Question juridique clé
Whether preventive detention remained lawful after the investigation had been closed and the file sent to the prosecutor.
Solution extraite
Yes. Under Neuchâtel procedure, the detention title continued ex lege after closure of the investigation; no automatic fresh authorization by the chamber of accusation was required.
Motifs extraits
Article 120 CPP/NE applies while the investigating judge is seized. Once the investigation is closed, detention continues and the detainee may still seek release before the investigating judge and then by appeal, so judicial control remains available.
