Question juridique clé
Whether the cantonal preventive measures were justified by flight risk and proportionate under Swiss constitutional law.
Solution extraite
Yes. In view of the serious narcotics allegations, the likely substantial prison sentence, the appellant's ties to Thailand, and possible financial means, the finding of flight risk was not unconstitutional; the measures were permissible substitutes for detention.
Motifs extraits
The Court recalled that flight risk cannot be based on sentence severity alone, but here additional concrete factors supported it. Mild measures may replace detention only if they can sufficiently neutralize the risk; with pronounced flight risk, passport seizure, exit ban, and reporting duty are admissible.
