Kernrechtsfrage
Whether the appeal should be deemed withdrawn because the appellant did not appear at the appeal hearing without valid excuse and without representation.
Extrahierter Entscheid
Yes. The appellant was duly summoned, did not collect the notice, failed to appear, and was unrepresented; the appeal was therefore deemed withdrawn.
Extrahierte Begründung
Under Art. 407 para. 1 let. a CPP, an appeal is deemed withdrawn if the appellant defaults at the appeal hearing without valid excuse and without representation. Service was made to the correct address, the appellant did not collect the mail, and no one appeared on his behalf.
