Whether preventive detention was justified by a serious risk of flight and proportionality.
Yes. The appellant faced serious robbery charges, had no ties to Switzerland, held only asylum-seeker status, and had said he would leave if he did not find work; detention was proportionate for the ordered three-month period.
The court considered the concrete personal circumstances more important than the offence gravity alone, and found a sufficiently probable risk that he would evade prosecution or punishment. The detention period was not close to the foreseeable sentence.
