Whether the appeal against refusal of a second psychiatric expertise was admissible under arts. 393 and 394 CPP
The appeal was inadmissible because the refusal of evidence could be renewed before the first-instance court without irreversible legal prejudice.
Orders refusing evidence are generally not immediately appealable unless the evidence risks disappearing or concerns decisive unresolved facts. A psychiatric expertise can be requested again at trial and is not a transient means of proof.
