Kernrechtsfrage
Whether the complaint against the order on expert supplementation was admissible due to risk of irremediable prejudice.
Extrahierter Entscheid
Yes; the refusal of certain expert questions could prevent timely clarification of evidence and process prospects and might irreversibly affect later evidence preservation.
Extrahierte Begründung
The court held that the purpose of provisional evidence is to clarify evidentiary and litigation prospects before a main action. If omitted now, later clarification may be pointless. It also accepted a possible risk of evidence loss through planned repair work.
