Kernrechtsfrage
Whether the cantonal court could treat the 10 July 2013 filing as an appeal announcement and refuse entry on the appeal.
Extrahierter Entscheid
The filing was an early appeal declaration, not an appeal announcement; the cantonal court had to clarify the mistake and allow correction.
Extrahierte Begründung
Under Art. 399 StPO, appeal announcement and appeal declaration are separate steps. The appellant addressed the competent appeal court and expressly said he wanted to 'declare' the appeal. Because he was unrepresented and the error was timely correctable, the court had a duty under Art. 3 StPO to point it out instead of forwarding the filing as an announcement.
