Question juridique clé
Whether the federal appeal against the expert mandate in the seal-lifting procedure was admissible despite its interlocutory nature.
Solution extraite
The decision was interlocutory and did not establish irreparable legal harm; the appeal was therefore inadmissible.
Motifs extraits
The expert acts under judicial supervision for the sorting of electronic data, and any objection to the triage method can be raised later against the final seal-lifting decision. No concrete risk to the investigation was shown at this stage.
