Kernrechtsfrage
Whether the district court's order was an appealable interim decision causing irreparable legal harm or saving extensive evidence-taking under Art. 93 BGG.
Extrahierter Entscheid
The order was an interim decision, but neither irreparable legal harm nor a case of avoiding extensive evidence-taking was shown.
Extrahierte Begründung
Continuing the criminal proceedings did not create a legal disadvantage for the defendant; the alleged harm concerned SBB, not the defendant. The evidentiary record was largely complete and the remaining questions were mainly legal.
