Kernrechtsfrage
Whether the defendant had to expressly and reasoned challenge the first-instance cost allocation in his cross-appeal.
Extrahierter Entscheid
Yes. Because the appeal must be reasoned, appellate review of cost allocation is limited to expressly and substantiated grievances, or to cases where the appeal outcome itself requires review. Since the defendant made no such request, the ordinary allocation of costs according to outcome remained unobjectionable.
Extrahierte Begründung
The court distinguished the current appeal regime from the former code: appellate review is not automatic, but depends on a specific complaint. Although tariff-based cost assessments may be reviewed ex officio, that did not help the defendant here because he did not attack the allocation itself in his cross-appeal.
