Kernrechtsfrage
Is the administrative appeal admissible against the interlocutory order on evidence/protocoling?
Extrahierter Entscheid
Yes. The order was independently challengeable because it could cause an irreparable procedural disadvantage to the department.
Extrahierte Begründung
The order concerned both refusal of a means of proof and supplementation of the file; under the applicable procedural rules such interlocutory measures are appealable when irreparable harm is possible.
