Whether the appeal against the cantonal decision on security in lieu of detention was admissible
Solution extraite
The appeal was admissible as an incidental criminal decision capable of causing irreparable harm if the applicant could not post the security.
Motifs extraits
Pre-trial detention decisions fall under criminal matters; an incidental decision is reviewable when it may prolong deprivation of liberty because the required security cannot be raised.
