Question juridique clé
Whether the cantonal ruling refusing file access was immediately appealable despite being incidental
Solution extraite
The ruling was an incidental decision, but the appellant did not show irreparable legal harm.
Motifs extraits
A mere delay in proceedings or higher costs is insufficient. Before a valid first interrogation, Article 101(1) CPP does not give a general right to inspect the file, and the suspect can still remain silent without prejudice to later access.
