Kernrechtsfrage
Whether the complaint against the investigation order was admissible despite being directed against an interim decision.
Extrahierter Entscheid
The challenged decision was an interim decision and the appellant did not show any irreparable harm or immediate final decision effect.
Extrahierte Begründung
Under Art. 93 BGG, an interim decision is only appealable under narrow conditions; the appellant must specifically demonstrate them. He failed to do so, so the complaint lacked sufficient reasoning.
