Question juridique clé
Whether the wiretap records breached the right to be heard because they were undated and unsigned.
Solution extraite
The complaint was unfounded because the cantonal court could treat the objection as procedurally barred under Vaud procedure; the Federal Court would not review cantonal procedural law absent a specific arbitrariness challenge.
Motifs extraits
The accused had not raised the irregularity in time before the first-instance court, as required by cantonal rules, so he could no longer invoke it on appeal. Since no arbitrariness in applying cantonal procedure was pleaded, the Federal Court did not examine the point further.
