Kernrechtsfrage
Whether the appellant could be forced to proceed in absentia despite planned travel
Extrahierter Entscheid
The hearing in the appellant's absence was lawful because the inability to attend was self-caused and no sufficient reason justified postponement.
Extrahierte Begründung
A defendant has a right to attend, but may be judged in absentia if he could have participated and failed to do so through his own fault. A planned vacation booked after the summons did not make postponement necessary.
