Key legal question
Whether the federal criminal appeal against the cantonal non-entry decision was admissible despite being directed against an interlocutory decision.
Extracted holding
The challenged decision was interlocutory and produced no irreparable legal disadvantage; the appeal was therefore inadmissible.
Extracted reasoning
The refusal of evidence generally does not cause irreparable harm. The witness was not readily available, but links to persons in Switzerland could secure contact, and an indictment was imminent, so examination before the trial court did not appear harder than before the prosecutor.
