Key legal question
Whether the federal criminal appeal against the cantonal remand ruling was immediately admissible.
Extracted holding
No immediate appeal lay because the ruling was an incidental decision and the statutory exceptions were not met.
Extracted reasoning
The remand did not end the criminal proceedings; the cost ruling attached to the remand was also incidental and caused no irreparable legal prejudice. Nor was it shown that an immediate decision would avoid lengthy and costly evidence proceedings.
