Kernrechtsfrage
Whether the appeal was deemed withdrawn under Art. 407(1)(a) StPO because the appellant did not appear at the appeal hearing
Extrahierter Entscheid
The appeal could not be treated as withdrawn because necessary defense was in force, counsel appeared, and the appellant was not validly summoned.
Extrahierte Begründung
Art. 407(1)(a) StPO does not apply where mandatory defense must be guaranteed until the end of the appeal proceedings; the appellant was also not unexcused absent because personal service was required and the court failed to use the prescribed methods of service.
