Kernrechtsfrage
Whether a non-appealable trial-court evidence order can be separately challenged by complaint.
Extrahierter Entscheid
As a rule, such an evidence order must be challenged only together with the appeal against the final judgment. A separate complaint is admissible only if it causes a legal disadvantage that cannot later be remedied, or can only be remedied with difficulty, by the remedies against the judgment.
Extrahierte Begründung
Evidence orders may be reconsidered by the court itself, and the court finally rules on the evidence only in the final decision. Separate interlocutory review is therefore exceptional and depends on irreparable or difficult-to-cure prejudice.
