Kernrechtsfrage
Whether allowing a criminal complaint under § 207(2) StPO necessarily requires annulment of the challenged decision.
Extrahierter Entscheid
No. The appellate complaint court may, where necessary, decide the matter itself or remit it, but it need not intervene if the error does not require correction.
Extrahierte Begründung
Unlike cassation, § 207(2) StPO does not prescribe automatic annulment upon success of the complaint. Because the complaint is a subsidiary remedy against a broad range of judicial acts, the appellate court is given discretion. If the error has no visible impact on the substantive decision, process economy supports leaving the decision in place.
