Kernrechtsfrage
Whether the separate evidence order could be challenged before the Federal Supreme Court without jurisdictional obstacle, in particular in view of irreparable harm.
Extrahierter Entscheid
The order was an incidentally notified decision subject to review only if it could cause irreparable legal harm; the court found it unnecessary to decide the point because the appeal failed on the merits in any event.
Extrahierte Begründung
Procedural evidence orders are generally incidental decisions under Art. 93 LTF and are reviewable only under the strict conditions for irreparable prejudice.
