Question juridique clé
Whether the prolongation of pretrial detention was lawful despite the appellant's challenge to the existence of collusion and recidivism risks.
Solution extraite
The detention could be maintained because a concrete risk of collusion remained, while the court did not need to examine recidivism separately.
Motifs extraits
The court held that a mere abstract risk of collusion is insufficient, but here ongoing investigations, undisclosed documents, and pending analysis of seized material meant the appellant could still destroy or alter evidence. The risk of collusion could not be excluded until those investigations were completed.
