration to the appellate court within 20 days after notification of the reasoned judgment. Since B.________ did not file such a declaration and did not react to the five-day invitation, the appeal could not proceed.
