Questione giuridica chiave
Whether the complaint against the investigation order was admissible despite being directed against an interim decision.
Decisione estratta
The challenged decision was an interim decision and the appellant did not show any irreparable harm or immediate final decision effect.
Motivazione estratta
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.
