Key legal question
Whether the renewed detention prolongation order was invalid because the previous prolongation had been annulled and the original warrant had expired.
Extracted holding
The annulled order continued to serve as a detention basis until the Chamber of Accusation issued a new decision promptly; the renewed order validly replaced it.
Extracted reasoning
The court held that the effect of annulment does not necessarily occur immediately at the time of the Federal Supreme Court judgment. Where the reasons of the judgment specify that the cantonal authority may cure the defect by deciding again within a short time, the prior order remains a valid detention title until the new ruling. Here the new order followed within days and therefore satisfied the requirement of a prompt decision.
