Question juridique clé
Whether the appellant's right to be heard was violated by the immediate arrest order and refusal of provisional release.
Solution extraite
No. In detention matters, the person may be heard only after execution of the measure; the appellant was able to raise his objections promptly in the release proceedings.
Motifs extraits
The purpose of preventive detention would be undermined if prior hearing were required. The decisive point is that the detainee can challenge the detention without delay after arrest.
