Key legal question
Whether the cantonal detention order was sufficiently reasoned and justified the continuation risk
Extracted holding
The detention order did not satisfy the constitutional duty to state reasons and did not sufficiently establish repetition risk; the order had to be annulled and the matter remitted for a new decision.
Extracted reasoning
The cantonal decision was too summary, gave no concrete account of the proceedings, the alleged offenses, the prior convictions or the factual basis for a very unfavorable recidivism prognosis, and did not examine substitute measures. The defect could not be cured in the federal appeal proceedings.
