Question juridique clé
Whether the absence of an oral hearing before the detention court violated the right to be heard
Solution extraite
No. Prolongation detention proceedings are generally written; the defendant had only mentioned a hearing hypothetically and did not justify it.
Motifs extraits
Art. 227(6) CPP provides for written procedure as the rule. The defendant had no absolute right to an oral hearing, and the cantonal court's factual finding was not arbitrary.
